Cylindrical dropping funnel 50 ml K+H NS 24/29 with pressure equalisation, ungraduated is laboratory glassware intended for controlled, dropwise addition of liquids in synthesis, extraction and general wet-chemistry work. The cylindrical reservoir has a nominal capacity of 50 ml and is supplied ungraduated, while the integrated pressure-equalisation side arm keeps internal and external pressures balanced during transfer, avoiding vacuum lock and supporting steady flow. Cone and socket ground joints NS 24/29 allow direct connection to standard flasks and apparatus. An NS stopcock plug fitted with threaded stopcock securing delivers reliable shut-off; the bore diameter is 2,5 mm for fine regulation of reagent delivery. This funnel from manufacturer Witeg is well suited to dosing tasks in research, preparative and quality-control laboratories where pressure-compensated addition of solvents or reactive liquids is required. It is offered in a pack of 2 pieces, with a net weight of 0,106 kg. The robust glass construction supports repeated use under typical laboratory conditions for accurate liquid handling.
This article is part of Dropping funnels, in Funnels.

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.
