Description
Büchner funnel 90 mm Ø is a porcelain laboratory filtration funnel intended for vacuum-assisted solid–liquid separations on the bench. Its perforated plate carries holes of 1,5 mm diameter, providing a stable support for round filter paper during collection of precipitates, crystals and other solids in analytical and preparative work. The porcelain body offers mechanical robustness and chemical resistance suited to routine laboratory solvents and reagents under standard filtration conditions. Each unit is supplied as 1 pc, packed individually in a carton for protected storage and transport. This Büchner funnel from manufacturer Marienfeld integrates readily into common vacuum filtration assemblies with a matching filter flask and adapter and is equally useful for gravity filtration where a perforated plate is preferred. The 90 mm diameter gives a practical working area for medium sample volumes in research, quality-control and teaching laboratories. Typical applications include isolation of solids after synthesis or precipitation, sample clean-up and general laboratory filtration tasks that require a durable, reusable porcelain nutsche-style funnel.
This article is part of Büchner & filter funnels, in Funnels.

Questions about Buechner funnels 90 mm Ø,
What is this article?
Buechner funnels 90 mm Ø, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Büchner & filter funnels, inside Funnels, in Labware.
A Büchner funnel is a perforated porcelain or plastic plate used with a rubber cone and vacuum to pull liquid through a filter paper. A filter funnel is the glass cone that holds a folded paper under gravity. The plate diameter decides the paper size.
A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
