Description
PORAFIL PE membrane filter with a pore size of 0,40 µm and a diameter of 50 mm is a disc membrane for laboratory filtration and sample clarification. The membrane material is polyethylene terephthalate (PET), and the product is supplied non-sterile in packs of 100 pieces. A pore width of 0,40 µm delivers a defined retention characteristic for particle removal and preparative filtration steps, while the 50 mm diameter is compatible with corresponding filter holders and filtration hardware. PET membrane discs handle in the usual way during placement, filtration, and change-out. These PORAFIL PE membranes from manufacturer Macherey-Nagel are intended for general laboratory membrane filtration where sterile packaging is not required. Stated pore size and diameter allow straightforward matching to method specifications, holder size, and process volume. The 100-piece unit quantity supports repeated use across sample series in analytical, quality-control, and research settings. Selection of the 50 mm format with 0,40 µm porosity helps standardise filtration steps within established laboratory protocols.
This article is part of Membrane filters, in Filtration.

Questions about PORA PE, PW:0,40 µm, d: 50 mm
What is this article?
PORA PE, PW:0,40 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.
