These disposable filter units feature an inherently hydrophilic PES (polyethersulfone) membrane that exhibits extremely low protein binding, low extractable levels, and high flow rates.

Graduated upper chambers and receivers come in 115, 150, 250, 500, or 1000mL sizes and feature a side arm with a cellulosic vent plug and quick disconnect tubing adapter. The lot number, catalog number, membrane type, pore size, and expiration date are printed on the upper chamber of the 50mm, 75mm, and 90mm diameter filter units. All units have a blue collar and are certified sterile, noncytotoxic, and nonpyrogenic.
