Description
PORAFIL MV membrane filter is a white membrane filter with a pore size of 0,45 µm and a diameter of 220 mm. This disc-format membrane is intended for laboratory filtration work where a defined pore rating and a large active filter area are required, for example in particle retention and sample clarification steps. The white membrane surface supports straightforward visual assessment of retained material during use. Each unit is supplied in a pack of 25 pieces, giving a convenient stock quantity for routine analytical and preparative workflows. Offered as the PORAFIL MV type from manufacturer Macherey-Nagel, the filter is specified as non-sterile and is therefore suited to general laboratory handling rather than aseptic procedures. The 220 mm diameter fits larger filter holders and higher-volume sample processing compared with smaller discs, while the 0,45 µm pore width provides a clearly stated retention rating for compatible liquid samples. Consistent diameter and pore specifications help maintain reproducible set-up from run to run. These membrane filters belong to the standard laboratory membrane-filter category and integrate into filtration assemblies matched to the stated dimensions.
This article is part of Membrane filters, in Filtration.

Questions about PORA MV, white, PW:0,45 µm, d: 220 mm
What is this article?
PORA MV, white, PW:0,45 µm, d: 220 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.
