Description
PORAFIL PE membrane filter with a pore size of 0,20 µm and a diameter of 47 mm provides a defined PET membrane disc for laboratory filtration and sample preparation. Made from polyethylene terephthalate (PET), the membrane offers a consistent porous matrix for particle retention, clarification and related analytical workflows. Supplied in packs of 100 pieces, the 47 mm format matches widely used filter holders and funnels in research and quality-control environments. This PORAFIL PE membrane comes from manufacturer Macherey-Nagel and is specified with a 0,20 µm pore width to support reproducible fine filtration. The filters are non-sterile and therefore intended for general laboratory use rather than sterile processing. PET material properties and the intermediate 47 mm diameter make them a practical choice when moderate filtration area and a fine pore rating are required. They suit routine vacuum or pressure filtration of aqueous and compatible samples where controlled membrane geometry and reliable pack quantities are important for daily laboratory operations.
This article is part of Membrane filters, in Filtration.

Questions about PORA PE, PW:0,20 µm, d: 47 mm
What is this article?
PORA PE, PW:0,20 µm, d: 47 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.
