Description
Cellulose nitrate (CN) membrane filters with 0,45 µm pore size and 25 mm diameter are unsterile membranes made from cellulose nitrate (mixed cellulose ester, CN, MCE). They support colony counting, particle testing and microscopy in microbiological and analytical workflows. Users can select variants with or without grid as well as with or without hydrophobic edge to match specific protocol needs. The filters deliver consistent retention characteristics suited to routine quality-control and research filtration steps. Packaged as 100 pc(s), these membranes from manufacturer Sartorius integrate readily into standard laboratory filtration setups. Their cellulose-based composition provides reliable handling and clear colony visualisation when used with appropriate culture media. Suitable for particle analysis and microbial enumeration tasks, the membranes help maintain reproducible results across repeated tests. Net weight is 0,038 kg per unit pack, facilitating straightforward inventory management in busy lab environments.

Questions about CN white - black, non-sterile, 0.45 m
What is this article?
CN white - black, non-sterile, 0.45 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.
