SPR laser scanning

Surface plasmon resonance (SPR) represents optical-based, label-free detection technologies for real-time monitoring of binding interactions between two or more molecules.

Tasowheel’s tailored rotation solution enables fast and accurate SPR scanning.  It is completely maintenance-free, preserving extreme motion accuracy unchanged throughout the SPR system lifecycle.
