Description
Cellulose nitrate membrane filters with a diameter of 50 mm and a pore size of 0,45 µm are sterile mixed cellulose ester (MCE) discs for microbiological filtration and colony work. The membranes combine cellulose nitrate and cellulose acetate and are white with a black grid that improves contrast for easier colony reading. Each filter is sterile and individually packaged, supporting aseptic handling in routine microbiology. The 0,45 µm porosity suits bacterial retention and particulate capture on the membrane surface during standard filtration procedures. Supplied in a pack of 100 pieces from manufacturer Labbox, these filters fit common membrane filtration assemblies used for microbiological testing and quality control. The grid pattern aids quantitative evaluation by increasing visibility against the white background. With a net pack weight of 0,105 kg, the set is practical for laboratory stock. These MCE membranes are intended where sterile, contrast-enhanced cellulose-based filters are required for microbiology applications.
This article is part of Membrane filters, in Filtration.

Questions about Cellulose nitrate membrane Ø 50 mm, Sterile, 0,45 µm, 100 pcs
What is this article?
Cellulose nitrate membrane Ø 50 mm, Sterile, 0,45 µm, 100 pcs is the article on this page. Luminix Health distributes Labbox 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.
