Description
PORAFIL PE membrane filter with a pore size of 0,20 µm and a diameter of 50 mm is a polyethylene terephthalate (PET) membrane disc for laboratory particle retention and sample clarification. The PET membrane structure delivers a uniform pore network suited to analytical filtration, particulate control and general sample-preparation tasks. Packs of 100 pieces support continuous laboratory use with 50 mm holders and filtration assemblies. Belonging to the PORAFIL PE series from manufacturer Macherey-Nagel, these membranes are defined by a 0,20 µm pore width for fine, reproducible retention performance. They are supplied non-sterile for standard bench applications where sterile packaging is unnecessary. The 50 mm diameter offers a larger filtration area than smaller discs while remaining compatible with common laboratory hardware. Combined with PET chemistry and a tightly specified pore size, the filters serve research, industrial and quality-control laboratories that need dependable membrane consumables for aqueous and compatible solvent filtrations under vacuum or pressure.
This article is part of Membrane filters, in Filtration.

Questions about PORA PE, PW:0,20 µm, d: 50 mm
What is this article?
PORA PE, PW:0,20 µm, d: 50 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.
