Increase filtration efficiency. Thermo Scientific™ Nalgene Rapid-Flow disposable Filter Units with PES (polyethersulfone) membrane feature the exclusive Rapid-Flow support plate design, providing fast flow rates and high throughput. 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.

Polystyrene cover; graduated upper chamber and storage bottle (except 115 mL size); integral membrane filter; cellulosic-plugged side arm; quick-disconnect tubing adapter.
† The term “leakproof” applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100mm, after they are filled with water, inverted, withstand air pressure of 2psig for 2 minutes, and no water escapes;. b) Bottle/funnel/flask closure systems of larger than 100mm after they are filled with water, inverted for 15 minutes, and no water escapes. Note: these tests, using other liquids, may not yield the same results. To ensure safe usage, customers are advised to test Thermo Scientific Nalgene bottles and closures under conditions of their planned applications. Thermo Scientific Nalgene products are leakproof at ambient temperature and pressure when used with their Nalgene closures.
