Description
PORA PE membrane filters are laboratory membrane discs with a pore size of 5,00 µm and a diameter of 25 mm. According to the product data the medium is polyethylene terephthalate (PET), presented under the PORA PE designation for membrane filtration use. Packs contain 100 pieces, giving a convenient quantity for recurring sample work in analytical and research environments. The membranes are non-sterile and are intended for general filtration steps that call for a 5,00 µm pore width in a 25 mm format. The intermediate diameter suits a wide range of standard filter holders and small- to mid-volume setups. This variant comes from manufacturer Macherey-Nagel as part of the PORAFIL membrane filter portfolio sold as PORA PE. Net weight is listed at 0,02 kg per pack. Laboratories select such PET membranes when protocols specify particle retention or clarification consistent with the stated pore size. Uniform disc geometry supports reproducible mounting and handling across successive filtrations at 25 mm and 5,00 µm.
This article is part of Membrane filters, in Filtration.

Questions about PORA PE, PW:5,00 µm, d: 25 mm
What is this article?
PORA PE, PW:5,00 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.
