Combinatorial chemistry, environmental and food technology applications often have stringent requirements for sample storage and transportation. To address these needs, Porvair offers high-quality, large-volume microplates that are produced under class 10,000 clean room conditions. Made from virgin polypropylene, each 24-well—10 ml—and 48 well—5 ml and 7 ml—plate doesn’t contain any contaminants that may leach out and affect the samples. The plates can be heat-sealed to enable high-integrity storage for prolonged periods at -80°C, and the wells are rectangular with a ‘v’ bottom to facilitate easy sample concentration and recovery. Available in sterile and non-sterile versions. Porvair Sciences Limited
