Nalgene Rapid-Flow Sterile Bottle-Top Filters

These Thermo Scientific Nalgene Rapid-Flow Sterile Bottle-Top Filters include the Pall Life Sciences Supor machV polyethersulfone membranes for unsurpassed flowrate and performance.

Just screw the bottle-top filter onto a sterile vacuum-rated media bottle with a 33 or 43 mm neck size for direct vacuum filtration of your liquid samples. Choose Supor mach V membrane for faster filtration and the added benefits of PES membrane. PES membrane and surfactant-free cellulose acetate membrane both feature low protein binding and excellent flow rates. All feature a quick-disconnect tubing adapter on the collar. Radiation sterilized; certified non-cytotoxic; non-pyrogenic.

Order the 50 mm membrane for economy, or the 75 mm or 90 mm sizes for greater throughput. Membrane and pore size are clearly  marked on each filter. Reservoir capacities include 150, 500, and 1000 mL for use with standard media bottles.
