Nalgene Vacuum Filter, Cellulose Nitrate Membrane, Sterile, 0.2 µm, 75 mm, 500 mL/1000 mL
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.
- Nalgene Rapid-Flow membrane support system provides fast flow and high throughput
- Upper chamber separates from receiver for easy access to filtrate
- Leak-proof screw cap eliminates pH shift in receiver bottle to provide longer life for stored fluids
- Receiver bottle is an ideal filtrate storage vessel
- Upper chamber of filter units is clearly marked with pore size, membrane type, catalog number, lot number and expiration date for traceability
- Pad-less membrane support minimizes foaming of proteinaceous samples
- Non-pyrogenic and non-cytogenic
- CN membrane with green collar for easy identification of correct membrane type
- Gamma radiation-sterilized and individually wrapped for a 5-year sterile shelf life
