Description
47 mm vacuum filtration unit with ground glass joint is a complete glass assembly for laboratory vacuum filtration using 47 mm filters. The set includes a 500 ml funnel attachment, a funnel bottom section with ground joint sleeve 40/35, a vacuum connection, and a glass frit of porosity 40–60 µm as the filter support, together with an aluminium bracket and a 2000 ml flask. This configuration supports filtration by means of glass fibre filters and related media in research and analytical environments. Supplied as a single unit weighing 1,800 kg, the assembly provides an integrated path from funnel to receiving flask under vacuum. Available from manufacturer DWK Life Sciences, the unit is intended for particulate separation, sample clarification, and routine vacuum-assisted filtration workflows. The ground glass joint and 40/35 sleeve promote a secure fit between sections, while the specified frit porosity offers stable mechanical support for the filter disc during operation. Laboratories performing glass-based vacuum filtration benefit from the matched funnel, frit, bracket, and 2000 ml receiver in one ready-to-use package for consistent day-to-day filtration work.

Questions about 47 mm vacuum filtration unit, with ground glass joint, 1 unit(s)
What is this article?
47 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.
