Description
Cylindrical dropping funnel 250 ml K+H NS 24/29 with pressure equalisation, ungraduated is laboratory glassware for the controlled addition of larger reagent volumes in synthesis, extraction and general wet-chemistry workflows. The cylindrical reservoir holds 250 ml and is ungraduated, while the integrated pressure-equalisation side arm equalises internal and external pressure during transfer, eliminating vacuum lock and promoting consistent flow. Cone and socket ground joints NS 24/29 enable straightforward connection to standard flasks and apparatus assemblies. An NS stopcock plug with threaded stopcock securing provides dependable shut-off; the bore diameter of 4 mm accommodates higher flow rates when faster addition is required. This funnel from manufacturer Witeg is appropriate for dosing tasks in research, preparative and quality-control laboratories needing pressure-compensated delivery of solvents or reactive liquids. It is supplied in a pack of 2 pieces with a net weight of 0,256 kg. The sturdy glass construction supports repeated laboratory use for accurate, larger-scale liquid handling.
This article is part of Dropping funnels, in Funnels.
