Beschreibung
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 50 mm are intended for colony counting, particle testing and microscopy. The membranes are based on cellulose nitrate (mixed cellulose ester), with cellulose acetate and regenerated cellulose also represented in the wider filter programme. Selection covers membranes with or without grid markings and with or without a hydrophobic edge, so the format can be matched to counting or inspection needs. Packaged as 100 pieces from manufacturer Sartorius, these 50 mm discs suit standard filtration assemblies used in microbiology laboratories. The 0,45 µm pore size is appropriate for colony number determination and for particle checks prior to microscopic evaluation. Non-sterile supply according to the product data supports controlled laboratory handling rather than pre-sterilised single-use claims. Uniform disc geometry aids seating in common holders, and optional grids facilitate colony enumeration after incubation. This CN membrane filter pack provides a ready stock unit for routine quality-control and research filtration steps.

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