Description
CN membrane filters with a 5 µm pore size and 90 mm diameter are laboratory membrane discs intended for filtration and separation work. The porosity supports retention of coarser particles and clarification steps prior to finer membrane filtration. Packs contain 25 pc(s), matching larger-diameter formats often used when higher throughput or wider filter area is required. The 90 mm disc geometry suits corresponding filter holders in vacuum or pressure assemblies found in analytical and research laboratories. These membranes are supplied from manufacturer SARTORIUS within a membrane-filter portfolio for labware filtration. A 5 µm rating addresses prefiltration, particulate reduction, and general membrane-based separation in sample preparation. Larger diameter increases the working surface while remaining specified for standard 90 mm laboratory hardware. Unit weight is given as 0,002 kg in the product data, consistent with thin membrane construction. Use cases align with filtration, water-related purification support, and membrane separation tasks employing CN media. Consistent pore size and diameter help laboratories keep consumable selection stable across repeated filtration series without redesigning holder arrangements.

Questions about CN membrane filters, 5 µm, 90 mm, 25 unit(s)
What is this article?
CN membrane filters, 5 µm, 90 mm, 25 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.
