Description
PORAFIL MV membrane filters, white, with a pore size of 0,20 µm and a diameter of 50 mm are laboratory membrane discs intended for filtration tasks that specify a fine 0,20 µm retention level. The plain white MV membrane format supports sample clarification, particle retention and routine preparation steps on standard holders matched to the 50 mm diameter. Each pack contains 50 pieces, giving a practical working quantity for everyday bench use. Physical data list a net weight of 0,03 kg and a compact pack footprint suited to organised laboratory storage. These non-sterile discs from manufacturer Macherey-Nagel are positioned for general laboratory filtration rather than aseptic processing. The defined pore width of 0,20 µm helps laboratories maintain consistent cut-off behaviour across repeated filtrations, while the white surface assists visual checks of retained material. PORAFIL MV filters in this size integrate into existing membrane workflows without changing holder geometry, making them a straightforward choice wherever a 50 mm, 0,20 µm white membrane is required.
This article is part of Membrane filters, in Filtration.

Questions about PORA MV, white, PW:0,20 µm, d: 50 mm
What is this article?
PORA MV, white, PW:0,20 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.
