Description
Cellulose acetate membrane filter Type 12303 is a disc membrane intended for laboratory filtration of aqueous solutions, solvent mixtures and clarification tasks. The cellulose acetate medium combines high flow rates with solid thermal stability, supporting efficient processing in pressure filtration devices. It is compatible with aqueous media as well as oils, alcohols and other organic solvents commonly encountered in analytical and preparative workflows. These membrane filter discs from manufacturer Sartorius are supplied non-sterile in a pack of 25 pc(s), giving laboratories a practical quantity for routine clarification and solvent handling. Net weight is 0,040 kg per unit pack. The Type 12303 format is a well-established choice wherever reliable cellulose acetate performance is required for aqueous and mixed-solvent filtration without additional sterility claims.
This article is part of Membrane filters, in Filtration.

Questions about CA Membrane; 1.2 µm; 142mm; 25pk;n;st
What is this article?
CA Membrane; 1.2 µm; 142mm; 25pk;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.
