Varieties with Supor membrane (0.2 or 0.45 µm) is designed for sampling hot water (such as that found in hot loop WFI systems). Individually bagged to ensure protection until the time of use. Complies with pharmacopoeial requirements for membrane filtration testing applications. Easy squeeze access to retrieve the membrane reduces operator fatigue and the risk of repetitive motion injuries. Available in 100 mL and 300 mL capacities with a variety of pore sizes.
