Description
Bottle-top filters with PES membrane are ready-to-use plastic filtration units for vacuum filtration in the laboratory. Each unit combines a polyethersulfone (PES) membrane of 50 mm diameter and 0,2 µm pore size with a 150 ml upper capacity, supporting efficient bottle-top filtration of aqueous samples, media, and buffers. The PES membrane format is intended for routine clarification and particle removal where a defined pore size and compact membrane area are required. These filters fit standard vacuum bottle-top workflows and help avoid separate membrane handling during day-to-day filtration tasks. Offered in a pack of 12 pieces with a total weight of 1,020 kg, they suit laboratories that need consistent, single-use bottle-top units for repeated small-volume work. The 50 mm membrane and 150 ml reservoir balance filtration area with manageable sample volumes. Produced by manufacturer Nalgene, the units belong to ready-to-use plastic filtration systems used in vacuum technology and laboratory filtration applications. Clear pore-size and diameter specification supports straightforward selection for protocols that call for 0,2 µm PES bottle-top filtration at the 150 ml scale.

Questions about Bottle-top filters with PES-membrane, Ø 50 mm, pore size 0.2 µm, 150 ml
What is this article?
Bottle-top filters with PES-membrane, Ø 50 mm, pore size 0.2 µm, 150 ml is the article on this page. Luminix Health distributes Nalgene for laboratory use. It sits in Bottle-top & vacuum filtration units, inside Filtration, in Consommables.
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.
