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:
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.
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.
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.
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
Quad Inlet Model
Best for intermediate screening
Simultaneous comparison of four different samples at once.
Fewer chip consumable usage.
