Beschreibung
Cellulose mixed ester (CME) membrane filters with a pore size of 0,45 µm and a diameter of 25 mm are smooth disc membranes for laboratory filtration and separation applications. The mixed-ester membrane format is widely used for particle retention and clarification of aqueous samples in analytical, environmental, and quality-control laboratories. A smooth surface provides an even filtration field for general sample preparation, while the 0,45 µm pore rating delivers defined retention performance suited to routine laboratory protocols. Packs contain 100 pc(s) with a pack weight of 0,086 kg, offering a convenient stock unit for day-to-day filtration work. These CME membrane filters from manufacturer MERCK MILLIPORE are compatible with standard 25 mm filter holders and manifolds commonly found in research and industrial labs. The mid-size diameter balances effective filtration area with manageable sample volumes. Transport data reference UN number 3270. Positioned in the membrane-filter segment of filtration and separation labware, the discs support reliable integration into established laboratory workflows without special adapters or format changes.
This article is part of Membrane filters, in Filtration.

Questions about Cellulose mixed ester CME membr. filters, smooth, Ø 25 mm, pore size 0.45 µm
What is this article?
Cellulose mixed ester CME membr. filters, smooth, 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 Verbrauchsmaterialien.
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.
