Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,2 µm and a diameter of 50 mm are laboratory membranes made from cellulose nitrate, cellulose mixed ester (CN, MCE). They support colony count determination, particle testing, microscopy and further filtration-based checks in microbiological and analytical laboratories. Scientific specifications list the membranes as non-sterile. Disc geometry of 50 mm combined with the 0,2 µm pore size addresses methods that require fine retention on a standard filter diameter. The pack supplies 100 pieces for regular testing series. These membrane filters from manufacturer Sartorius fit protocols calling for cellulose nitrate / mixed ester chemistry at the stated pore rating. Net weight is 0,113 kg and gross weight is 0,113 kg per unit. Origin is Germany in the Lower Saxony region. Typical use cases cover colony enumeration after filtration, particle inspection of process or product samples, and microscopic review of residues collected on the membrane surface during routine quality-control work.

Questions about CN white - black, sterile, 0.2 m
What is this article?
CN white - black, 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 Microbiology lab supplies.
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.
