Description
Cellulose nitrate membrane filter, Ø 47 mm, sterile, pore size 0,45 µm is a mixed cellulose ester (MCE) membrane made from cellulose nitrate and cellulose acetate for microbiological filtration and colony enumeration. The white disc features a black grid that heightens contrast and simplifies colony counting after incubation. Filters are sterile and supplied in individual packaging to maintain aseptic conditions until use. With a 0,45 µm pore size and 47 mm diameter, the membranes match widely used holders and protocols for water, beverage, and environmental microbiology where standard bacterial recovery on gridded MCE is required. A pack of 100 pieces from manufacturer Labbox (BRANCHIA) gives laboratories a convenient stock of ready-to-use sterile discs. Net weight is approximately 0,120 kg per pack. These membranes support routine membrane filtration workflows that depend on clear grid visibility and single-use sterile presentation rather than bulk non-sterile stock.
This article is part of Membrane filters, in Filtration.

Questions about Cellulose nitrate membrane Ø 47 mm, Sterile, 0,45 µm, 100 pcs
What is this article?
Cellulose nitrate membrane Ø 47 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.
