Mass Photometry

Weighing molecules with light


One assay format delivering multiple results

A revolutionary new technology

Mass photometry is a revolutionary new method of analyzing 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.
