Description
Spherical dropping funnel 25 ml ungraduated enables controlled addition of liquids in laboratory synthesis and titration work. The body is fitted with an NS stopcock plug secured by a threaded stopcock lock, cone and socket joints NS 14/23, and a bore of 2,5 mm for precise flow regulation. Its compact spherical design suits small-scale reactions where accurate dosing without graduation marks is preferred. Supplied as a pack of two pieces from manufacturer Witeg, the funnel integrates with standard ground-joint glassware assemblies commonly used in organic and analytical chemistry. Net weight per unit is 0,059 kg. This accessory supports reproducible reagent addition in teaching labs, research benches and preparative setups that rely on NS 14/23 connections and reliable stopcock performance for safe handling of liquids.

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.
