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 Blue®Carriers
no-tip magnetic bead wash

No-tip, fast AMPure
magnetic bead separation for NGS library preparation.
Discover why leading NGS labs are switching from liquid handlers to BlueWashers for magnetic bead spearation.

Since winning SLAS and MipTec new product awards in 2015, Blue® Washer has become the new standard for media change in cellular assays and no-tip magnetic bead separation in NGS library prep. Most top 25 pharma companies and top clinical diagnostics labs now use Blue® Washers to obtain better cellular assay data and cut run time and save tips for NGS library prep. 

Blue® Washer's
Blue® Dispenser modules can be configured to dispense in 96, 384, and 1536w plates from 4 or 7 shared liquid inputs and up to 3 dedicated liquid inputs. Dedicated inputs eliminate need for flushing when switching liquids.
