Description
PORAFIL PE membrane filter with pore size 0,20 µm and diameter 25 mm is a laboratory filtration membrane for particle retention and sample clarification in analytical and preparative workflows. Specified as a PORAFIL PE disc, it is produced from polyethylene terephthalate (PET) and supplied non-sterile for general laboratory use. The 0,20 µm pore width supports fine particulate removal and preparation of samples ahead of sensitive instrumental measurements. A diameter of 25 mm suits standard filter holders and medium-volume assemblies commonly employed in chemistry and life-science laboratories. Each pack contains 100 pieces, enabling convenient replenishment for multi-user benches and method-development work. These membrane filters from manufacturer Macherey-Nagel belong to the PORAFIL PE range and are intended where consistent pore geometry and PET chemical compatibility are required. Because the filters are not sterile, users should apply appropriate sterilisation or aseptic handling when sterile conditions are necessary. The 100 pc(s) unit supports economical stocking for routine filtration across quality-control and research laboratories.
This article is part of Membrane filters, in Filtration.

Questions about PORA PE, PW:0,20 µm, d: 25 mm
What is this article?
PORA PE, PW:0,20 µm, d: 25 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.
