The robotic autosampler is designed to maximize the performance and throughput of the 2SPR Surface Plasmon Resonance instrument. It is specifically designed for life science related applications and is excellently suited for use with SPR biosensors. Features include sample cooling (4°C) and metal-free biocompatible PEEK Fluidics. Minimal sample carryover and excellent repeatability ensure high quality, reproducible kinetic data.
The autosampler is extremely flexible: It has the capability to inject small volumes – down to 1 µL - when sample quantity is limited or large volumes – up to 1 mL - when long term equilibrium analysis is required. The sample loop and syringe sizes can be varied for micro to macro injections. The autosampler is compatible with 1.5 and 0.3 mL sample vials, 96 and 384 well plates.
