Description
Sartobran® P Midicaps® are sterile filtration capsules with a 0,2 µm pore size, intended for small-scale biopharmaceutical production. The units employ cellulose acetate membranes that support efficient sterile filtration while helping preserve high yield and the structural integrity of large proteins. Size 9 Midicaps® offer a practical capsule format for laboratory and pilot workflows where reliable membrane performance is essential. The 0,2 µm rating targets sterile-grade retention in protein-containing process streams, and the capsule construction facilitates use in compact filtration setups during development and small-batch campaigns. Each pack contains 4 pieces, making the product convenient for repeated process runs and method development. From manufacturer Sartorius, Sartobran® P Midicaps® address biopharmaceutical filtration tasks that demand careful handling of sensitive protein solutions. Cellulose acetate membrane technology underpins the filtration step for processes that require sterile filtrate and consistent product recovery. These capsules suit scale-down studies, small-batch manufacturing, and related applications in which controlled sterile filtration of large biomolecules remains a critical process requirement.

Questions about Sartobran P Midicaps 0.2m Size 9 4pc
What is this article?
Sartobran P Midicaps 0.2m Size 9 4pc is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Filter cartridges & capsules, inside Filtration, in Lab consumables.
A cartridge or a capsule is a pleated filter for a larger volume than a syringe filter, often in a housing or as a disposable capsule. Pore size, membrane and the connection, hose barb or sanitary, are the specification. It is the filter of a transfer line, not of a single injection.
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.
