Rethinking surface plasmon resonance – The P4SPR™ is an everyday tool for researchers to quickly develop bioassays and undertake biomolecular interaction characterizations from the convenience of your lab bench.

The Unique Benefit's of Affinite's Innovation:

Simplicity

No more complex instrumentation/manipulations. Just a streamlined workflow on injections accessible to beginner and advanced scientists. You are 15 minutes away to getting real-time biosensing results. 

Versatility

Adaptable at many levels to address standard and innovative applications. Compact for benchtop and portable applications. Flexible microfluidics for cartridge integration. Modular Optical Design for system integration of biosensing platforms. 

Affordability

Large SPR capital equipment is expensive in both time and money for most applications. For less than a year in maintenance costs on large SPR devices, you can have the P4SPR benchtop instrument, allowing you to get rapid answers on your protein interactions or scout optimal SPR conditions. 


Affinité Instruments offers two Portable Surface Plasmon Resonance (P4SPR™) models for your specific needs.

P4SPR machine

Dual Inlet Model

Best for assay development

  • Triplicate sample channel measurement with reference channel 

  • Connect to Affinité’s injection loop side module for kinetics analysis

 

P4SPR machine

Quad Inlet Model

Best for intermediate screening

  • Simultaneous comparison of four different samples at once.  

  • Fewer chip consumable usage.
