Description
Membrane filters, track-etched polycarbonate, with a pore size of 0,45 µm and a diameter of 25 mm, are disc membranes for laboratory filtration and separation work. The track-etched polycarbonate construction is intended for membrane-filter protocols where a defined 0,45 µm pore rating and a compact 25 mm format are specified. These filters suit general labware filtration, sample clarification, and separation steps that call for polycarbonate membrane discs in compatible holders. Pack size is 100 pc(s), giving a practical stock quantity for routine bench use. The 25 mm diameter supports small-volume assemblies and standard filter housings designed for this disc size, while the 0,45 µm pore size addresses common analytical and preparative filtration needs. Offered by manufacturer GVS, the membranes fall within filtration, water-related preparation, and broader membrane-filter categories used across research and quality-control laboratories. Each pack is a ready unit of 100 pieces for organised inventory. Approximate pack weight is 0,060 kg. Use follows normal laboratory membrane-handling practice for track-etched polycarbonate discs in filtration and separation workflows.
This article is part of Membrane filters, in Filtration.

Questions about Mem. filters, track-etched polycarbonate, Ø 25 mm, pore size 0.45 µm
What is this article?
Mem. filters, track-etched polycarbonate, Ø 25 mm, pore size 0.45 µm is the article on this page. Luminix Health distributes GVS 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.
