Thermo Scientific™ Nalgene™ Rapid-Flow™ Sterile Disposable Filter Units

Bottle Top Filter Units and Storage Bottles Only Nalgene has the unique Rapid-Flow™ membrane support system that uses an evenly-spaced array of columns to provide greater membrane stability – resulting in faster flow and higher throughput of fluids – perfectly suited for sterile filtration and clarification of 50-1000 mL of cell culture media, serum, additives and buffers.

Rapid-Flow Selection Guide

Making the Right Selection
Select the right pore size

– 0.1 micron for sterile filtration and Mycoplasma removal

– 0.2 micron for sterile filtration

– 0.45 micron for clarification

– 0.8 micron for prefiltration and clarification

Select the right capacity Choose from 50 mL, 115 mL, 150 mL, 250 mL, 500 mL, 1000 mL capacity filter units and bottle top filters.
Select the right membrane diameter Options include 50 mm, 75 mm and 90 mm diameter. Wider membranes mean faster flow and more throughput so you don’t have to reach for a second filter for difficult-to-filter fluids. Only Nalgene has 90 mm diameter membranes in 500 mL and 1000 mL size filter units and bottle top filters.
Select the right membrane

– PES (polyethersulfone) is the ultimate cell culutre membrane with low protein binding so there is less chance of removing critical protein from your media. It is hydrophylic, so no external wetting agents or surfactants are needed, resulting in low extractables. And, it’s fast so you spend less time waiting.

– SFCA (surgactant-free cellulose acetate) containes none of the wetting agents founf in standard CA (cellulose acetate), and also has lower protein binding than standard CA. If you use CA for medie filtration you owe it to your cell lines to switch to SFCA; it’s only available in Nalgene filter units and bottle top filters.

– CN (cellulose acetate) is ideal for filtering water, buffers and other aqueous solutions when protein binding is not a concern or if you want to remove extraneous protein.

– NYL (nylon) membranes are tough, alcohol resistant and have low levels of extractables. Choose them for filtering alcoholic solutions.

Select the right media storage bottle Nalgene storage bottle cap design prevents gas exchange and maintains pH of stored media for up to two weeks. Nalgene storage bottles are available in 150, 250, 500 and 1000 mL sizes, separately or as an integral part of all Nalgene filter units.
Select the right quality Every lot is Nalgene-Certified to be sterile, non-cytotoxic, non-pyrogenic, and to have passed strict performance tests. We guarantee it!

Thermo Scientific™ Nalgene™ Rapid-Flow Sterile Disposable Filter Units – PES Membrane

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.

  • Asymmetric PES membrane plus unique Rapid-Flow support plate design provides fast flow and high throughput of fluids for increased filtration efficiency
  • 0.2 μm units protect against bacterial contamination
  • 0.1 μm units also protect against Mycoplasma contamination

115 mL Sizes

  • Compact filter units for quick filtration of 50-100 mL of fluid
  • Unitary construction with non-separable upper and lower compartments
  • Not intended for post-filtration storage of media (use Rapid-Flow products if media storage is required)

† The term “leakproof” applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100 mm, 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 100 mm 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.
