Description
Membrane filter mixed cellulose ester, 0,45 µm, non-sterile, black with grid, is a round laboratory membrane disc for filtration and visual evaluation tasks. With a 50 mm diameter and 0,45 µm pore size, the mixed cellulose ester membrane supports particle retention and sample assessment where a dark background improves contrast. The printed grid on the black surface aids colony counting and systematic inspection of retained material under standard bench lighting. Supplied non-sterile as round filters, the format suits workflows that apply separate sterilisation or that do not require a sterile membrane at point of use. A pack of 100 pieces supports routine laboratory throughput in quality control, environmental monitoring, and general membrane filtration. These filters from manufacturer Hahnemühle are positioned for methods that specify a black, gridded MCE disc at 0,45 µm. The mixed cellulose ester matrix offers familiar handling for everyday membrane work, while the compact 50 mm round geometry fits common filter holders and funnels used in particulate and microbiological preparation steps.
This article is part of Membrane filters, in Filtration.

Questions about Membrane filter Mixed cellulose ester ,0.45 µm, non-sterile, black, grid ,Discs
What is this article?
Membrane filter Mixed cellulose ester ,0.45 µm, non-sterile, black, grid ,Discs is the article on this page. Luminix Health distributes Hahnemühle 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.
