Description
PP membrane filter discs 142 mm, 0,45 µm are polypropylene membrane filter discs intended for laboratory filtration work. Each disc measures 142 mm in diameter and features a defined pore size of 0,45 µm, supporting consistent particle retention in routine sample preparation and clarification steps. The polypropylene membrane material offers broad chemical compatibility for aqueous and many organic media commonly handled in research and quality-control laboratories. Supplied as a pack of 50 pieces, the discs arrive ready for use in standard filter holders matching the 142 mm format. Net and gross weight are both 0,16 kg per pack, with compact packaging dimensions that simplify storage and inventory handling. These membrane filter discs from manufacturer Berrytec belong to the laboratory materials category and carry UNSPSC classification 41104900. Origin is China. The combination of precise diameter, controlled pore size and practical pack quantity makes the discs a straightforward choice for laboratories requiring reliable polypropylene membrane filtration at the 0,45 µm level without unnecessary complexity.
This article is part of Membrane filters, in Filtration.

Questions about PP membrane disc filter 142mm, 0,45µm
What is this article?
PP membrane disc filter 142mm, 0,45µm is the article on this page. Luminix Health distributes Berrytec 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.
