Description
Cellulose acetate membrane filter Type 12303 is a laboratory membrane filter disc intended for aqueous and solvent-based filtration work. The cellulose acetate membrane combines high flow rates with thermal stability and is excellently suited for pressure filtration devices. It is compatible with aqueous solutions, oils, alcohols and other organic solvents, supporting common tasks such as filtration of aqueous solutions, solvent filtration mixtures and clarification. These performance characteristics make the Type 12303 format a practical choice wherever reliable throughput and broad solvent compatibility are needed in routine sample preparation. The filters are supplied in a pack of 100 pieces from manufacturer Sartorius. Net weight is 0,380 kg. In laboratory workflows the discs can be used for clarification steps ahead of analysis or further processing, and for handling mixed aqueous–organic media within the stated chemical compatibility. The membrane design focuses on flow performance and thermal behaviour under pressure-filtration conditions, giving a consistent option for general filtration duties in research, quality-control and process-support laboratories that require cellulose acetate discs of this type.
This article is part of Membrane filters, in Filtration.

Questions about CA membrane;1.2 µm;142mm;100pc;n;st
What is this article?
CA membrane;1.2 µm;142mm;100pc;n;st is the article on this page. Luminix Health distributes Sartorius 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.
