## Summary

The University of Edinburgh, a central purchasing body located in Edinburgh, UK, has completed a procurement process for a "High Pressure Vitreous Freezer" required by its School of Physics and Astronomy. This device, crucial for experimental sample preparation, allows freezing at exceptionally high rates to preserve sample structures without ice crystal formation. The procurement, carried out through a competitive procedure with negotiation, was awarded to SciQuip Ltd, a small to medium-sized enterprise. The contract, valued at £267,160, was signed on 5th January 2026, and the installation, commissioning, and testing of the equipment are set to be completed by the end of June 2026. The procurement aimed to acquire goods under a selective procurement method, within the education industry category, in the City of Edinburgh (UKM75 region).

This tender presents significant opportunities for businesses, especially those specialising in high-technology scientific equipment. With the procurement method involving negotiation, companies offering comprehensive support, high-quality equipment, and advanced service options can distinguish themselves. Businesses that can provide additional services, such as training and extended warranties, along with robust technical capabilities, are well-suited to compete in tenders like this. Additionally, the University of Edinburgh encourages community benefits from its supply chain, meaning businesses offering sustainability initiatives or local socioeconomic contributions could gain an advantageous position in future procurements.

## Notice

The School of Physics and Astronomy has a requirement for a 'High Pressure Vitreous Freezer' (HPVF); this is a device that freezes samples to extreme low temperature at an exceptionally high rate to essentially 'freeze a sample in time'. If a sample is cooled at a slower rate ice may form within/on fragile samples (for example cells), which would swell/crystalise and destroy the nano/microstructure of the sample. Freezing at an exceptionally high rate freezes the sample faster than ice can form, avoiding this issue. This machine will be used for experimental sample preparation.

### Lot Information

Lot 1

DETAILED SPECIFICATION ESSENTIAL: - The ability to vitreously freeze small volumes (specimen carriers described later) of soft and liquid samples by using a combination of high pressures and liquid nitrogen - Must achieve a minimum cooling rate of 2000K/s - Must be able to exert pressures on the sample in the range of 1900 - 2200 bar during the freezing process to inhibit ice nucleation - Use 3mm and 6mm diameter planchette specimen carriers to hold the sample during freezing - Output freezing parameters after the freezing process - Vitreously freeze non-biological and biological samples up to 200 um thick - Use mains electricity in the lab and conform to UK/CE electrical safety standards. - Installation, commissioning and testing of the equipment. - User Training provided. - Access requirements for the lab: Fire exit width: 139cm. Lab door width: 130cm(W) * 210cm(H); Corridor: 159cm(min width); Weight: Passes through corridors with areas of possible max weight "not exceeding 580kg per square metre". - 1 year manufacturer's parts and labour warranty - Basic level of service contract(extended warranty) + Support helpline and troubleshooting for 3 years post initial warranty period. - Device should be reliable and have a long supported life (ideally not less than 10 years) - Product must fit within available lab space; floor plan max area 2m x 2m OPTIONAL/DESIRABLE: - The ability to also use other types of "standard" HPF specimen carriers, such as copper tubes (0.4-0.9 mm diameter), sapphire disks, other, etc. - Able to fit into or Retrofittable into a Correlative Light-Electron Microscopy (CLEM) workflow and/or employ the "Waffle" method for a cryo on-grid thinning workflow. Live cell imaging is not needed (freezing sample seconds after an "event") as part of the initial requirement. In the future we may want to freeze a sample and observe it with light and electron microscopy but freezing the sample at a specific time is likely not needed. - Reliable stock of consumables/specimen carriers for purchase AWARD The University anticipates initially awarding for; - Device manufactured, delivered into the lab, installed, commissioned and tested by supplier; to be in a fully operable state - User training - 1 year full parts and labour warranty - Parts and labour extended service for 3 years post warranty The University welcomes suppliers providing details of their enhanced service offerings for comparison. INSTALLATION SURVEY: - Initial measurements have been provided for entrance ways and available floor space above but these are approximations - The University will take no liability if a supplier subsequently discovers they cannot deliver or install their solution without changes to the building fabric; in such circumstances the University may at its discretion cancel the award and award to the next-ranked supplier - Giving reasonable notice (and subject to any submission deadline) suppliers may request the opportunity to conduct a single site survey prior to submitting their bid and/or finalising the contract post-award, providing the University and Supplier can agree a mutually convenient date and time. We encourage suppliers to take this opportunity. MANUFACTURING DEADLINE Unless otherwise agreed or offered by the University suppliers must meet a deadline to manufacture and deliver the winning machine, and install+ commission it, by no later than end June 2026.

Options: Purchase of sundries, additional service and machine extensions may be undertaken with the winning bidder via the Negotiated Procedure Without Prior Call For Competition

Renewal: Duration estimate reflects; Initial term consisting of 1 year warranty and 3 years extended service (4 years) + the option to extend service for a further 4 years, to give a total potential term of approximately 8 years post-device delivery
