OpenSPR-Instrument

Overview

OpenSPR is the world’s only benchtop surface plasmon resonance (SPR) instrument. It provides high quality, label-free interaction analysis for a fraction of the cost of existing solutions. Our unique nano-structured sensor surface uses localized SPR (LSPR) to deliver repeatable, highly sensitive kinetic data.
