Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,8 µm and a diameter of 50 mm are laboratory membrane discs for filtration and microbiological examination. They are made from cellulose nitrate, also known as cellulose mixed ester (CN, MCE), and support aqueous sample handling in research and quality-control settings. Application areas include colony count determination, particle testing, microscopy and sterility-test workflows that rely on membrane retention. The filters are supplied non-sterile in a pack of 100 pieces, giving laboratories flexibility to apply their own preparation protocols. Available from manufacturer Sartorius, each pack has a net weight of 0,100 kg. The 50 mm diameter fits common filter holders, while the 0,8 µm pore size provides a defined retention rating for particles and microbial structures. These CN membrane filters suit particle checks, clear filtration steps and sample preparation routines that call for mixed cellulose ester performance without pre-sterilisation, with a consistent disc format for serial work in microbiology laboratories.

Questions about CN white, sterile, 0.8 m
What is this article?
CN 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 Life Science & Microbiology.
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.
Which category should I open next?
