Description
Funnel bottom section with glass frit is a glassware component for laboratory vacuum filtration assemblies. It combines a filter-support frit with a vacuum connection and a 40/35 ground joint sleeve, enabling secure coupling to matching flasks and funnel parts in standard filtration setups. This bottom section forms the interface between the filter support and the receiving vessel during vacuum-assisted separation work. Supplied as one piece and weighing 0,245 kg, it is suited to replacement of worn parts or to building modular filtration units for research and analytical laboratories. From manufacturer DWK Life Sciences, the component belongs to the filtration devices and filter holders category used in filtration, water purification, dialysis, and separation applications. The integrated vacuum connection allows controlled application of reduced pressure, while the 40/35 ground joint sleeve supports a stable glass-to-glass fit. Laboratories running glass vacuum filtration systems can use this funnel bottom section with compatible funnels, brackets, and receiving flasks to maintain reliable filtrate collection and consistent mechanical support of the filter medium throughout routine sample-preparation and particulate-separation procedures.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about Funnel bottom section with glass frit, vacuum conn., 40/35 ground joint sleeve
What is this article?
Funnel bottom section with glass frit, vacuum conn., 40/35 ground joint sleeve is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Lab consumables.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
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.
