Nalgene Vacuum Filter, PES Membrane, Sterile, 0.2 µm, 50 mm, 150 mL/150 mL

Nalgene Vacuum Filter, PES Membrane, Sterile, 0.2 µm, 50 mm, 150 mL/150 mL

Thermo Scientific Nalgene Rapid-Flow disposable Filter Units with PES (polyethersulfone) membrane provide the last line of defense against cell culture contamination. Low protein binding PES membranes with low extractables are the best choice for sterile filtration of cell culture media, serum, additives and buffers. Asymmetric PES membranes and exclusive Rapid-Flow support plate design provide fast flow rates and high throughput for increased filtration efficiency. NOTE: For laboratory use only. Not for in vitro diagnosis or parenterals. Included: Polystyrene cover; graduated upper chamber and storage bottle; integral membrane filter; cellulosic-plugged side arm; quick-disconnect tubing adapter.
  • Filter cup unscrews from storage bottle for easy access to filtrate
  • Leak-proof screw cap closure eliminates pH shift in storage bottle for longer life of stored media
  • Upper chamber of filter units is clearly marked with pore size, membrane type, catalog number, lot number and expiration date (except 115 mL size)
  • Pad-less membrane support minimizes foaming of proteinaceous samples
  • Non-pyrogenic and non-cytotoxic
  • PES membrane with blue collar
  • Gamma radiation-sterilized and individually bagged for a 5-year sterile shelf life
