About the Company

Refeyn

Bench-top mass photometry for single molecules

Refeyn specializes in mass photometry, a technique that measures the mass of single molecules in their native, unlabeled state. Its products are compact bench-top instruments coupled with automated software that enables rapid mass analysis from only a few microliters of sample. Researchers can obtain mass distributions in minutes without prior knowledge or labeling. The company differentiates itself through its native-state, label-free approach, user-friendly bench-top systems, and integrated software that streamlines data acquisition and interpretation, making advanced biomolecule analysis accessible to academic labs, research centers, and pharmaceutical companies. Refeyn aims to advance bioanalytics by providing practical mass measurement tools that uncover biomolecular properties and functions with minimal setup and sample requirements.
