Use Nalgene™ Rapid-Flow™ Sterile Disposable Filter Units with CN (Cellulose Nitrate) membrane for sterile filtration, prefiltration or clarification of buffers and other aqueous solutions when protein binding is not a concern. Filter units have a green collar for easy identification of correct membrane type. Clearly marked with pore size, membrane type, catalog number, lot number and expiration date for traceablility. 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. Not intended for post-filtration storage of media (use Rapid-Flow products if media storage is required).
