Nalgene Vacuum Filter, PES Membrane, Sterile, 0.2 µm, 50 mm, 250 mL/250 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.
