Description
PORAFIL TE membrane filter is a white polytetrafluoroethylene (PTFE) membrane featuring a pore size of 0,45 µm and a large diameter of 220 mm. This laboratory membrane filter is suited to filtration steps that need chemical resistance together with a well-defined pore structure for sample preparation and particle retention. PTFE material supports handling of aggressive solvents and workflows in which fluoropolymer membranes are preferred. Available in a pack of 10 pieces from manufacturer Macherey-Nagel, the discs are practical for repeated use in analytical or preparative setups. The 0,45 µm pore width gives a clear performance specification, while the 220 mm diameter fits large-format filter holders used for higher-volume or broader-area filtration. White PORA TE membranes offer laboratories a reliable PTFE medium for aqueous and organic applications that demand inert membrane discs. They support research, quality-control, and general laboratory filtration where standardised large-diameter PTFE membranes are required in a multi-piece pack.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:0,45 µm, d: 220 mm
What is this article?
PORA TE, white, PW:0,45 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.
