Description
Polycarbonate membrane filters with a pore size of 0,4 µm and a diameter of 13 mm are black membrane discs intended for laboratory filtration and separation work. The polycarbonate membrane format supports particle collection, sample clarification and preparation steps where a defined pore geometry and compact disc size are required. Packs contain 100 pc(s), giving laboratories a practical stock quantity for routine filter changes and parallel experiments. The 13 mm diameter suits small filter holders and low-volume setups common in analytical and research benches. Black colouration improves visual contrast when inspecting retained material on the membrane surface after filtration. These membranes are offered from manufacturer MERCK MILLIPORE for standard labware filtration applications. Each pack weighs 0,023 kg, which simplifies inventory handling and shipment planning. Typical uses include clarifying suspensions, collecting particulates and preparing samples ahead of microscopic or instrumental analysis whenever a 0,4 µm polycarbonate membrane is specified. Consistent diameter and pore rating help keep filtration geometry reproducible across series of runs without introducing unnecessary variation in holder fit or retention behaviour.
This article is part of Membrane filters, in Filtration.

Questions about Polycarbonate-Membrane filters, black, Ø 13 mm, pore size 0.4 µm, 100 unit(s)
What is this article?
Polycarbonate-Membrane filters, black, Ø 13 mm, pore size 0.4 µm, 100 unit(s) is the article on this page. Luminix Health distributes MERCK MILLIPORE 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.
