Description
Cellulose mixed ester (CME) membrane filters with a pore size of 0,45 µm and a diameter of 25 mm are gridded disc membranes intended for laboratory filtration and separation tasks. The mixed-ester composition supports particle retention and sample clarification in analytical and quality-control environments. Gridded marking on the membrane surface assists visual evaluation, colony counting, and documentation after filtration, while the 0,45 µm pore size provides a defined retention level for routine aqueous sample work. Each unit pack holds 100 pc(s) and weighs 0,101 kg, giving laboratories a practical quantity for repeated use on standard equipment. These CME membrane filters from manufacturer MERCK MILLIPORE match common 25 mm holder and manifold formats used across research, environmental, and industrial laboratories. The 25 mm diameter offers a useful filtration area for typical sample volumes without excessive membrane consumption. Associated transport classification includes UN number 3270. As part of the membrane-filter range within filtration and separation labware, the product is ready for direct use in established laboratory filtration setups.
This article is part of Membrane filters, in Filtration.

Questions about Cellulose mixed ester CME membr. filters, gridded, Ø 25 mm, pore size 0.45 µm
What is this article?
Cellulose mixed ester CME membr. filters, gridded, Ø 25 mm, pore size 0.45 µm is the article on this page. Luminix Health distributes MERCK MILLIPORE for laboratory use. It sits in Membrane filters, inside Filtration, in Consommables.
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.
