Let our surface plasmon resonance solution simplify things for you - by getting you the high quality data you need, at your bench.

OpenSPR is the world's only benchtop SPR instrument. It provides high quality, label-free interaction analysis for a fraction of the cost of existing solutions.

OpensPR is user friendly and sets up in just minutes, so you can start generating data right away. Our unique nano-structured sensor surface delivers repeatable, highly sensitive kinetic data for proteins, antibodies, nucleic acids, and more. Get on rate, off rate, affinity, and specificity data all from the comfort of your own bench.
