Summary of the contracting process

Birkbeck, University of London procured a Refeyn TwoMP-MassFluidix (HC) system, a mass photometer for detecting and analysing particles and molecules. The equipment covers a mass range of 30 kDa to 5 MDa, with stated resolution of 25 kDa at 66 kDa and 60 kDa at 660 kDa. It provides mass precision of ±2%, mass error of ±5% for a single measurement, and a concentration range of 100 pM to 100 nM. The requirement is categorised as goods and classified as detection and analysis apparatus. Delivery is for the United Kingdom, for use by Birkbeck, University of London, based in London.

The procurement is complete and was awarded on 19 August 2026 to REFEYN LTD. It used a direct award because the buyer states that Refeyn Limited is the only supplier of the Mass Photometry TwoMP-MassFluidix (HC) System, citing technical reasons linked to a single supplier. The award value is £282,355.65 including all stated taxes. The contract period is 1 September 2026 to 31 August 2029, with a possible extension to 31 August 2030 for a maintenance contract extension. There is one completed lot, marked as suitable for SMEs. A contract signature was scheduled for 1 September 2026, and the standstill period was due to end on 28 August 2026.

This award indicates demand for specialist mass photometry equipment rather than general laboratory apparatus. Suppliers seeking to compete for comparable requirements would need to demonstrate that they manufacture, distribute or support systems with the stated mass range, resolution, precision, error tolerance and concentration range. The direct-award rationale shows that product ownership, technical uniqueness or exclusive distribution rights can be decisive, so credible competitors would need clear evidence of equivalent functionality and any rights required to supply and maintain it. The requirement also includes an ongoing maintenance element through the possible extension, making manufacturer-authorised servicing, technical support, calibration and lifecycle maintenance relevant capabilities. The completed lot was identified as suitable for SMEs, indicating that a specialist smaller supplier could be credible where it can meet the technical and support requirements.
