Description
PORAFIL PE membrane filter with a pore size of 0,20 µm and a diameter of 37 mm is a circular laboratory membrane intended for defined particle retention and sample clarification. The membrane material is polyethylene terephthalate (PET), giving a stable polymeric structure suited to analytical filtration, particle removal and general sample-preparation steps. Each pack contains 100 pieces, supporting routine throughput in research, quality-control and process laboratories that use 37 mm filter holders. These discs form part of the PORAFIL PE range from manufacturer Macherey-Nagel and are specified with a uniform 0,20 µm pore width for reproducible retention behaviour. The non-sterile format is appropriate for standard bench work where aseptic packaging is not required. PET chemistry and the compact 37 mm diameter make the filters a practical consumable for aqueous and compatible solvent filtrations when a fine pore rating and consistent membrane geometry are needed. They integrate readily into common vacuum or pressure filtration setups used across life-science and industrial laboratories.
This article is part of Membrane filters, in Filtration.

Questions about PORA PE, PW:0,20 µm, d: 37 mm
What is this article?
PORA PE, PW:0,20 µm, d: 37 mm is the article on this page. Luminix Health distributes Macherey-Nagel 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.
