Description
CN membrane filters with a pore size of 3 µm and a diameter of 47 mm are laboratory membrane discs designed for filtration and separation work. The pack contains 100 pc(s), giving laboratories a convenient stock of standard mid-size membranes for recurring filtration tasks. With a 47 mm diameter, the discs match common filter holders used in analytical sample preparation, particle retention and general clarification steps. The CN membrane construction supports routine laboratory filtration where a defined 3 µm pore size is required by the method or protocol. Listed unit weight is approximately 0,002 kg, reflecting a lightweight consumable that is simple to store and handle at the bench. These CN membrane filters from manufacturer Sartorius sit within the membrane filters segment of laboratory filtration and separation products and are chosen when both the 3 µm pore rating and the 47 mm format are specified. They suit quality-control, research and routine sample-handling environments that rely on consistent membrane geometry and straightforward integration into existing filtration hardware without additional process redesign.
This article belongs on Membrane filters, in Filtration.

Questions about CN membrane filters, 3 µm, 47 mm, 100 unit(s)
What is this article?
CN membrane filters, 3 µm, 47 mm, 100 unit(s) 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.
