Label-Free Protein Binding with Real-Time SPR Sensing

Three Features Why P4SPR is the Future

Direct Detection

Core technology (Kretschmann configuration SPR) capable of direct detection in complex samples such as serum, plasma and blood for little to no sample preparation

Multi-Channel Testing

Four-channel design providing background-corrected, triplicate sample data for precise and accurate results every time


Proprietary optical design packaged in a compact, book-size device for robustness and low maintenance


Affinité’s innovations are deployed in research areas such as bioanalytical sciences, environmental monitoring, material science and more.

Although we have a state-of-the-art SPR, we use the P4SPR with graduate students to teach SPR and perform rapid testing.

The first time I saw the P4SPR I was amazed by its small footprint. This device really addresses the lack of accessibility and cost barrier of current SPR options for academic users.

Les étudiants ont eu l’opportunité de manipuler quelques instruments, dont le P4SPR qui n’a laissé personne indifférent. Ce qui a mis tout le monde d’accord c’est la rapidité de l’acquisition des résultats, la mobilité de l’appareil et surtout la simplicité d’utilisation.

Le P4SPR est utilisé depuis plus de 5 ans avec les étudiants au bac de chimie pour enseigner les biocapteurs. Le système à résister aux conditions extrêmes que les étudiants imposent à chaque semaine.

The flexibility and modularity of the system is key for us. We were able to adapt the P4SPR to integrate electrochemistry and fluorescence spectroscopy in parallel with SPR to create a unique multi-analytical system fitting our research needs.
