Summary of the contracting process

Birkbeck, University of London bought a Refeyn TwoMP-MassFluidix (HC) mass photometer, a scientific instrument for detecting and analysing samples by mass. The specified TwoMP system measures masses from 30 kDa to 5 MDa, with stated precision of ±2% and mass error of ±5% for a single measurement. The procurement description also gives resolution figures of 25 kDa at 66 kDa and 60 kDa at 660 kDa, and a concentration range of 100 pM to 100 nM. The equipment is for delivery in the United Kingdom. The purchase is categorised as goods, specifically detection and analysis apparatus.

The procurement is complete: Refeyn Ltd was selected and the contract was signed. Birkbeck used a direct award, stating that Refeyn was the only supplier of the TwoMP-MassFluidix (HC) system. The award was dated 19 August 2026. The contract was signed on 14 September 2026 and runs from 15 September 2026 to 14 September 2029, with a possible maintenance extension to 14 September 2030. The contract and award value is £282,355.65. There is one lot, marked suitable for SMEs. Evaluation criteria are not stated in the process information.

This purchase shows demand at Birkbeck for specialist mass-photometry equipment capable of analysing a broad mass range and meeting the stated precision, error, resolution and concentration specifications. A credible competitor for a future requirement would need to supply an instrument with comparable analytical performance, together with the technical expertise to demonstrate that it meets laboratory needs. The direct award was justified on the basis that Refeyn was the sole supplier of this particular system, so competing suppliers would need to offer a distinct alternative that addresses the same research requirement rather than simply reselling the named equipment. The contract also includes a possible maintenance extension, indicating that ongoing servicing capability may strengthen a supplier’s fit for this equipment requirement.
