Description
Polycarbonate membrane filters with a pore size of 0,4 µm and a diameter of 25 mm are black membrane discs for laboratory filtration and separation tasks. The polycarbonate construction provides a defined membrane structure suited to particle retention, sample clarification and related preparation workflows. Each pack supplies 100 pc(s), supporting regular laboratory consumption and multi-sample series. The 25 mm diameter matches widely used mid-size filter holders and offers a practical filtration area for routine aqueous or solvent-compatible steps where polycarbonate chemistry is preferred. Black membranes aid visual assessment of retained solids after filtration. These filters come from manufacturer MERCK MILLIPORE within the membrane-filter labware range. Pack weight is 0,070 kg, which assists stock control and logistics. Laboratories employ this format for clarifying suspensions, collecting particulates and preparing samples for downstream microscopic or instrumental work when a 0,4 µm cut-off and 25 mm disc geometry are specified. Uniform pore size and diameter support consistent holder fit and reproducible filtration geometry from run to run in research and analytical environments.
This article is part of Membrane filters, in Filtration.

Questions about Polycarbonate-Membrane filters, black, Ø 25 mm, pore size 0.4 µm, 100 unit(s)
What is this article?
Polycarbonate-Membrane filters, black, Ø 25 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.
