Most 2 ml deep well plates really only provide 1.80 to 1.90 ml of liquid capacity per well. Porvair Science’s now has a 96-well round deep well plate that actually delivers 2 ml of liquid capacity in automation-compatible SLAS/ANSI footprint. The common wall provides a 45-mm height limit ensuring compatibility with most plate handling equipment. Certified as RNase/DNase-free, they contain no measurable contaminants that could leach out and affect the sample, and irradiated versions are also available. A matching thermoplastic elastomer cover provides friction-free sealing for transport, shipping and short-term storage. The plates can also be heat-sealed for long-term storage. Porvair Sciences Ltd.
