Description
Nalgene™ Rapid-Flow™ sterile disposable bottle top filters with PES membrane enable sterile filtration of cell culture media and sera in a convenient single-use format. Each unit combines a polyethersulfone (PES) membrane of 0,2 µm pore size with a 75 mm membrane diameter and a nominal volume of 500 mL, fitting bottles with a 33 mm neck. The PES membrane supports efficient flow while retaining microorganisms for sterile preparation of media and related solutions. These Thermo Scientific laboratory plastics filters are supplied ready to use as disposable bottle-top assemblies, reducing cleaning and cross-contamination risk between runs. Ideal for cell culture, media preparation, and routine sterile filtration workflows, they arrive in cases of 12 identical units for consistent laboratory stock. The Rapid-Flow design streamlines attachment to compatible receiver bottles and supports reproducible sterile filtration steps in research and production-support environments without additional hardware beyond standard bottle necks.

Questions about Nalgene™ Rapid-Flow™ Sterile Single Use Bottle Top Filters
What is this article?
Nalgene™ Rapid-Flow™ Sterile Single Use Bottle Top Filters is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Bottle-top & vacuum filtration units, inside Filtration, in Lab consumables.
A bottle-top filter or a vacuum filtration unit sits on a bottle and pulls a liquid through a membrane under vacuum. Pore size and membrane are the same choice as a syringe filter, at a larger area. A sterile unit is a stated claim. The bottle neck has to match.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
