Use Nalgene™ Rapid-Flow™ Sterile Disposable Filter Units with SFCA (Surfactant-Free Cellulose Acetate) membrane to conduct vacuum filtration and single-use biological work requiring sterile filtration, prefiltration or clarification of aqueous solutions in the lab or field. Surfactant-Free Cellulose Acetate (SFCA) membranes have lower extractables than standard (CA) membranes. Filter units have a Yellow collar for easy identification of correct membrane type. Clearly marked with pore size, membrane type, catalog number, lot number and expiration date for traceablility. Low extractables and naturally hydrophilic. Low protein binding, excellent flow rates, little or no loss of specific proteins. Contains no wetting agents to affect sensitive cell culture lines. Padless membrane support minimizes foaming of proteinaceous samples. Leakproof screw cap eliminates pH shift in receiver bottle to provide longer life for stored fluids. Non-pyrogenic and non-cytogenic. Gamma radiation-sterilized and individually wrapped for a five-year sterile shelf life.
