Description
Cellulose nitrate (CN) membrane filters are intended for colony counting, particle analysis and microscopy in microbiological laboratory workflows. Presented as Microsart® e.motion membranes, they are designed for use in the Microsart® e.motion filter dispenser and are sealed in a specially developed individual sterile pack without interleaving paper. The distinctive folding of each single package keeps the membrane correctly positioned during handling and transfer to the filtration setup. These membranes from manufacturer Sartorius can also be used together with Sartorius nutrient pad sets for culture-based testing. Supplied in a pack of 300 pc(s) with a net weight of 0,397 kg, they support routine membrane filtration where rapid, consistent membrane presentation from a dispenser is required. The CN format is well suited to colony enumeration and particle examination methods that rely on clear membrane handling and reliable filter placement. Select this configuration when dispenser-compatible, individually packed cellulose nitrate membranes are needed for microbiological quality-control and analytical work.

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