Description
Dropping funnel 250 ml NS 24/29 is a cylindrical graduated laboratory funnel designed for controlled addition of liquids in synthetic and analytical work. It offers a capacity of 250 ml with 5 ml graduations, ground joint cone and socket NS 24/29, and a stopcock bore of 4 mm. The NS stopcock is equipped with a threaded securing mechanism for safe, leak-resistant operation during titrations, extractions and reagent dosing. Manufactured to DIN 12567, this dropping funnel from manufacturer Witeg provides reliable volumetric control and chemical resistance suitable for routine organic and inorganic laboratory procedures. The cylindrical body allows clear observation of liquid levels and drop rate. Supplied in packs of 2 pieces, the funnel integrates readily into standard ground-joint glassware assemblies. Its precise joint size and bore support reproducible addition rates essential for reaction control, sample preparation and educational demonstrations. Net weight is approximately 0,353 kg per unit, reflecting robust borosilicate construction typical of quality laboratory glassware.

What is this article?
Dropping funnels 250ml ST 24/29 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, in Labware.
A dropping funnel adds a liquid slowly into a closed reaction through a stopcock and usually a ground joint. A pressure-equalising arm keeps the funnel from air-locking. The joint size and the volume are the specification.
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.
