Weighing molecules with light
A revolutionary new technology
Mass photometry is a revolutionary new way to analyze molecules. It enables the accurate mass measurement of single molecules in solution, in their native state and without the need for labels.
This approach opens up new possibilities for bioanalytics and research into the functions of biomolecules.

A new era in the analysis of biomolecules
A compact, bench-top instrument with minimum installation requirements.
Software automatically controls the acquisition process and performs mass analysis in minutes.
Measurements only require a few microliters of sample.
Intuitively interpret the mass distribution results without the need for any a priori knowledge.
About us
Refeyn was spun out of Oxford University in 2018 with the goal to make mass photometry available to the scientific community. Since then, we have been working tirelessly on our mission to realise the full potential of our award winning technology.
