Description
90 mm vacuum filtration unit is a complete glass assembly for laboratory filtration under vacuum, designed for use with filter papers and related cellulose media. The set comprises a 1000 ml funnel attachment secured by a screw clip, a funnel bottom section fitted with a 40/35 ground joint sleeve, a vacuum connection of 6 mm diameter, and an integrated glass frit. Together these components form a stable filtration path suited to routine sample clarification and solids collection in analytical and preparative workflows. The ground glass joint ensures a reliable seal between funnel sections during operation, while the vacuum port supports connection to standard laboratory vacuum lines. Supplied as a single unit and weighing 1,75 kg, the assembly is intended for filtration setups that rely on glassware rather than disposable plastic holders. This vacuum filtration unit from manufacturer DWK Life Sciences fits categories covering vacuum technology, paper filtration, and glass filtration units, offering a reusable glass configuration for laboratories that process aqueous or solvent-based samples by vacuum-assisted filtration.

Questions about 90 mm vacuum filtration unit, with ground glass joint, 1 unit(s)
What is this article?
90 mm vacuum filtration unit, with ground glass joint, 1 unit(s) 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.
