What is this article?
Dosing funnel for powdery substances, 250 ml, socket size 29/32, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Powder funnels, inside Funnels, in Labware.
A powder funnel has a wide bore and a short, steep cone so a solid does not bridge on the way into a bottle. A liquid funnel's narrow stem is exactly the wrong tool for a powder.
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.
