Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 50 mm are intended for microbiological and analytical laboratory applications. The membranes consist of cellulose nitrate (cellulose mixed ester) and support colony count determination, particle testing, microscopy and sterility tests. This unit is supplied as 1000 pieces with a net weight of 1,140 kg, giving a high-count pack for busier workflows. Membrane filters from manufacturer Sartorius are available in cellulose nitrate as well as cellulose acetate or regenerated cellulose, with configuration choices such as grid markings or a hydrophobic edge depending on the selected article. The 0,45 µm pore size together with the 50 mm diameter matches common laboratory filtration hardware used in quality control and research. Specifications state a non-sterile status, allowing laboratories to define sterilisation or handling steps as needed. Cellulose nitrate mixed-ester membranes in this size are a practical format for colony enumeration and particle checks. The 1000-piece pack supports continuous sampling and higher-throughput microbiology programmes.
This article is part of Carbohydrates & sugars, in Biochemicals & reagents.

Questions about CN green - dark green, sterile, 0.45 m
What is this article?
CN green - dark green, 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 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.
