Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 47 mm are mixed-ester membranes for microbiological and analytical filtration. The material is cellulose nitrate / cellulose mixed ester (CN, MCE), chosen for effective retention and strong microorganism recovery in routine laboratory work. Typical uses include colony counting, particle testing, microscopy and sterility-testing workflows, together with environmental contaminant checks, water purification testing and food content quality control. Each unit is supplied as a pack of 1000 pc(s), which suits higher sample throughput and fewer reorder cycles. These membranes from manufacturer Sartorius are aimed at users who need a consistent 0,45 µm rating on a 47 mm format compatible with standard filtration funnels and monitors. Gridded or non-gridded styles and optional hydrophobic edges form part of the wider CN membrane offering, so counting and microscopy protocols can be matched as required. Net weight is 0,890 kg. CN/MCE chemistry remains a practical standard wherever clear colonies and dependable particle capture are needed in water, food and environmental QC laboratories.

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.
