Beschreibung
Cellulose nitrate (CN) membrane filters in sterile presentation support colony counting, particle testing, microscopy and sterility testing. The sterile membranes are made of cellulose nitrate (mixed cellulose ester), cellulose acetate or regenerated cellulose and are available individually packed or configured for dispenser use. Selection covers sterile membranes with or without a grid and with or without a hydrophobic edge, so layout can be matched to counting grids and inspection methods. Offered as 1 piece from manufacturer Sartorius, this unit suits controlled microbiology workflows that require ready-to-use sterile membranes. Individually packaged sterile filters reduce preparation before filtration and help maintain aseptic technique during sample processing. Typical uses include microbial enumeration, particulate assessment and related quality-control checks alongside standard nutrient media and incubation steps. Net weight is 1,330 kg per unit as stated in the product data. Country of origin is Germany, supporting integration into established membrane filtration protocols in pharmaceutical, food and environmental testing laboratories.
This article is part of Carbohydrates & sugars, in Biochemicals & reagents.

Questions about CN white - black, sterile, 1.2 m
What is this article?
CN white - black, sterile, 1.2 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.
