Description
Cellulose acetate membrane filter 0,22 µm, 25 mm is a white, unsterile membrane disc intended for laboratory filtration tasks that require a clearly defined pore size and diameter. The 0,22 µm pore rating supports fine clarification and particulate retention in routine sample work, while the 25 mm diameter fits widely used small-scale filter holders in analytical and research laboratories. Packaged as 100 pieces, the discs provide a convenient stock level for repeated preparation steps and method development. Supplied from manufacturer filtraTECH, these cellulose acetate membranes are unsterile and therefore positioned for general laboratory filtration where sterility is not stated as a requirement. Cellulose acetate is a familiar membrane material for aqueous solutions and many mild media encountered in everyday lab practice. Users choose this 0,22 µm / 25 mm format when dimensional consistency and material identity are the primary selection criteria for non-sterile membrane filtration on the bench.
This article is part of Membrane filters, in Filtration.

Questions about Cellulose acetate membrane filter 0,22µm, 25 mm
What is this article?
Cellulose acetate membrane filter 0,22µm, 25 mm is the article on this page. Luminix Health distributes filtraTECH 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.
