Beschreibung
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 50 mm are laboratory membranes for microbiological and analytical work. They are made of cellulose nitrate (cellulose mixed ester) and can be used for colony count determination, particle testing, microscopy and sterility tests. Each pack contains 100 pieces and has a net weight of 0,112 kg. These membrane filters from manufacturer Sartorius belong to a range that also comprises cellulose acetate and regenerated cellulose membranes; catalogue variants may include options with or without grid and with or without hydrophobic edge. The combination of 0,45 µm pores and 50 mm diameter supports use in standard filter holders and funnels for quality-control and research laboratories. Product specifications list the membranes as non-sterile, so users apply their own preparation protocols where required. Cellulose nitrate mixed-ester discs in this format are selected when a defined pore size and diameter are needed for colony enumeration and particulate assessment. The 100-piece pack suits routine microbiology benches and method set-up.
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 Mikrobiologie.
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.
