Discover OpenSPR™

High Quality

Get robust real-time interaction analysis

Attention to detail at the nano scale
  • OpenSPR uses a highly sensitive nanogold coating as the sensor substrate (traditional SPR uses planar gold films)
  • Real-time interaction analysis: OpenSPR has an ultra-stable and sensitive optical spectroscopy system combined with flow injection
  • User-friendly software: OpenSPR is controlled by our custom OpenSPR Software Platform via a PC or Mac* over USB (automatic set-up procedure with convenient features like injection markers) *On virtualization
  • Performance and stability – We have implemented advanced algorithms for real-time data fitting to reduce noise
