Description
Spherical dropping funnel 250 ml ungraduated is laboratory glassware intended for controlled addition of liquids during chemical reactions and dosing procedures. The ungraduated spherical body is fitted with an NS stopcock plug incorporating threaded stopcock security to maintain secure closure during use. It provides core and sleeve joints in NS 24/29 together with a 4 mm bore for reliable flow regulation. Supplied by manufacturer Witeg in packs of 2 pieces, the funnel has a net weight of 0,158 kg and integrates readily with standard ground-joint apparatus. Typical applications include reagent addition in synthesis, sample transfer and general liquid handling where volume graduations are unnecessary. The clear spherical design permits visual monitoring of contents while the NS connections ensure leak-resistant coupling to flasks and receivers in research and analytical laboratories.

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.
