Used in bacteriology, serology, molecular biology and other laboratory disciplines employing hemagglutination or complement fixation assays. Used for dilution screening of recombinant organisms. These sterile polystyrene, 96-well plates measure 86 x 128 mm. The wells have raised rims to reduce risk of cross-contamination. The lids have rings to control condensation during incubation. The beveled corners on the plates and lids prevent accidental reversal of the lid onto the plate. Wells are alpha numeric for easy identification. Stack conveniently and securely, with or without lids. Clone selection and replication are performed with a few simple movements using the transferable solid phase (TSP) unit (170-390-11).
