Nalgene™ Rapid-Flow™ Bottle Top Filters with SFCA Membrane

By Nalge
Nalgene™ Rapid-Flow™ Bottle Top Filters with SFCA Membrane

Lower the number of extractables in your bottle-top filters by switching from standard cellulose acetate (CA) to Nalgene™ Rapid-Flow™ Sterile Disposable Bottle Top Filters with SFCA Membrane. These filters fit Nalgene™ filter receiver bottles (#455-series) or standard glass media bottles and have surfactant-free cellulose acetate (SFCA) membranes.

Bottle Top Filters are marked with catalog number, membrane type, pore size, lot number, and expiration date for easy traceability. Molded-in graduations provide quick visualization of sample volume. The side-arm with quick-disconnect tubing adapter allows for easy bottle top changes. Filters are non-cytotoxic and non-pyrogenic and are gamma radiation sterilized and individually bagged for 5-year sterile shelf life.

Surfactant-Free Cellulose Acetate Membranes (SFCA) are low protein binding with little or no loss of specific proteins. Excellent flow rates. No wetting agents to affect sensitive cell culture lines. Much lower extractables than standard CA membranes.

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