Nalgene 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. 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.

CN Membrane

  • Triton-free
  • Green collar for easy identification of correct membrane type

Upper Chamber

  • Separates from receiver for easy access to filtrate
  • Clearly marked with pore size, membrane type, catalog number, lot number and expiration date for traceability

Receiver Bottle

  • Leakproof screw cap eliminates pH shift in receiver bottle to provide longer life for stored fluids
  • An ideal filtrate storage vessel

Other Features

  • Padless membrane support minimizes foaming of proteinaceous samples
  • Non-pyrogenic and non-cytogenic
  • Gamma radiation-sterilized and individually wrapped for a five-year sterile shelf life

115mL Sizes

  • Compact filter units for quick filtration of 50 to 100mL of fluid
  • Unitary construction with non-separable upper and receiver components
  • Side arm on receiver
  • Not intended for post-filtration storage of media (use Rapid-Flow products if media storage is required)
  • 115mL sizes do not have Rapid-Flow support plate design

50 or 75mm diameter membrane, polyethylene adapter, and quick-disconnect tubing adapter. Each pack of 500 and 1000mL units includes 12 glass fiber prefilters. 115mL does NOT come with sterile polyethylene leakproof closure that lets you use the receiver for filtrate storage. Use a larger size for this feature.

0.45um size conforms to Specification 909A, B and C of APHA Standard Methods, 16th ed.; EPA certification sheets included.
