Beschrijving
Cellulose nitrate (CN) membrane filters are unsterile laboratory membranes made of cellulose nitrate / cellulose mixed ester (CN, MCE), with a pore size of 1,2 µm and a diameter of 25 mm. They are intended for colony count determination, particle testing and microscopy in routine microbiological and analytical work. Users can choose unsterile membranes with or without a grid and with or without a hydrophobic edge, allowing the format to match counting, inspection or sample-preparation protocols. Supplied in packs of 100 pieces from manufacturer Sartorius, these discs suit filtration steps ahead of colony enumeration or microscopic evaluation. The mixed-ester composition and defined 25 mm geometry support consistent handling on standard filtration setups. Whether applied to particle examination or colony-count workflows, the membranes provide a practical CN/MCE option for day-to-day laboratory filtration and inspection tasks where unsterile membrane media are specified.
This article belongs on Carbohydrates & sugars, in Biochemicals & reagents.

Questions about CN white - black, non-sterile, 1.2 m
What is this article?
CN white - black, non-sterile, 1.2 m is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Media.
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.
