Beschrijving
Cellulose nitrate (CN) membrane filters are non-sterile laboratory membranes intended for colony count determination, particle testing and microscopy. They consist of cellulose nitrate (cellulose mixed ester) and belong to a family of membranes that also includes cellulose acetate and regenerated cellulose. Laboratories may select non-sterile membranes with or without a grid and with or without a hydrophobic edge, depending on the plating or inspection method in use. This presentation contains 1000 pieces, suited to higher-throughput microbiological and particle-analysis workloads. Filters of this kind from manufacturer Sartorius are used when colonies or retained particles are evaluated in standard laboratory procedures. Net weight is 0,386 kg and gross weight is 0,386 kg per pack. The product originates from Germany (Lower Saxony) and falls within microbiology reagent categories. Typical tasks include colony enumeration after membrane filtration, particle checks on process samples and microscopic examination of material collected on the membrane surface during quality-control testing.

Questions about CN white - black, non-sterile, 0.2 m
What is this article?
CN white - black, non-sterile, 0.2 m is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Media.
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.
