Description
Sartopure® PP3 Midicaps® 50 µm Size 8 are high-performance encapsulated polypropylene fleece filters intended for efficient particle retention in small-volume production-scale and pilot biopharmaceutical processes. The 50 µm fleece medium provides robust particle retention and high dirt-holding capacity, enabling strong throughput even when particulate burden is elevated. All-polypropylene construction ensures a low extractables profile and maximal product recovery, while low unspecific binding contributes to elevated product yield. This Midicaps® format combines effective chemical compatibility with reliable operational performance for clarification and related particle-control steps. Capsules from manufacturer Sartorius are ideally suited for small-scale production applications that demand consistent prefiltration behaviour in a compact encapsulated housing. Each unit is offered in packs of 4 pc(s), facilitating straightforward deployment on pilot and limited-volume lines. The encapsulated polypropylene design simplifies installation and supports high product recovery versus formats with higher hold-up or binding. Net weight is 0,720 kg and gross weight is 1,252 kg according to the stated specifications.
This article is part of Filter cartridges & capsules, in Filtration.

Questions about Sartopure PP3 Midicaps 50m Size 8 4 pc
What is this article?
Sartopure PP3 Midicaps 50m Size 8 4 pc 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.
