Description
Filter units with PES membrane are ready-to-use plastic filtration units intended for laboratory vacuum and bottle-top filtration. This variant features a PES membrane of 50 mm diameter, a pore size of 0,45 µm and a 250 ml capacity, offering a defined membrane area and volume for clarifying and general sample preparation steps. The format integrates with common bottle-top filter systems used across research and analytical laboratories that apply vacuum technology for filtration. A pack contains 12 pc(s), which is practical for regular bench consumption. Stated pack weight is 1,360 kg. Produced by manufacturer Nalgene, the units belong to the category of ready-to-use plastic filtration units for filtration by means of bottle-top filters and systems. Selecting the 50 mm diameter with 0,45 µm pores and 250 ml volume allows laboratories to match membrane geometry and working volume to established methods without redesigning the setup. The PES membrane and multi-unit packaging support consistent day-to-day filtration practice where a coarser pore size relative to 0,2 µm formats is specified by the protocol.

Questions about Filter units with PES-membrane, Ø 50 mm, pore size 0.45 µm, 250 ml, 12 unit(s)
What is this article?
Filter units with PES-membrane, Ø 50 mm, pore size 0.45 µm, 250 ml, 12 unit(s) 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.
