Refeyn pioneers analytical instruments that put molecular mass measurement capabilities within easy reach for scientists. Refeyn’s unique products measure the mass of individual proteins, nucleic acids, complexes and viruses – providing vital insights for scientific discovery, R&D and therapeutics production. Our instruments feature mass photometry technology, which uses light to quantify the mass of single particles in solution without labels. Providing intuitive data in minutes, mass photometry helps scientists solve their research questions, 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.
