About the company
Refeyn Inc., a foreign-owned for-profit organization based in Great Britain, sells mass photometry instruments and related analytical equipment to U.S. federal research agencies as a prime contractor on small-dollar purchase orders with no set-aside designation. The vendor operates exclusively as a prime (100% of recent awards) and does not subcontract or bid on government-wide vehicles or multiple-award schedules.
Refeyn's federal footprint centers on the supply of mass photometry instrumentation — purpose-built analytical devices that characterize biomolecules, viral proteins, and adeno-associated viruses at the molecular scale without labeling. Recent representative work includes a $219,055 purchase order from the National Heart Lung and Blood Institute (July 2023) for delivery of a Refeyn Twomp Mass Photometer to support viral protein characterization research in Portland, Oregon; a $210,582.50 purchase order from the National Institute of Standards and Technology (September 2022) for a Refeyn Twomp Mass Photometer System to advance molecular-scale materials standardization; and a $19,500 one-year service agreement with the National Institute of Allergy and Infectious Diseases (January 2023) for mass photometer instrument maintenance supporting biomolecule and viral research. The vendor also performs equipment installation and relocation services — a $9,360 purchase order from NIST (September 2026) for mass photometer instrument breakdown, transfer, and reinstallation at Gaithersburg, Maryland.
Customer concentration is evenly split across three agencies: the National Institute of Allergy and Infectious Diseases (3 awards, $313 thousand combined potential value), the National Heart Lung and Blood Institute (3 awards, $273 thousand combined potential value), and the National Institute of Standards and Technology (2 awards, $220 thousand combined potential value), accounting for 100% of the award portfolio. Activity is sparse — one award in 2021, one in 2022, two in 2023, one in 2024, and one in 2026 — with combined potential value across all eight awards of $805 thousand and 100% of that value obligated. Only one award faces recompete in the next twenty-four months ($9 thousand combined potential value). Refeyn competes in full-and-open procurements without small business set-asides, positioning itself as a specialized equipment vendor rather than a services integrator or systems contractor.
