Description
EZ-Pak membrane filter (CME) provides a mixed cellulose ester membrane for controlled laboratory filtration and colony enumeration. The 0,45 µm pore size and 50 mm diameter, combined with a black gridded surface, give strong visual contrast for counting light-coloured colonies and retained material. Packaged as 600 pc(s) in the EZ-Pak configuration, the discs support efficient serial filtration in water microbiology, environmental monitoring, and routine quality-control laboratories. CME membranes wet evenly and handle consistently on standard filtration equipment, helping maintain uniform sample processing across large sample sets. Offered by manufacturer MERCK MILLIPORE, this black-grid variant is chosen when background contrast is critical for readout accuracy. The format suits professional filtration and separation workflows that demand defined pore geometry, stable disc dimensions, and rapid access to multiple membranes without interrupting analytical sequences.
This article is part of Membrane filters, in Filtration.

Questions about EZ-Pak membrane filter (CME), 0.45 µm, 50 mm, black, grid, 600 unit(s)
What is this article?
EZ-Pak membrane filter (CME), 0.45 µm, 50 mm, black, grid, 600 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.
