Description
Filter base, borosilicate glass for VF7 is a borosilicate glass lower component for vacuum filtration systems built around the VF7 configuration. The glass base is intended for Witt-type filtration apparatus and supports reliable solid–liquid separation under vacuum in laboratory environments. Borosilicate material contributes chemical resistance and thermal stability during routine filtration operations.
This article is part of Filtration accessories, in Filtration.
Delivered as a single piece with a net weight of 0,2 kg, this filter base is matched to VF7 assemblies so that filter supports and collection pathways remain correctly aligned. It is listed among vacuum filtration devices and serves as a functional glass element when building or maintaining filtration trains. The part is available from manufacturer Witeg for laboratories that standardise on VF7 glassware.
In analytical and preparative workflows, a dedicated VF7 filter base simplifies spare-part logistics and helps keep Witt-style filtrierapparat units complete. Use of borosilicate glass supports clarity and durability when processing aqueous samples and many laboratory solvents, making the component a practical choice for vacuum filtration, sample preparation, and related particle-retention tasks.

Questions about Support base, borosilicate glass for VF7
What is this article?
Support base, borosilicate glass for VF7 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Filtration accessories, inside Filtration, in Lab consumables.
Filtration accessories are the holders, the gaskets, the manifolds and the flasks a membrane or a Büchner setup needs. A holder for 47 mm discs does not clamp a 25 mm disc. The gasket is what actually seals.
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.
