Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 50 mm are mixed cellulose ester membranes for microbiological and analytical filtration tasks. The filter material is cellulose nitrate, also known as cellulose mixed ester (CN, MCE), and the membranes are supplied non-sterile according to the product data. Typical uses include colony count determination, particle testing and microscopy, supporting sample work-up before incubation or optical evaluation. The 50 mm diameter fits larger filtration assemblies while the 0,45 µm pore rating addresses common retention needs in laboratory liquid handling. Packs of 100 pieces help maintain continuous availability for routine series and method development. These membranes from manufacturer Sartorius belong to the established cellulose nitrate / MCE family used across microbiology reagent workflows. Consistent material and geometry assist laboratories in standardising filtration steps for particle and microbial examination without introducing claims beyond the stated specifications and application scope.

Questions about CN white/black HE, sterile, 0.45, 100P
What is this article?
CN white/black HE, sterile, 0.45, 100P 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.
