Description
PORAFIL TE membrane filter is a white polytetrafluoroethylene (PTFE) laboratory membrane with a pore size of 0,20 µm and a diameter of 220 mm. This large-format disc belongs to the PORAFIL TE membrane filter line and is intended for filtration applications in analytical and research laboratories that require a wider active area. PTFE provides the membrane polymer where chemical resistance is needed, while the 0,20 µm pore width defines the fine-filtration characteristic of the product. The filters are white and non-sterile as specified, supporting general laboratory handling rather than sterile processing. Packs contain 10 pieces, a convenient format for work with 220 mm holders and related filtration hardware. The membrane is supplied from manufacturer Macherey-Nagel within the PORAFIL TE range. Clear indication of diameter, pore size and material helps laboratories select the appropriate PTFE disc for sample clarification, solvent-compatible filtration steps or particulate retention. Consistent geometry of the 220 mm discs facilitates loading into compatible large-diameter filter assemblies used in routine laboratory practice.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:0,20 µm, d: 220 mm
What is this article?
PORA TE, white, PW:0,20 µm, d: 220 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.
