Filter cartridges & capsules

A capsule is a ready-to-use filter with its own housing: you connect it, filter and dispose of it, with no housing to clean or validate. That suits small batches, pilot work and sterile steps, for example the sterile-filtration capsule, 0.2 µm, size 9, 4 pieces. A cartridge is the filter element alone and goes into a reusable stainless-steel housing. Cartridges come in standard lengths of 10, 20 and 30 inch, such as the polypropylene depth-filter cartridge, 8 µm, 10 inch, and pay off for larger, recurring volumes.

A prefilter takes out the bulk of particles so the final filter does not clog. Polypropylene depth filters, rated nominally in µm, are the usual choice, for example the polypropylene depth-filter capsule, 8 µm, size 0 or the depth-filter cartridge, 8 µm, 30 inch. The final filter is a membrane with an absolute rating: 0.45 µm for clarification and bioburden reduction, as with the 0.45 µm membrane capsule, and 0.2 µm for sterile filtration. Choose the prefilter rating based on your particle load; a heavily loaded liquid may need two prefilter stages.

Within a capsule or mini-cartridge series, the size code stands for a format: a different filter area and, often, different connections. Size 0 is used for the larger capsules in a series, as with the depth-filter capsule, 8 µm, size 0, while sizes 7, 8 and 9 are the smaller formats, such as the sterile capsule, size 9. The codes are not the same across all series, so always check the filter area and the inlet and outlet connections on the product page before you order. Send us your current filter and we will find the match: sales@luminixhealth.com.

The pack size is in every product title, so check it before you compare. Large cartridges usually come as 1 piece, for example the depth-filter cartridge, 8 µm, 10 inch. Larger capsules are often packed per 2 pieces, as with the depth-filter capsule, size 0, and smaller capsules per 4 pieces, like the sterile capsule, size 9. Mini cartridges usually come in packs of 5 pieces. If you need a different quantity for a validation run or a framework agreement, ask us: sales@luminixhealth.com.

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.
