Beschreibung
Powder funnel Ø 70 mm BORO is a laboratory glass funnel designed for the controlled transfer of powders, crystals and other dry solids into flasks, bottles and reaction vessels. Fabricated from borosilicate glass 3.3, it delivers the chemical resistance and thermal stability required for everyday analytical and preparative laboratory work. The geometry features a 60° angle, an outer diameter of 70 mm and a short, wide stem that supports free flow of granular materials and helps minimise bridging during charging. Supplied as one piece, this powder funnel from manufacturer Witeg fits sample preparation, solid addition and general laboratory handling where reliable glassware is essential. The short wide stem facilitates rapid filling of narrow-neck vessels while seating securely in use. At a net weight of 0,03 kg the funnel is lightweight yet suitable for repeated cleaning and routine handling typical of analytical funnels and glass funnel applications. Its straightforward borosilicate glass 3.3 construction makes it a practical choice for powder transfer tasks in research, quality control and teaching laboratories.

Questions about Powder funnels, with short and wide st
What is this article?
Powder funnels, with short and wide st is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Powder funnels, inside Funnels, in Laborbedarf.
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.
