The C.WASH automates the washing of micro-well plates using centrifugal force and can be used to streamline high-throughput screening in drug development and next-generation sequencing library preparation. The C.WASH removes liquids from well plates without needles or pipette tips for the non-contact washing of wells, ELISA assays and bead-based PCR purification. Unlike other plate washers, the C.WASH’s centrifugal design results in higher reproducibility, faster processing times, and reduced plastic waste.
