            • Marked with catalog number, membrane type, pore size, lot number and expiration date for easy traceability
            • Gamma radiation sterilized and individually bagged for a 5-year sterile shelf life
            • Molded-in graduations for easy visualization of sample size
            • Side-arm equiped with quick-disconnect tubing adapter for easy change between filters
            • Non-cytotoxic and non-pyrogenic

            Polyethersulfone (PES) membranes:

            • PES is the best membrane for cell culture fluids. It has the lowest protein binding to maintain protein balance, and the lowest extractables to maintain media purity
            • The asymmetric PES membrane plus unique Rapid-Flow support plate design provide fast flow and high throughput of fluids for increased filtration efficiency
            • Use 0.2 μm membranes for sterile filtration, 0.45 μm membranes for fluid clarification and particle removal


            Polystyrene graduated chamber; Blue color-coded collar with cellulosic vent plug side arm and quick-disconnect tubing adapter; 50, 75, or 90 mm diameter membranes; bottom screw threads for attachment to bottles with 33 or 45 mm neck sizes.
