Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 47 mm are intended for colony count determination, particle testing, microscopy and sterility testing. The membranes consist of cellulose nitrate, cellulose mixed ester (CN, MCE) and are supplied in a pack of 100 pieces. Within this product family, sterile membranes are offered individually packaged or for dispensers, and users can select versions with or without grid as well as with or without a hydrophobic edge. These filters from manufacturer Sartorius provide the widely used 0,45 µm rating on a 47 mm disc that fits standard filtration set-ups in the microbiology laboratory. The pack has a net weight of 0,100 kg. Cellulose mixed ester membranes support clear visualisation of colonies and particles after filtration, making them a practical consumable for quantitative microbial enumeration and related microscopic assessment in quality-control and research workflows that rely on consistent membrane handling from sample to plate.

Questions about CN gray - white, sterile, 0.45 m
What is this article?
CN gray - white, sterile, 0.45 m is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Microbiologie.
A carbohydrate reagent is a sugar or a derivative, specified by identity, anomer where it matters, and purity. Hydrate and anhydrous forms change the mass. A culture-grade sugar and an analytical standard of the same name are different bottles.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
