The 32 detection spots in the Sierra SPR-32 system are addressed by the use of 8 injection needles. When using the Individual Needle Control (INC) feature, researchers can choose any combination from 1 to 8 needles. INC optimizes the performance, flexibility and scope of applications possible, while saving time and materials when throughput is not the main requirement.
Up to four buffers can be used simultaneously in the instrument. The ability to evaluate different pH‘s, ionic strength, detergent or solvent concentration and the effect of co-factors or inhibitors in a single assay yields simpler, optimized assays that ultimately increase throughput and productivity.
