Description
Polyethersulfone membrane filter 0,45 µm, 90 mm is a white, unsterile laboratory membrane disc for routine filtration work. With a defined pore size of 0,45 µm and a diameter of 90 mm, the filter supports clarification and particulate retention steps where a polyethersulfone (PES) membrane is specified. The plain white membrane presentation keeps visual inspection straightforward during loading and after use. Supplied in a pack of 100 pc(s), the format suits multi-sample series, method development, and day-to-day bench filtration without single-unit handling overhead. These membrane filters from manufacturer filtraTECH belong to standard labware assortments used across analytical, quality-control, and research environments that call for consistent disc geometry and a well-known polymer type. Polyethersulfone is widely selected when aqueous and many mild solvent streams need a stable polymeric barrier at the stated micron rating. Each unit is unsterile, so users apply their own sterilisation or aseptic handling protocols when a sterile workflow is required. The 90 mm diameter matches common filter holders and funnels of that size, helping laboratories standardise consumables across instruments and stations while keeping pore-size identification clear on the product label.
This article is part of Membrane filters, in Filtration.

Questions about Polyethersulfone membrane filter 0,45µm, 90 mm
What is this article?
Polyethersulfone membrane filter 0,45µm, 90 mm is the article on this page. Luminix Health distributes filtraTECH for laboratory use. It sits in Membrane filters, inside Filtration, in Lab consumables.
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.
