Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 50 mm support colony counting, particle testing, microscopy and sterility testing applications. Manufactured from cellulose nitrate, also referred to as cellulose mixed ester (CN, MCE), these membranes provide a familiar filtration medium for microbiological and analytical laboratories. This variant is supplied in a pack of 1000 pieces, suited to higher-throughput or multi-user settings. The product line from manufacturer Sartorius includes options with or without grid markings and with or without a hydrophobic rim, so the membrane format can be aligned with the intended protocol. A 0,45 µm pore rating is widely used for retaining microorganisms and particles during membrane filtration, and the 50 mm diameter matches standard holders and funnels. With a net weight of 1,120 kg per pack, the bulk quantity remains practical to store under normal laboratory conditions. These CN membrane filters are appropriate for quality control, research and industrial microbiology tasks that depend on consistent mixed-ester cellulose discs for enumeration, particle checks and microscopic inspection.

Questions about CN white - black, sterile, 0.45 m
What is this article?
CN white - black, 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 Life Science & Microbiology.
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.
