Description
Cellulose nitrate (CN) membrane filters with a pore size of 0,45 µm and a diameter of 47 mm are mixed cellulose ester membranes intended for colony counting, particle testing, microscopy and related quality-control filtration. The material is cellulose nitrate, also designated cellulose mixed ester (CN, MCE), a matrix widely used when effective microbial and particulate retention is required. Each unit pack comprises 100 pieces with a net weight of 0,107 kg, suited to series work in water purification testing, environmental contaminant checks and food content or quality-control workflows. The 47 mm diameter aligns with common analytical filter holders, while the 0,45 µm pore size supports fine retention tasks in routine microbiology. These membranes from manufacturer Sartorius form part of a CN filter offering that includes gridded or non-gridded styles and optional hydrophobic edges depending on method design. Scientific specifications list the product as non-sterile, so preparation remains under laboratory control. Manufactured in Germany (Lower Saxony), the filters serve microbiology reagent applications that need reproducible CN membrane performance at 0,45 µm across standard laboratory holders.

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 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.
