Sterile polystyrene 96 MicroWell Plates are ideal for fluorescence-based cell assays. The raised well rims reduce the risk of cross-contamination. Each non-toxic white or black plate is provided with clear lid. Black plates provide minimum background in fluorescence reading with minimum back-scattered light, while white plates provide maximum reflection and minimum auto-fluorescence and auto-luminescence. Each well has a suggested working volume of 0.2 mL and culture area of 0.33 cm2.
