Description
PORAFIL TE membrane filter is a white polytetrafluoroethylene (PTFE) laboratory membrane with a pore size of 0,20 µm and a diameter of 142 mm. Offered as a disc filter in the PORAFIL TE series, it supports membrane filtration tasks in analytical, process-support and research environments. The PTFE material is chosen where chemical resistance of the membrane is important, and the 0,20 µm pore size sets the retention level for fine filtration steps. Filters are white and non-sterile according to the manufacturer data, making them suitable for general laboratory use rather than sterile workflows. They are packed in units of 10 pieces, matching larger-diameter handling needs on compatible 142 mm filter holders. This membrane is available from manufacturer Macherey-Nagel as part of the PORAFIL TE membrane filter range. Specified diameter, pore width and polymer type allow clear matching to sample preparation, clarification and particulate-removal procedures that require PTFE. Uniform disc dimensions aid reliable seating in standard laboratory filtration assemblies used for routine work at this size.
This article is part of Membrane filters, in Filtration.

Questions about PORA TE, white, PW:0,20 µm, d: 142 mm
What is this article?
PORA TE, white, PW:0,20 µm, d: 142 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.
