Description
Powder funnel Ø 70 mm DURAN is a laboratory glass funnel for transferring powders and granular solids into flasks, bottles and other vessels. It is manufactured from DURAN® tubing in borosilicate glass 3.3, combining recognised glass quality with chemical resistance and thermal stability for daily laboratory use. The funnel has a diameter of 70 mm and a short, wide stem that encourages free flow of dry materials and reduces the risk of bridging during solid addition. Offered as a single piece, this powder funnel from manufacturer Witeg is well suited to analytical chemistry, sample preparation and general preparative work where dependable glass funnels are needed. The short wide stem design supports efficient charging of reaction vessels and storage containers while maintaining stable seating on vessel necks. With a net weight of 0,037 kg it remains easy to handle yet robust enough for repeated cleaning and routine use. As an analytical funnel option within standard glass funnel categories, it provides a clear, practical solution for powder handling in research, quality-control and teaching environments without added complexity.

Questions about Powder funnels, made from DURAN tubing
What is this article?
Powder funnels, made from DURAN tubing is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Powder funnels, inside Funnels, in Matériel de laboratoire.
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.
