Description
PORAFIL PE membrane filter with a pore size of 0,40 µm and a diameter of 47 mm is a laboratory membrane disc for filtration, clarification, and particle-retention applications. Manufactured from polyethylene terephthalate (PET), the membrane is supplied non-sterile in packs of 100 pieces. The 0,40 µm pore width provides a defined cut-off suitable for many analytical sample-preparation steps, while the 47 mm diameter fits widely used filter holders and vacuum or pressure filtration assemblies. PET construction offers the mechanical behaviour expected of polymer membrane discs during loading, filtration, and disposal. These PORAFIL PE filters from manufacturer Macherey-Nagel support routine laboratory workflows where a standard 47 mm format and medium-fine porosity are specified. Non-sterile supply matches general-purpose use rather than aseptic processing. Explicit pore-size and diameter data simplify selection against method requirements, holder geometry, and solvent-compatibility assessments already established in the laboratory. The 100-piece pack supports continuous series work without frequent restocking of individual discs.
This article is part of Membrane filters, in Filtration.

Questions about PORA PE, PW:0,40 µm, d: 47 mm
What is this article?
PORA PE, PW:0,40 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.
