Description
Cellulose nitrate membrane filters measuring 47 mm in diameter with a pore size of 0,20 µm are white discs printed with a black grid for microbiological applications. They are supplied sterile and individually packaged, ready for immediate use in colony enumeration, water microbiology and related filtration tasks. The fine 0,20 µm porosity supports effective retention of microorganisms while the contrasting grid aids accurate visual counting under standard laboratory lighting. A pack of 100 pieces provides ample stock for routine quality-control and research workflows. These membranes fit common filtration holders and manifolds used in clinical, environmental and industrial laboratories. Produced by manufacturer Labbox, the filters combine cellulose nitrate construction with sterile single-unit packaging to maintain aseptic conditions until the moment of use. Net weight of the unit is 0,134 kg. The product is suited to laboratories that require consistent pore performance and clear colony contrast on a gridded white surface.
This article belongs on Membrane filters, in Filtration.

Questions about Cellulose nitrate membrane Ø 47 mm, Sterile, 0,20 µm, 100 pcs
What is this article?
Cellulose nitrate membrane Ø 47 mm, Sterile, 0,20 µm, 100 pcs is the article on this page. Luminix Health distributes Labbox 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.
