Description
Cellulose mixed ester CME membrane filters with a pore size of 0,65 µm and a diameter of Ø 90 mm are smooth membrane discs for laboratory filtration and separation. The larger 90 mm format suits setups that require a broader filtration area while retaining the defined 0,65 µm pore size of the CME membrane. Each filter is supplied with a smooth surface finish, supporting straightforward placement in compatible holders and general membrane filtration procedures. Pack size is 25 pc(s) and pack weight is 0,050 kg, giving a compact unit quantity for method development, batch work or controlled laboratory use. These cellulose mixed ester membranes are linked with UN number 3270 and belong to the membrane-filter category used in filtration, water purification, dialysis and separation workflows. Available from manufacturer MERCK MILLIPORE, the product brings together the stated CME material, smooth finish, pore size and diameter in a clear pack configuration for organised lab filtration tasks.
This article is part of Membrane filters, in Filtration.

Questions about Cellulose mixed ester CME membr. filters, smooth, Ø 90 mm, pore size 0.65 µm
What is this article?
Cellulose mixed ester CME membr. filters, smooth, Ø 90 mm, pore size 0.65 µm 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.
