Refeyn pioneers analytical instruments that put AAV mass measurement capabilities within easy reach for scientists. Refeyn’s unique products measure the mass of individual AAV capsids, providing vital insights for AAV sample characterization and manufacturing process development.

Our instruments feature mass photometry technology, which uses light to weigh single particles in solution. It can measure AAV capsids as well as proteins, nucleic acids and complexes. Providing intuitive data in minutes, mass photometry enables scientists to optimize R&D processes and focus on innovation.

Refeyn’s mission is to transform analytical workflows in the life sciences, biopharma and beyond, using the power of light.
