Beschreibung
Cellulose nitrate (CN) membrane filters with 8 µm pore size and 47 mm diameter are unsterile membranes intended for colony counting, particle examination and microscopy. Manufactured from cellulose nitrate (cellulose mixed ester), these filters support microbiological and analytical filtration procedures in research and quality-control laboratories. Available from manufacturer Sartorius in packs of 100 pieces, the membranes may be used with or without grid patterns and with or without hydrophobic edges to match specific protocol requirements. The 8 µm pores enable effective retention and visualisation of larger particles and microbial colonies on standard filtration apparatus. Non-sterile CN membranes integrate readily into routine workflows for sample analysis, particle testing and colony enumeration without prior sterilisation steps. A diameter of 47 mm ensures compatibility with common filter holders and funnels. Net weight per pack is 0,090 kg, offering a practical quantity for ongoing laboratory use. These membranes provide a dependable option for microbiology applications that demand consistent pore geometry and material performance.
This article belongs on Carbohydrates & sugars, in Biochemicals & reagents.

Questions about CN white -black HE, non-sterile, 8 m
What is this article?
CN white -black HE, non-sterile, 8 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.
