Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,65 µm and a diameter of 50 mm are laboratory membrane discs for filtration and microbiological examination. They consist of cellulose nitrate, also described as cellulose mixed ester (CN, MCE), and are intended for aqueous sample handling in research and quality-control environments. Typical uses include colony count determination, particle testing, microscopy and sterility-test workflows that depend on defined membrane retention. The filters are supplied non-sterile in a pack of 100 pieces, so users can follow their own preparation or sterilisation procedures as required. Offered by manufacturer Sartorius, each pack has a net weight of 0,100 kg. The 50 mm format matches standard filter holders, while the 0,65 µm pore rating supports retention of particles and microbial structures at that specification. These CN membrane filters integrate into particle checks, clear filtration steps and sample preparation routines where mixed cellulose ester performance is preferred without pre-sterilised packaging, supporting consistent handling across routine microbiology laboratory filtrations.

Questions about CN white, sterile, 0.65 m
What is this article?
CN white, sterile, 0.65 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.
