Description
Powder funnels in borosilicate glass 3.3 are laboratory glassware items intended for transferring powders and granular solids into flasks, bottles and other vessels. Each funnel has an outer rim diameter of 80 mm and a stem length of 25 mm, giving a wide mouth suited to dry materials while the stem supports controlled delivery into receiving containers. Borosilicate glass 3.3 provides chemical resistance and thermal stability for routine sample preparation, reagent handling and teaching use. Compared with narrow liquid funnels, the powder geometry reduces bridging and spillage when charging solids. Offered as a pack of 10 pieces from manufacturer ROTH SELECTION, the set suits multi-user benches and shared glassware stores. The pack weighs 0,570 kg and fits standard laboratory glass collections used in chemistry, life sciences and materials work. Clear glass construction allows visual monitoring during transfer. These reusable powder funnels support everyday solids handling where durable, dimensionally defined labware is required without additional performance claims beyond the stated material and sizes.
This article is part of Powder funnels, in Funnels.

Questions about Powder funnels, borosilicate glass 3.3, rim-Ø outer 80 mm, L stem 25 mm
What is this article?
Powder funnels, borosilicate glass 3.3, rim-Ø outer 80 mm, L stem 25 mm is the article on this page. Luminix Health distributes Carl Roth 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.
