Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 47 mm are laboratory membranes made from cellulose nitrate, also described as cellulose mixed ester (CN, MCE). These non-sterile membrane filters are intended for colony count determination, particle testing and microscopy in microbiological and analytical work. Laboratories can select unsterile membranes with or without a grid and with or without a hydrophobic edge, matching common filtration holders and counting practices. The defined 0,45 µm pore size supports routine sample preparation steps where retained material is examined after filtration. Each pack contains 100 pieces, which suits recurring quality-control and research throughput. From manufacturer Sartorius, the 47 mm format aligns with standard funnels and manifolds used in membrane filtration workflows. Cellulose nitrate mixed-ester construction provides the handling behaviour expected for classical aqueous filtration protocols in microbiology reagent applications, helping teams keep filtration steps consistent across serial analyses without altering the stated non-sterile supply format.

Questions about CN white -black HE, non-sterile, 0.45
What is this article?
CN white -black HE, non-sterile, 0.45 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.
