Using centrifugation instead of aspiration to remove liquids from microplates, BlueWasher achieves residual volumes 10x lower than conventional plate washers, reducing background and improving z' for typical adherent cell-based assays by 0.1 to 0.3, leading to fewer missed active compounds and fewer false positives to re-screen.  Chemists and bioinformaticians love the BlueWasher!
