Description
Nalgene™ Rapid-Flow™ Sterile Disposable Bottle Top Filters with PES Membrane are designed for sterile filtration of cell-culture media and sera. These single-use bottle-top filters enable rapid, aseptic processing directly onto receiver bottles with a 33 mm neck. Each unit provides a 500 ml capacity, a membrane diameter of 33 mm and a pore size of 0,2 μm, supporting efficient clarification and sterilisation of sensitive biological liquids. The filters from manufacturer Thermo Scientific are supplied sterile and ready to use in packs of 12, eliminating cleaning and autoclaving steps. The Rapid-Flow geometry promotes high flow rates while maintaining membrane integrity for cell-culture and microbiology workflows. Disposable construction reduces cross-contamination risk and simplifies validation of sterile media preparation. Ideal for research and production laboratories that require consistent, ready-to-use filtration devices for media, buffers and sera, these bottle-top filters integrate smoothly into standard aseptic techniques and laminar-flow environments.

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.
