Description
Fritted filter funnel, 500 ml is a laboratory filtration vessel fabricated from borosilicate glass 3.3 and fitted with an integral sintered disc of porosity 3. It is intended for vacuum-assisted solid–liquid separations, precipitate collection, washing steps and clarification work in analytical, preparative and teaching laboratories. The fritted plate acts as a reusable filter medium, reducing reliance on disposable papers for many routine applications while maintaining a stable filtration bed under suction. With a nominal working volume of 500 ml and a unit weight of 0,550 kg, the funnel integrates readily with standard suction bottles, adapters and nutsche-style filtration assemblies. Glassware of this type from manufacturer Lenz is widely used where chemical resistance and thermal stability of borosilicate 3.3 are required for aqueous and many organic media. Porosity 3 supports medium-fine particle retention typical of crystallisations, catalyst recovery and general sample work-up. Supplied as one piece, the funnel is suitable for continuous laboratory service when cleaned and handled according to good glassware practice.
This article is part of Büchner & filter funnels, in Funnels.

Questions about Fritted filter funnel, 500 ml, borosilicate glass 3.3, porosity 3, 1 unit(s)
What is this article?
Fritted filter funnel, 500 ml, borosilicate glass 3.3, porosity 3, 1 unit(s) is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Büchner & filter funnels, inside Funnels, in Matériel de laboratoire.
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.
