Nalgene* Rapid-Flow* Sterile Disposable Bottle Top Filters with SFCA Membrane

Thermo Scientific* Nalgene Rapid-Flow Sterile Disposable Bottle Top Filters with SFCA Membrane fit Nalgene filter receiver bottles (#455-series) or standard glass media bottles.
Surfactant-Free Cellulose Acetate (SFCA) membranes have lower extractables than standard cellulose acetate (CN) membranes. If you use CA for filtration of media or other cell culture fluids, you owe it to your cells to switch to cleaner, safer Nalgene SFCA.

  • Side-arm with quick-disconnect tubing adapter for easy bottle top changes
  • Non-cytotoxic and non-pyrogenic
Surfactant-free cellulose acetate membranes (SFCA)

  • Low protein binding, excellent flow rates, little or no loss of specific proteins
  • No wetting agents to affect sensitive cell culture lines
  • Much lower extractables than standard CA membranes makes SFCA a better choice for cell culture
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.
