Description
neoChoice cellulose nitrate (CN) membrane filters are white, grid-free discs established as a standard medium for analytical and microbiological filtration. With a pore size of 0,45 µm and a diameter of 47 mm, these non-sterile membranes are well suited to microbiological analysis of water, food and beverages in the pH range 4–8. The material is cellulose nitrate / mixed cellulose ester (CN, MCE), combining familiar handling properties with dependable retention for routine colony and particle work. Maximum thermal stability is 130 °C. Supplied in packs of 100 pieces from manufacturer neolab - Labor, they support everyday filtration steps in food testing, environmental water analysis and related quality-control laboratories. The plain white surface without a printed grid keeps the membrane versatile for applications where grid lines are not required, while the 0,45 µm rating addresses common microbial retention needs. Consistent disc geometry aids mounting in standard 47 mm holders used across analytical and microbiological workflows.
This article belongs on Membrane filters, in Filtration.

Questions about neoChoice Membranfilter, Cellulose Nitrat (CN), weiß, ohne Gitter, unst
What is this article?
neoChoice Membranfilter, Cellulose Nitrat (CN), weiß, ohne Gitter, unst is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Membrane filters, inside Filtration, in Consommables.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
