Description
PORAFIL MV membrane filters, white, are laboratory membrane filters with a pore size of 0,20 µm and a diameter of 47 mm. They serve particle retention and sample clarification tasks in analytical and research environments that require a defined fine pore structure. The white membrane surface helps operators monitor retained material during filtration. Each unit is supplied as a pack of 50 filters, convenient for series work and standard operating procedures. These PORAFIL MV discs from manufacturer Macherey-Nagel match widely used 47 mm filter holders and vacuum filtration assemblies for aqueous and compatible media. The 0,20 µm rating supports fine filtration ahead of sensitive measurements or downstream processing. The larger 47 mm diameter provides greater filtration area for higher sample loads while keeping handling straightforward. Well suited to quality control, environmental monitoring, and general laboratory filtration where reproducible pore size and a ready pack quantity are essential.
This article is part of Membrane filters, in Filtration.

Questions about PORA MV, white, PW:0,20 µm, d: 47 mm
What is this article?
PORA MV, white, PW:0,20 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.
