Introducing qSPR™, world's first cartridge-based benchtop SPR

Core Technology​​

Basic thin film SPR found in most benchtop devices capable of detection in complex media such as serum, plasma, cell lysates, or wastewater. 

Biosafety Design​​

Controlled process from injection to sample analysis in an enclosed cartridge. Ideal for quick infectious disease testing or assay development inside a small biosafety cabinet.

Rapid Data Processing

Intuitive software providing key data for biosensing and protein interaction characterization in real time. 

Quad Inlet Model
  • Simultaneous comparison of four different samples at once.  

  • Fewer chip consumable usage.

  • Thin film-based SPR disposable cartridge

  • Motorized cartridge sealing and release

  • Dimensions: 267 x 210 x 102 mm

  • Weight:  < 1.6 kg. 

  • Sensitivity:  2750 nm/RIU

  • Resolution : 1 micro RIU

  • Dynamic range: 1.33 to 1.39 refractive index unit

  • Coefficient of variation on signal: < 0.6%

  • Polychromatic light source

  • PyQt control graphic user interface 

  • Compatible with TraceDrawer™


With P4SPR, we were able to establish optimal immobilization conditions of SARS-CoV-2 spike and nucleocapsid within 2-3 SPR runs. Having the device at our bench also really helped comparing our SPR results against ELISA.
