Supply, Delivery, Installation, and Commissioning of Mobile Laboratory Equipment for the Departments of Biology, Chemistry, and Physics at the Faculty of Mathematics and Natural Sciences, University of Pristina, Kosovo

New clarification added: Clarification request no. 36With reference to LOT2 Item 2.16 / 2.21 – Contamination Monitor, the technical specification currently states:“Energy Range: Down to ~30 keV (beta); up to 1 MeV (gamma).”We would like to kindly request a clarification regarding the lower limit of the beta energy range.In practice, for portable contamination monitors using large-area scintillation detectors, detection of beta particles below approximately 50 keV is not technically feasible nor necessary. In this low-energy range, beta particles have very limited penetration in air and are effectively absorbed by the entrance window and protective layer of the detector. As a result, even instruments specified “down to 30 keV” do not achieve reliable or meaningful detection at that level.For this reason, most reference-class contamination monitors in laboratory and nuclear-medicine applications are designed and calibrated for beta energies starting from about 50 keV and higher, which fully meet all practical requirements for contamination monitoring on surfaces, clothing, and skin.We therefore kindly ask the Evaluation Committee to allow a minimum beta energy detection threshold of approximately 50 keV instead of 30 keV, as this represents the realistic and technically justified operating range for the intended use.Clarification response no. 36Thank you for your technical clarification. Accordingly, the specification will be ammended as follows: Item 2.21: Line 4: Energy Range: Down to ~50 keV (beta); up to 1 MeV gamma

New clarification added: Clarification request no. 35Kindly confirm that for LOT2 item 2.12  Vacuum packing machine whether the indicated weight of approx. 44 kg for the Vacuum Packaging Machine is only indicative, since models with the same or higher performance may have a higher weight (up to around 100 kg).We would like to clarify if such variation can be accepted, as weight does not affect the equipment’s performance provided that all primary technical specifications (vacuum capacity, sealing bar length, cycle time, and material) are fully met or exceeded. Clarification response no. 35For LOT 2 – Item 2.17: Vacuum Packing Machine, we confirm that the previously indicated weight (approx. 44 kg) is indicative only and not a performance-related specification. Hence  Item 2.17  specification line 4 Weight : Approx. 44 kg will be removed 

New clarification added: Clarification request no. 34We kindly request clarification regarding LOT2 Item  2.10  Analytical Balances as the provided specifications appear to contain elements that may correspond to different balance categories.Specifically, the weighing range (minimum 0.2 g to 5 kg) and the readability (0.1 mg) are not proportionate to each other, since analytical balances typically feature readability in the microgram range with much lower weighing capacities (generally up to 200–300 g). A readability of 0.1 mg for a 5 kg weighing capacity would exceed the technical limits of analytical balances.Could you please confirm whether the intended item should be:An analytical balance (e.g., readability 0.1 mg, capacity up to ~200–300 g), orA precision / top-loading balance (e.g., capacity up to 5 kg, readability 1 mg or higher)?Clarification response no. 34We confirm that the requirement is intended for an analytical balance, and therefore the previously stated weighing range was not technically aliged and accordingly, the specification is hereby amended as follows: Item 2.15: Line 7: Weighing range : 220g- 320g . Please note that the readability requirement remains unchanged as specified in the tender document. 

New clarification added: Clarification request no. 33For LOT 2 V1 Item 2.9  Lead shield with supporting table(with LN2 sensor and monitor) it is specified:Lined with 9.0 mm copper covered with tinWe kindly request your approval to offer an equivalent Lead Shield with Supporting Table (with LN₂ sensor and monitor) that uses a graded liner composed of 1.0 mm tin and 1.6 mm copper, instead of the originally specified “9.0 mm copper covered with tin.”The proposed design provides the same protective performance and function because:The 100 mm lead wall is the main radiation barrier.The 1 mm tin + 1.6 mm copper liner effectively prevents interference from lead X-rays, following the standard graded-Z shielding principle used in gamma-spectroscopy shields.This combination ensures easy cleaning, corrosion protection, and mechanical stability, exactly as in the thicker liner design.We will provide all technical documents, certificates, and—if requested—attenuation test results proving the same radiation protection level as the original specification.We kindly ask the authority to accept this equivalent configuration for the project.Thank you for your understanding and consideration. ​Additionally, we kindly request that the CE-marking requirement be waived for this item.Lead-shielding assemblies are passive radiation-protection products, not electrical, medical, or measuring devices subject to CE directives (such as LVD, EMC, or MDR). These shields are typically governed by material-safety and fabrication standards (e.g., ISO 9001, ISO 14001, radiation-shielding safety standards) rather than CE conformity, which is therefore not applicable or necessary for this type of product.We remain at your disposal to provide any supporting documents or test data the Authority may require to confirm compliance and functional equivalence.Clarification response no. 33We acknowledge that the graded-Z shielding designs using combinations such as tin and copper can provide equivalent attenuation performance to thicker copper-based liners. As part of the clarification, the specification has been broadened to allow equivalent graded liner configurations while ensuring that the required shielding performance is maintained. Ammended specification for LOT 2- item 2.9 Lead shield with supporting table (with LN2 sensor and monitor). Line 3:The inner graded liner shall be composed of corrosion-resistant materials such as copper and tin, with a total effective shielding thickness equivalent to the originally specified 9 mm copper-based design. Alternative graded-Z configurations (e.g., tin + copper combinations) may be accepted, provided they demonstrate equal or superior attenuation performance and are supported by relevant technical documents and test reports.Please proceed to submit all certifications and supporting documents available for the offered lead-shielding assemblies. Any equivalent certifications, such as radiation-shielding safety standards, material-safety documentation, quality management certifications (e.g., ISO 9001, ISO 14001), or other relevant conformity evidence, may be considered during the technical evaluation.

New clarification added: Clarification request no. 30Item 1.9 - Peristaltic pump,A) Can we offer TPE tubing: Pure Weld ? In addition, there is nothing about tubing diameter in the tender.B) Therefore, RPM data shows that tender issuer have certain pump on his mind (this rpm data is not relevant for pump performance), and, In which environment pump will work (food, biopharma,)?C) Is the manual control enough or customer need analog (4-20mA) or digital?Clarification response no. 30Please note that Manual control is the minimum requirement; any equivalent or superior tubing material mau be offered provided manufacturer data confirms chemical compatibility and performance; bidders must supply pump-head details and flow-vs-RPM data to demonstrate the required 30–3000 mL/min range is met.

New clarification added: Clarification request no. 26Item 1.8 Freezer -861) In almost, all cases -86°C internal chambers are completely dark. Installing lights inside would cause refrigeration inconsistencies and even affect sample preservation?Can you please review this specification?Clarification response no. 26Please note the internal light is to remain as per the specification for operational convenience; however, absence of the internal light will be considered minor deviations  if overall performance and safety remain unaffected.

New clarification added: Clarification response no. 24Answer to Question 1: The intent of the specification is to ensure the system includes four spatially separated lasers that cover the violet(~405 nm), blue (~488 nm), yellow (~561 nm), and red (~637 nm) spectral regions to enable multicolor flow cytometry applications. Minor wavelength deviations (± 5 nm) within the same spectral bands are technically acceptable and will not impact compliance. Therefore, no ammendment to the specification is required, as the current requirement already accomodates typical manufacturer variations within (± 5 nm) tolerance. Answer to Question 3: Item 1.1 Flow cytometer , line 2 of specification:  The beam dimension will be removed from the specification and line 2 will be ammended as follows: Laser profile :flat-top laser beam profile optimized for uniform illumination across the flow cell, ensuring high sensitivity for small particles (≥70 nm) and compatibility with multiple detection channels. Each laser shall be solid-state with a minimum output power of 40 mW or more at the flow cell.Answer to Question 4: Item 1.1 Flow cytometer, Line 4 will be ammended as : Flat-top laser specified at the flow cell: Either Coefficient of variation (CV) <3% over the width of the flat-top laser or Robust coefficient of variation (rCV) ≤ 6% is acceptable, whichever demonstrates lower variation, to ensure equivalent or superior instrument performance while maintaining fairness for all technologies. Answer to Question 5:Bidders may offer instruments with equivalent or superior flow cell design and optical performance, including silica cuvettes and detection of particles from 70 nm; such offers will be considered substantially compliant with the specifications.Kindly note that it is mandatory to provide local agent/service center in Kosovo.We thank you for your requests and have incorporated certain amendments that are appropriate to encourage broader participation; please note that offers meeting or exceeding the stated specifications are equally considered substantially compliant. We encourage submission of such offers, supported by datasheets, scientific publications, or other evidence demonstrating superior performance, as the specifications represent the minimum required for intended functionality.

New clarification added: Clarification request no. 24We would like to strongly emphasize that, based on the established decision-making practice for Public Procurement procedures, it is clear that eliminating competition by establishing precise technical specifications that correspond to a specific product is inadmissible under the law. The reason is that such a procedure unreasonably restricts competition and constitutes a prohibited form of indirect reference to a specific product. Our goal is to allow fair competition and to submit a bid for a more technologically advanced and economically advantageous solution. We want to provide you with equivalent equipment with superior technical characteristics, respecting using purpose and having a large number of installations and publications that certify the quality of the product. A strong support for technical service and applications in the region, are facts to be considered for high values acquisitions. Our flowcytometer is coming with for optimal operation parameters corresponding to technology, a detection system capable of recording signals across the entire spectral range 365-829nm with a detection sensitivity far superior to the minimum requirements (FITC <= 5 MESF, PE <= 4 MESF, APC <= 3 MESF), can be equipped with a module for detecting particles from 70nm, which will allow the extension of applications for extracellular vesicles and exosomes, a flow rate of up to 200uL/min for applications involving the detection of rare particles, To this end, please accept the following changes to the minimum technical specifications:- four spatially separated lasers including: 405 +/- 5 nm violet, 488 +/- 5nm blue, 561 +/- 5nm yellow, 637 +/-5nm red. Producers are using lasers with slightly different wavelengths in order to excite fluorochromes, keeping the range of wavelegth intervals with high coverage for blue, violet, red, yellow. Same important as excitation wavelenghths is the lasers power, and our instrument is coming with solid state lasers, with minimum 50mW power.- possibility to upgrade to more lasers in the future in the location where instrument is installed. - our lasers have flat-top laser beam profile, optimize for detection of small particles, from 70nm and for higher number of channels. We ask you to remove dimensions 10 x 50 μm(+/- 10%) which indicates specific instrument of one producer and restricts access to procedure for other producers, without bringing benefits for users. - our instrument comes with superior number of channels for every laser, offering 48 fluorescence detection channels for required configuration. For this reason, we ask you to consider the number of detection channels as superior qualitative criteria.- request for coefficient of variation (CV) <3% over the width of the flat-top laser is a parameter composed by different coefficient variations on each channels, but not showing variability of each channel. CV% = standard deviation/mean × 100%, is a measure of variation in signal intensity generated as particles pass repeatedly through the laser beam, and is expressed as a percentage of average signal intensity. The coefficient of variation is a parameter that correlates with the linearity of the signal and is wavelength specific. Our technology uses non-exclusively compared to other technologies rCV% (robust coefficient of variation) as being more relevant than CV% for populations that do not follow a normal Gaussian distribution and is accepted as a reference in flow cytometry where gain (signal amplification) is used. Depending on the wavelength, the rCV% for the offered instrument varies. Daily QC assesses the instrument’s optical alignment and the system performance drift by measuring rCVs and gains needed to place the beads at the target locations for each detector. In conclusion, our instrument is able to resolve calibration particles starting with a fluorescence resolution of 1.63% CV and with a signal linearity of FITC R2 >=0.995 / PE R2 >=0.995. As non-discriminatory reference, we propose use of Euroflow criteria applied for flowcytometers used for identifying different major and minor lymphoid subsets. Please accept rCV% as equivalent parameter and instrument with next values: <6% for FSC channel, <8% for SSC and <6% for third channel of each laser (blue, red, violet).- for specification: Flow cell: High quality flow cell (Stainless steel/Quartz) cuvette gel coupled to 1.2 or higher numerical aperture (NA) collection lens, 200 x 200 μm (+/-10%) - we'd like to propose instrument with Silica cuvette and high numericar apperture lens, Silica being superior to Quartz when microscopy lens are involved. Every producer puts efforts in capturing singnals, even weak or rare signals and technical dimensions might vary. Please accept our instrument with proven detection sensitivity for small particles starting with 70nm and remove specific values of NA 1.2 and 200 x 200 μm (+/-10%) where specific product and producer are indicated. - please consider as superior qualitative criteria a better sensitivity of detection and accept our instrument with FITC: ≤ 5 MESF PE: ≤ 4 MESF APC: ≤ 3 MESF Pacific Blue: ≤ 4 MESF. Sensitivity of detection is the most important parameter for a flowcytometer, due to the fact rare events and low expression markers are those bringing value to research and orient users to a more specific path. Most of the instruments in the market can analyze conventional populations and we understand your acquisition purpose is to cover developments for now and upcoming years. Our instrument allows you to work with regular cell populations or bacteria, but also with extracellular vesicles, exosomes, oncosomes, nanoparticles, viruses in the range on nanometers. - please accept better carryover of <0.1%.- please remove heat dissipation parameter as being something specific to different technologies and restrictive in terms of value <150W. Considering environmental protection measures and rules, we suggest to replace this criteria with instruments complying with low energy consumption, according European Union Energy Efficiency Directive.Due to the fact every producer is optimizing the workstation for optimal workflow with the main instrument, please find below our requests for adjusting and considering our solution as equivalent solution:- our instrument comes with workstation where Windows 11 is installed, this being last version. Please accept superior version of Windows and change restrictive parameter Windows 10.- our instrument comes with better workstation with 64 GB RAM. Please change restrictive parameter of 32 GB RAM. - our instrument comes with 1 larger monitor of 32 inch, 4k resolution. Please accept 1 larger monitor of 32 inch and 4k resolution as equivalent. - our instrument comes with desktop computer, with reduced dimensions, but not named minitower. Please remove "minitower" from specifications, being restrictive not only for our technologies, but for other also.- please accept as hard drives 1 TB SSD and 2 TB SSD (secondary), type NVME SSD, together with external 2 TB for storage. Our computer is coming with hard drives with superior technology than SATA, named NVME, ensuring higher speed. Regarding request: Bidders should provide the contact details of the Local Agent/Service Center assigned in Kosovo for post delivery services, including the name of the service center, contact details, name, phone number, email - please accept Local Agent/Service Center in the region with maximum 24-48 hours time for intervention with communication in native language. 

New amendment added #3: Deadline for clarifications has been extended until 21 November 2025.Deadline for submission of bids has been extended until 27 November 2025.

New amendment added #2: UNOPS advises on the following points as below that HAVE BEEN AMENDED:Please be informed that the deadline for clarifications and submission will be extended as follows:Deadline for clarifications has been extended until 21 November 2025.Deadline for submission of bids has been extended until 27 November 2025.In addition to this extension, an amendment to the solicitation documents will also be shortly issued.UNOPS advises to remain up to date with the published amendments.

New clarification added: Clarification request no. 32 Regarding the deadline for the tender submission, please be informed that we are currently in contact with multiple manufacturers. As the tender includes a large number of items with diverse and complex technical requirements, we have found that the current submission deadline does not allow sufficient time for proper assessment and preparation.In particular, the tender involves at least 20 different manufacturers, and each item requires detailed evaluation and analysis in accordance with the tender specifications. Therefore, after careful consideration, we believe that the current deadline of 20 November 2025 is too early.We kindly request that the deadline be extended by at least 30 days to allow vendors adequate time to prepare and submit a comprehensive and compliant proposal.Clarification response no. 32We are considering the request to extend the deadline for bid submission and are currently reviewing the appropriate number of additional days. You will be notified shortly.

New clarification added: Clarification request no. 31Regarding Item 1.1 – Flow Cytometer, after reviewing the technical specifications provided, we would like to respectfully raise a few points for clarification and possible revision.It appears that several specifications are uniquely aligned with the features of a specific manufacturer, which may unintentionally limit fair competition. Therefore, we kindly request the opportunity to propose an instrument with equivalent or superior performance characteristics. All technical equivalencies and performance data will be fully documented in our submission.Please find our detailed comments below:        ​1. Laser Type:           Most flow cytometers available on the market use Gaussian lasers, whereas the specification refers to flat-top lasers, which are available in very limited models. Our proposed system uses high-stability Gaussian lasers, covering the full wavelength range required by UNOPS.Performance (CV/rCV):Our system provides Gaussian lasers with a robust coefficient of variation (CV) below 3%, meeting or exceeding the performance level described in the tender specifications.Fluidics System:Our model uses a periodic-driven fluidics system instead of a vacuum-driven one. We would appreciate clarification on the requirement for vacuum-driven fluidics, as both approaches deliver comparable—if not superior—performance in terms of stability and reproducibility.Sample Volume:Our instrument requires a minimum sample volume of 45 µL. We kindly ask if it would be acceptable to offer an optional configuration achieving the specified 30 µL minimum, or if flexibility can be provided on this point.Event Rate:While our system can technically achieve rates up to 30,000 events/second, such speeds are rarely used in standard laboratory workflows. We therefore request consideration for revising this specification to better reflect typical operational requirements.Specification No. 18:Based on our assessment, this specific requirement appears to align exclusively with Thermo Fisher instrumentation. We respectfully request that this specification be reviewed or generalized to allow for equivalent systems from other manufacturers that can deliver identical analytical performance.Clarification response no. 31The specification for a flat-top laser beam profile is intentionally included to ensure the system's sutability for advanced- reasearch applications rather than routine diagnostic use. The flat-top requirement remains unchanged.Please note that offers meeting or exceeding the stated specifications are equally considered substantially compliant. We encourage submission of such offers, supported by datasheets, scientific publications, or other evidence demonstrating superior performance, as the specifications represent the minimum required for intended functionality.

New clarification added: Clarification request no. 29Regarding lot 3 -  Raman SpectrometryAre you looking for a benchtop Raman system or a handheld device?Clarification response no. 29The specifications clearly describe a Confocal Raman Microscope integrated with a spectrometer and optical microscope, including multiple objectives, motorized XYZ stage, automatic laser switching and calibration, and PC-based control software.Please note these features are characteristic of a benchtop system and not a handheld Raman device.

New clarification added: Clarification request no. 27As the LOT 2 – Supplying with Physics Products has recently been divided into an additional LOT, we kindly request that you further separate products 2.18, 2.19, 2.20, 2.21, and 2.22 into another LOT.This adjustment would help increase the competitiveness of the offers and allow us to submit a proposal for our products accordingly.In this case you will have the offer from the companies working on such products, and will support us to offer our products too.Clarification response no. 27We will take this request into consideration and separate these items into a separate lot.

New clarification added: Clarification request no. 25Item 1.23 Incubator,2) Can we offer 150 Liter?11) Can we offer Venting Valve?Item 1.28 Membrane Vac. Pumps8) Can the handle be installed manudally?Item 1.30 Lab incubator for Micro.1) Can we offer Forced circulation method?5) Can we offer +4 - 60 °C?13) Can we offer SPCC steel with  powder coating?Item 1.34 Pasteur's Oven5) Can we offer 0.5 °C?Clarification response no. 25Answer to question 1 and 2 Item 1.23: Please note that bidder may offer an incubator with capacity of 150 L, which is acceptable. However please note that venting valve cannot be considered an equivalent alternative to the required adjustable air flap, as it does not ensure the necessary air mixing for uniform temperature and gas distribution within the chamber.Answer to question 3:Item 1.28:Line 8.  Please note that while the inclusion of a tensile handle is desirable for ease of handling, it is not critical to the performance or functionality of the membrane vacuum pump. Equivalent designs or alternative handling features that do not compromise performance will also be considered fully compliant.Answer to question 4: Item 1.30: Yes you can offer a Forced circulation method. Any incubator providing uniform conditions through active air movement is considered compliant.The offered range of +4 °C to +60 °C does not meet the minimum requirement (sub-ambient capability) hence will not be acceptable.Please note that while SPCC steel with powder coating provides adequate protection in general laboratory environments, it does not offer the same level of corrosion resistance and durability as stainless steel, especially under humid or chemical exposure. Therefore, SS construction remains the preferred and compliant option.Item 1.34:Answer to Question 1 : he specified accuracy of ±0.1 °C is required to ensure reproducible and validated results for temperature-sensitive processes. An offered accuracy of ±0.5 °C does not meet the minimum requirement and is therefore not acceptablele. 

New clarification added: Clarification request no. 23Item 1.2.Line 3) Can we offer 35 sample positions, and 21 reagent posotion (refrigerated)?Line 5) Can we offer 2 wavelength?Line 7) Can we offer 4 cahnnels fo measuments?Clarification response no. 23After review, we note that the suggested modifications , including reduction in reagent positions, optical wavelengths, and measurement channels, would result in lower analytical and operational performance compared to stated requirements. Therefore, the original requirement shall remain unchanged. We encourage bidders to submit offers that meet or exceeds the current requirements. Any offer that exceeds the current specifications will be considered substantially compliant. 

New clarification added: Clarification request no. 22Can you please review once again the possibility to extend the deadline of the tender for a least 15 days. This request is done also from other operator since most of the manufacotring companies at attending a huge exhibition such as Medica 2025.Clarification response no. 22We are considering the request to extend the deadline for bid submission and are currently reviewing the appropriate number of additional days. You will be notified shortly.

New clarification added: Clarification request no. 21Regaridng item 1.1 Flow Cytometer:1) Can gaussian lasers be acceptable instead of only flat-top.?2) Can you please let us know why heat dissipation would be important for such and instrument?Clarification request no. 21Answer for question 1:The specification for a flat-top laser beam profile is intentionally included to ensure the system's sutability for advanced- reasearch applications rather than routine diagnostic use. Gaussian lasers, with their central intensity peak and weaker edges, do not provide the same level of signal uniformity and reproducibility, and therefore cannot be considered fully equivalent. The flat-top requirement remains unchanged.Answer to question 2:The heat dissipation parameter (<150W) ensures thermal stability of the lasers, detectors, and fluidcs system. Proper heat management is essential to maintain signal stability, detector sensitivity, and reliable fluidics operation, particularly in long-duration environment. This specification is therefore relevant and will be retained.

New clarification added: Clarification request no. 20Question 1: You have requested for - Manufacturer ISO 14001 or similar issued (English version should be provided with offer) Certificate should be issued by Conformity Assessment Bodies (CABs), Notified or Accredited bodies by the International Accreditation Forum (IAF)- Many reputable and compliant manufacturers operate under an environmental management system that fully complies with the principles and requirements of ISO 14001 that includes documented environmental policies, objectives, monitoring processes, and continuous improvement measures equivalent to those required by this standard but are not formally certified from an accredited body.- We kindly request that compliance with ISO 14001 requirements, supported by relevant documentation, be considered acceptable in a written statement form from the manufacturer ensuring that environmental management practices are consistent with the intent and framework of the ISO 14001 standard.- Accepting this request will open the competition and allow participation from capable manufacturers who meet all technical and environmental performance standards.Clarification response no. 20Please note that as per our procurement manual, the implementation of an Environmental Management System (EMS) is a mandatory requirement, however, we acknowlwdge that ISO 14001 certification is not the only means of demonstrating compliance. Therefore, the requirement will be amended as follows:" The manufacturer shall provide a valid ISO14001 Environmental Management System (EMS) certificate or  an organizational environmental sustainability policy, or  an equivalent document demonstrating commitment to environmental sustainability."

New clarification added: Clarification request no. 19Item 1.86) Can we oofer manual defrost system, since this does not change the perfomance of the product?7) Can we offer static refregerator?14) Can we offer mechanicaly key?15) Can you without the internal light, this specification does not effect the perfomarnce of the product at all?Clarification response no. 19The proposed amendments represent reductions in essential performance and safety features. Manual defrost and static refrigeration systems are not acceptable, as they compromise temperature stability and sample integrity. The mechanical key lock may be accepted only if it ensures equivalent security and alarm functionality, while omission of the internal light may be considered acceptable only if it does not affect operational safety or usability. 

New clarification added: Clarification request no. 18 Item1.8 - Equipment provided with not less than four (4) internal compartments with removable storage sliding drawers。Is it acceptable to offer removable shelves without  sliding wheels?Clarification response no. 18Removable shelves without sliding mechanisms do not provide equivalent functionality in terms of accessibility, user convenience, and spill prevention. Therefore, the offered configuration without sliding drawers is not acceptable.

New clarification added: Clarification request no. 17We respectfully request the separation of items 1.1, 1.2, 1.4, and 1.5 into a separate lot.These items are complex laboratory instruments with a distinct operational principle, specialized technology, and maintenance requirements. They differ significantly from the routine daily-use laboratory consumables and basic devices such as items up to 1.37.The sophisticated items require:Specialized technical expertise for installation, calibration, and operation.Dedicated maintenance contracts and technical support.Qualified manufacturers and authorized distributors to ensure proper servicing, warranty compliance, and long-term sustainability.Combining them into a single lot with general laboratory products restricts fair competition, as suppliers of basic consumables typically do not have the technical capacity or authorized certification to supply and service high-complexity instruments. This may lead to:Reduced market competitionHigher procurement riskDifficulty ensuring proper after-sales service and maintenanceTherefore, separating these items ensures fair participation, technical compliance, and sustainable use of the equipment.Clarification response no. 17We will take this request into consideration and separate these items into a separate lot.

New clarification added: Clarification request no. 16 We would like to address the requirement stating that manufacturing companies must hold the ISO 14001 certification. We wish to highlight that ISO 14001 is not a mandatory certification for manufacturers and, as such, many reputable and internationally recognized manufacturing companies may not possess it, given that it is an optional standard.In light of this, we kindly request that you reconsider the requirement and allow for alternative compliance criteria or equivalent environmental management certifications, where applicable.Clarification response no. 16Please note that as per our procurement manual, the implementation of an Environmental Management System (EMS) is a mandatory requirement, however, we acknowlwdge that ISO 14001 certification is not the only means of demonstrating compliance. Therefore, the requirement will be amended as follows:" The manufacturer shall provide a valid ISO14001 Environmental Management System (EMS) certificate or  an organizational environmental sustainability policy, or  an equivalenet document demonstrating commitment to environmental sustainability."

New clarification added: Clarification response no. 15Lot#2 position 2.17 Scanning Electron MicroscopeAfter carefully reviewing the tender documentation and the current lot structure, we have noticed that the electron microscope has been included in the same lot as the physics equipment. This grouping creates significant difficulties and, in practice, prevents participation by companies specialized in laboratory equipment, due to the fundamental difference in the nature of these devices.Firstly, the electron microscope is an advanced analytical laboratory instrument, used for scientific and microscopic analysis at nano-level, while physics equipment generally consists of didactic and experimental tools designed for educational demonstrations in physics. These two categories have completely different purposes, technologies, and operational requirements.Secondly, suppliers of laboratory instruments are companies specialized in providing and servicing analytical equipment and typically do not supply physics teaching tools. Conversely, companies offering physics demonstration equipment are not authorized or certified to import, install, or maintain electron microscopes. Including both types of products in the same lot therefore restricts fair competition and excludes qualified laboratory equipment suppliers.Furthermore, the electron microscope requires specific installation conditions, technical training, and after-sales maintenance, which differ substantially from the requirements of standard physics instruments. These technical obligations cannot be fulfilled by general physics equipment suppliers.Since this grouping is not technically or functionally justified, we respectfully request that the electron microscope be separated into an independent lot, allowing equal competition and fair participation among all qualified and specialized operators.Such a separation would also align with the principles of public procurement, which emphasize equal treatment, broad competition, and logical lot division according to the nature of the equipment.Clarification response no. 15Please be informed that Item 2.17, currently positioned under Lot 2 – Scanning Electron Microscope, will be separated and issued as a standalone lot through an upcoming amendment.

New clarification added: Clarification request no. 10Item 2.22 Scanning Electron MicroscopeLine 1. Please include W as acceptable thermionic source if the bidder includes filaments for equivalent lifetime of 1 LAB6 or CeB6. Advantage being on-site replacement -lower maintenance costs?Line 12. May we offer a bigger active area of 30 mm2 with 133eV resolution?Line 14. Please allow 2000 channels?Line 15.1 Please allow motorized x: 40 mm, y: 40 mm as a more stable and repeatable solution?Line 16.1 Could you accept 36 standard 12.7 mm stub as alternative?Line 16.2 We would like to check if 80 mm diameter and 50 mm height would be acceptable for the end user as it can take the same number of samples required?Clarification response no. 10Answer to Question 1. The requirement for a long-lifetime thermionic source (LaB₆ or CeB₆) is intended to ensure high beam stability, brightness, image quality, and reduced maintenance downtime suitable for university-level research and training. Alternative thermionic sources may be considered ONLY IF the bidder can provide verifiable technical documentation demonstrating equivalent or superior brightness, lifetime, and emission stability, rather than equivalent cumulative lifetime through spare filaments. Hence, the specification remains the same .Answer to Question 2. Bidders are encouraged to propose equivalent or superior configurations. Offers demonstrating improved performance parameters, such as larger detector active area or enhanced sensitivity, will be considered substantially compliant. Minor deviations in parameters that do not materially affect analytical performance or functionality may be deemed technically acceptable during evaluation.Answer to QUESTION 3.Bidders may offer a multi-channel analyzer with 2,000 channels at 10 eV/ch.Answer to Question 4.The 100 × 100 mm sample size requirement was defined to accommodate a wider range of academic and research samples, including larger specimens used in advanced university experiments. Reducing this capacity would limit the scope of experiments and future flexibility; therefore, the specification cannot be modified.Answer to Question 5.Yes, 36 standard 12.7 mm stubs are acceptable as an equivalent alternativeAnswer to Question 6.The 100 × 100 mm sample size requirement was defined to accommodate a wider range of academic and research samples, including larger specimens used in advanced university experiments.

New clarification added: Clarification request no. 4In reference to the items listed under Lot No. 2, we would like to bring to your attention that the specifications for the following items — 2.1, 2.2, 2.3, 2.4, 2.5, 2.24, 2.29, 2.30, 2.31, 2.32, 2.33, 2.34, 2.36, and 2.37 — appear to be written in a way that suggests compatibility with only one manufacturer, PHYWE (Germany).We have confirmed that this manufacturer was informed about the tender several months in advance and has declined to provide offers to other companies. As a result, these items are effectively restricted to a single supplier, making it impossible for other companies to apply for the entire Lot No. 2.In view of the above, we would like to ask that these items be separated into an individual lot. This adjustment would enable other suppliers to submit competitive offers for the remaining items, helping to ensure a fair and transparent procurement process with broader participation.Clarification response no. 4The items listed in Lot 2 are provided by the end users based on their curriculum and laboratory needs. These are specialized physics training instruments and only a few manufacturers including PHYWE ( Germany ) were identified as manufacturers capable of meeting the required experimental setup. However, the amendment will be done and these items will be separated into different lots. Bidders are encouraged to offer equipment from ANY manufacturer, provided that they can demonstrate that the proposed system is equivalent or superior in functionality and performance to the specification indicated.

New clarification added: Clarification request no. 3:For  Lot 2, item 2.22 SEM Microscope, can you please clarify regarding the technical specification position:For specification no. 1. Would you consider an acceptable thermionic source if the bidder includes filaments for an equivalent lifetime of 1 LAB6 or CeB6. Advantage: being on-site replacement -lower maintenance costs.For specification no. 15.1: Please allow motorised x: 40 mm, y: 40 mm as a more stable and repeatable solution.For specification no. 16.2: Would you consider whether 80 mm diameter and 50 mm height would be acceptable for you, as it can take the same number of samples required?Clarification response no. 3:Lot 2, Item 2.22 - please see the response below.For specification no. 1. The requirement for a long-lifetime thermionic source (LaB₆ or CeB₆) is intended to ensure high beam stability, brightness, image quality, and reduced maintenance downtime suitable for university-level research and training. Alternative thermionic sources may be considered ONLY IF the bidder can provide verifiable technical documentation demonstrating equivalent or superior brightness, lifetime, and emission stability, rather than equivalent cumulative lifetime through spare filaments. Hence, the specification remains the same .For specification no. 15.1: Regarding the stage, the specification for a fully motorized 2-axis stage with X–Y travel range of 100 mm is maintained to ensure adequate sample coverage, precision, and operational flexibility.Therefore, a 40 mm × 40 mm travel range would not meet the required specification. Hence the specification remains same.For specification no. 16.2: The 100 × 100 mm sample size requirement was defined to accommodate a wider range of academic and research samples, including larger specimens used in advanced university experiments. Reducing this capacity would limit the scope of experiments and future flexibility; therefore, the specification cannot be modified.
