Description
Cellulose nitrate (CN) membrane filters in 47 mm diameter with 0,8 µm pore size are classic laboratory discs for microbiological and particulate work. Manufactured from cellulose nitrate / mixed cellulose ester (CN, MCE), they support colony counting, particle examination, microscopy preparation and related filtration steps where a uniform microporous surface is required. This variant is non-sterile and is intended for applications that do not demand pre-sterilised membranes, or where the user applies their own sterilisation protocol. The 0,8 µm rating balances retention with practical flow for many aqueous samples, while the standard 47 mm format fits common filter holders and funnels. Supplied in packs of 100 pieces from manufacturer Sartorius, the membranes give laboratories a consistent consumable for routine QC, environmental monitoring support and general microfiltration tasks. CN/MCE chemistry is widely used because it wets readily and provides a clear background for colony or particle visualisation when grids or plain surfaces are selected in the broader product family. A dependable choice for structured membrane filtration workflows in research and industrial laboratories.

Questions about CN gray - white, sterile, 0.8 m
What is this article?
CN gray - white, sterile, 0.8 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.
