Beschreibung
Cellulose nitrate (CN) membrane filters are non-sterile laboratory membranes made from cellulose nitrate (mixed cellulose ester, CN/MCE) for colony counting, particle testing and microscopy. With a diameter of 47 mm, they fit standard filtration holders used in microbiological quality control and analytical work. The mixed cellulose ester material provides a consistent medium for microbial enumeration and particulate assessment on culture media or under the microscope. Non-sterile membranes can be selected with or without a printed grid and with or without a hydrophobic edge to suit method requirements. Offered in a pack of 100 pieces from manufacturer Sartorius, this format supports routine plating and inspection workflows in water, food and environmental testing laboratories. The filters are intended for laboratories that prepare and handle membranes according to their own procedures. At a net weight of 0,100 kg per pack, they integrate readily into everyday microbiology reagent stocks for colony count determination and particle examination.
This article is part of Carbohydrates & sugars, in Biochemicals & reagents.

Questions about CN gray-white,non-sterile,0.45m,47mm
What is this article?
CN gray-white,non-sterile,0.45m,47mm 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.
