Description
Funnel bottom section with glass frit is a dedicated labware component for 25 mm vacuum filtration assemblies used in routine sample preparation and solid–liquid separation. The glass frit provides a stable, porous support surface that holds the filter medium during vacuum-assisted filtration, helping maintain alignment of the filtration path and collect filtrate cleanly into the receiving vessel. Designed specifically for 25 mm vacuum filtration units, this bottom section integrates into modular filtration setups common in analytical chemistry, microbiology sample work-up, and general laboratory clarification workflows. Supplied as a single piece weighing 0,045 kg, it is a compact replacement or spare part when the lower funnel element of a small-format vacuum filter holder needs renewal. The component is offered from manufacturer DWK Life Sciences and fits the filtration-device and filter-holder category of laboratory separation equipment. Use it wherever a fritted funnel base is required to complete or restore a 25 mm vacuum filtration train without altering the established unit geometry. Clear identification as a funnel bottom section with glass frit supports straightforward ordering for method-standardised benches and shared filtration stations.

Questions about Funnel bottom section with glass frit, for 25 mm vacuum filtration unit
What is this article?
Funnel bottom section with glass frit, for 25 mm vacuum filtration unit is the article on this page. Luminix Health distributes DWK Life Sciences 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.
