Description
Polyethersulfone membrane filter 0,22 µm, 47 mm is a white, unsterile disc membrane intended for routine laboratory filtration work. With a defined pore size of 0,22 µm and a standard 47 mm diameter, it fits common filter holders and supports clarification and particle retention steps in aqueous and many solvent-compatible workflows. The polyethersulfone (PES) membrane material is widely used where consistent flow and chemical resistance are required in analytical and research settings. Each pack contains 100 pc(s), making the format practical for shared benches, method development, and recurring sample preparation. Supplied from manufacturer filtraTECH, these plain white discs arrive unsterile and are suited to protocols that do not demand pre-sterilised media. Typical uses include buffer and media filtration support, sample clean-up ahead of instrumental analysis, and general particulate control in quality-control or teaching laboratories. The compact 47 mm geometry simplifies handling, stacking, and storage while remaining compatible with standard vacuum and pressure filtration hardware used across life-science and chemical labs.
This article is part of Membrane filters, in Filtration.

Questions about Polyethersulfone membrane filter 0,22µm, 47 mm
What is this article?
Polyethersulfone membrane filter 0,22µm, 47 mm is the article on this page. Luminix Health distributes filtraTECH for laboratory use. It sits in Membrane filters, inside Filtration, in Consommables.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
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.
