The qSPR from Affinité Instruments is a cartridge-based, benchtop SPR instrument and is compatible with the KNX and KNX2 kinetics modules. Like the P4SPR, the qSPR enables SPR experiments with up to 4 samples concurrently in a small form factor.
For the qSPR, the SPR sensor and microfluidic channels are both encased in a cartridge. This approach enables safer handling of samples, such as blood, urine and saliva. Another feature, especially useful in biosafety labs, is the option to connect to the system remotely via Wi-Fi.
