Description
Filtration apparatus designed as a closed filter holder enables reliable microbiological and analytical sampling as well as testing of gas in pressurized lines. The unit comprises a funnel-shaped base fitted with a hose nipple, a metal sintered frit serving as filter support, a sealing ring, and a matching funnel-shaped top part that also carries a hose nipple together with a back-pressure screen. Thanks to its streamlined geometry and optimised flow-path design, microorganisms and particles retained on the filter are distributed uniformly across the membrane surface. The complete holder can be autoclaved or sterilised in a hot-air oven, supporting repeated use under controlled laboratory conditions. With a net weight of 0,450 kg this compact Sartorius filtration device is easy to integrate into existing sampling setups. Ideal for gas-line monitoring and analytical workflows, it provides a robust, sterilizable solution that maintains sample integrity while ensuring even particle capture on the filter medium.

Questions about Filter holder closed
What is this article?
Filter holder closed is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Bottle-top & vacuum filtration units, inside Filtration, in Lab consumables.
A bottle-top filter or a vacuum filtration unit sits on a bottle and pulls a liquid through a membrane under vacuum. Pore size and membrane are the same choice as a syringe filter, at a larger area. A sterile unit is a stated claim. The bottle neck has to match.
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.
