Description
Cellulose nitrate (CN) membrane filters with an 8 µm pore size and 50 mm diameter are unsterile mixed cellulose ester discs intended for colony count determination, particle testing and microscopy. The membrane material is cellulose nitrate / cellulose mixed ester (CN, MCE), a classic choice for microbiological retention work where clear visualisation of colonies and particles is required. These non-sterile filters suit workflows in which the user controls subsequent handling or sterilisation steps. Offered in a practical pack of 100 pieces from manufacturer Sartorius, they fit standard 50 mm filtration holders used in quality-control, environmental and research laboratories. The relatively open 8 µm structure supports rapid throughput while retaining larger particles and microbial colonies for enumeration or microscopic examination. Net pack weight is 0,092 kg, making the unit easy to store and dispense at the bench. Select this CN membrane format when reliable particle and colony assessment on a 50 mm disc is needed without pre-sterilisation.

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 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.
