Blue®Washer uses centrifugation to remove liquids from 96, 384 and 1536w plates, eliminating background and variability in assay data. Highly reproducible, low residual volumes < 0.3 µl/ well 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.

Blue®Washer immediately improves screening economics without complex assay or automation changes, delivering unparalleled ROI and boosting drug discovery productivity.
Magnetic carrier for non-contact magnetic bead wash

Since winning SLAS and MipTec new product awards in 2015, Blue®Washer has rapidly become the new standard for media change and cell wash in cellular screening. Most top 25 pharma companies now use Blue®Washers to obtain better assay data (z') to reduce false positive and false negative results and deliver more meaningful compound profiles to chemists.

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 more than triples ALH throughput while eliminating tip waste in separation and wash steps.
