## Summary

Cambridge University Hospitals NHS Foundation Trust bought two AeroTrak+ A100-51 portable particle counters for use in the Cambridge Cellular Therapy Laboratory at JCBC, Cambridge. The supply includes instrument configuration, documentation and two protective carry cases. The equipment is for airborne particle monitoring, supporting work in the cellular therapy laboratory. The buyer is the NHS foundation trust; the equipment is delivered in Cambridge. This is a focused supply requirement for specialist particle-counting instruments and associated setup and documentation, rather than a general laboratory equipment or monitoring-services contract.

The procurement is complete and the contract has been awarded to Clean Air Technologies Limited. The contract was signed on 21 October 2026 and runs from 22 October 2026 to 21 January 2027. Its value is £27,275 excluding VAT (£32,730 including VAT). The requirement was handled as a below-threshold procurement; the specific procedure is recorded as unknown. There was one lot, covering the purchase of both counters and the associated configuration, documents and protective cases. The award is active and the contract is active. No evaluation criteria are stated in the procurement details.

This award shows that Cambridge University Hospitals requires portable particle-counting equipment for its specialist cellular therapy laboratory, including configuration and supporting documentation as well as protective transport cases. Suppliers best placed to compete for a similar requirement would be able to supply the specified AeroTrak+ A100-51 instruments or demonstrate an equivalent fit for airborne particle monitoring, and provide reliable setup and the required documentation. The two-unit requirement represents a focused equipment supply rather than a large-scale systems project. Clean Air Technologies Limited, an SME, was selected, showing that a specialist small supplier could fulfil the requirement. Credibility will depend on matching the laboratory’s equipment specification and delivering the complete supply package to the Cambridge site. The procurement used a below-threshold route.
