Blue®Washer uses centrifugation to remove liquids from 96, 384 and 1536w plates, eliminating background and variability in assay data. Highly reproducible residual volumes 10x lower than conventional plate washers raise z' by 0.1-0.3 for typical cellular assays. Higher z' means more reliable compound profiles - fewer truly active compounds missed AND fewer false positives to re-screen.

Centrifugal Blue®Washer: Meet the new standard

​​Cellular assays

Blue®Bench is very easy to use and fits on single work space or under a hood (longitudinal configuration). Intuitive controls are fully integrated into the Blue®Washer interface. For stacked and lidded plates.
With a suite of magnetic carriers, Blue®Washer dramatically reduces run time and tip waste for magnetic bead assays. 
Blue®Washer's magnetic carriers retain magnetic beads during centrifugal evacuation, eliminating costly and time consuming liquid removal by automated liquid handlers. Adding a Blue®Washer to your ALH typically doubles ALH throughput while eliminating tip waste in separation and wash steps.
