Description
Dropping funnel with pressure equalisation 25 ml ungraduated is a cylindrical laboratory glassware item designed for controlled addition of liquids under equalised pressure. The ungraduated funnel has a capacity of 25 ml and is fitted with an NS stopcock plug secured by a threaded retainer. Both the cone and socket are NS 14/23, while the stopcock bore measures 2,5 mm, enabling precise flow regulation. Pressure equalisation ensures smooth dripping without vacuum build-up when the funnel is used on closed systems. Net weight is 0,075 kg. This dropping funnel from manufacturer Witeg is intended for preparative and analytical chemistry applications requiring reliable, grease-free stopcock performance and standard ground-joint compatibility. It is supplied in packs of two pieces for convenient laboratory stocking.

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.
