Thermo Scientific Nalgene Rapid-Flow Sterile Disposable Filter Units with CN (Cellulose Nitrate) membrane are ideal for sterile filtration, pre-filtration or clarification of buffers and other aqueous solutions when protein binding is not a concern. Nalgene CN membranes are Triton-free. Individually wrapped. All units have a five-year sterile shelf life.
Included: 75 mm diameter membrane, polyethylene adapter, and quick-disconnect tubing adapter. Each pack of 500 and 1000 mL units includes 12 glass fiber pre-filters. All sizes except 115 mL supplied with sterile polyethylene leakproof closure that lets you use the receiver for filtrate storage.
NOTE: For laboratory use only. Not for in vitro diagnosis or parenterals. CN membranes are best used for filtration of buffers and general lab solutions. We do not recommend CN for filtration of cell culture fluids because it has high protein binding characteristics. Use PES or SFCA for cell culture media, serum, additives, etc.
