Description
CN membrane filters with an 8 µm pore size and 25 mm diameter are laboratory membrane discs intended for filtration and separation work. Each pack supplies 100 pc(s), giving a practical stock quantity for routine sample preparation, clarification, and particulate retention on the bench. The 25 mm format matches common small-scale filter holders used in analytical and research laboratories, while the 8 µm rating supports coarser retention steps where that pore size is specified. These CN membranes come from manufacturer Sartorius and are positioned within standard labware filtration ranges for membrane-based workflows. The stated pack weight is 0,002 kg, which keeps handling and storage straightforward for everyday laboratory use. Consistent diameter and pore geometry help maintain reproducible filtration setups when protocols call for CN media at 8 µm. Suitable for general laboratory filtration sequences linked to separation and water-related preparation tasks, the membranes are supplied as ready-to-use discs. Choose this 25 mm, 8 µm CN variant when your method requires that combination of material type, pore size, and diameter in a 100-piece pack.

Questions about CN membrane filters, 8 µm, 25 mm, 100 unit(s)
What is this article?
CN membrane filters, 8 µm, 25 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.
