Description
neoChoice membrane filter in cellulose nitrate (CN), white, without grid, non-sterile, combines a 0,45 µm pore size with a 25 mm diameter for analytical and microbiological filtration. Cellulose nitrate membranes are a standard medium in this field and are well suited to microbiological examination of water, food and beverages within the pH range 4–8. The membrane material is specified as cellulose nitrate / mixed cellulose ester (CN, MCE), offering the retention characteristics expected for routine laboratory filtration at this pore rating. Maximum thermal stability is given as 130 °C. Supplied as plain white discs without grid markings and in non-sterile condition, the filters are packed in units of 100 pieces from manufacturer neolab - Labor. They support particle and microbial retention steps in quality-control and research workflows where a 25 mm CN membrane at 0,45 µm is specified, including sample preparation and microbiological analysis under the stated pH window.
This article is part of 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 Lab consumables.
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.
