The Unique Benefits of Affinité's Innovation


No more complex instrumentation or manipulations. Just a streamlined workflow on injections accessible to beginner and advanced scientists. You are a 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 microfluidic for cartridge integration. Modular optical design for system integration of biosensing platforms. 


SPR at centralized platform is expensive in time and money for most applications. For less than a year in maintenance cost on large SPR devices, you can have our instrument at your bench to get rapid answers on your protein interactions or scout optimal SPR conditions.



I come from 7+ years running a clinical research lab. I ran a wide range of clinical tests on biological samples such as ELISA, PCR, electrophoresis but not SPR. However, it did not stop me from being highly proficient in the technique. The P4SPR was just easy to learn despite my lack of direct knowledge. Basically, after a half-a-day training, I was autonomous within a day and very comfortable with data within a week. It took me about a month to perform an analytical validation for a new target and validate it with clinical samples. I believe it was faster to develop our assay compared to ELISA.

"A number of academic research labs in the university have taken advantage of the ultra-portable unit to carry out SPR based binding experiments in their own labs with publishable results."
