Description
Cylindrical dropping funnel 100 ml with pressure equalisation is an ungraduated laboratory glassware component for controlled liquid addition in synthesis and analytical work. It combines a cylindrical body with cone and socket NS 29/32 (K+H) and an NS stopcock plug secured by a threaded stopcock lock, allowing dropwise dosing while pressure remains equalised between funnel and receiving vessel. The 2,5 mm bore supports steady, manageable flow for reagent transfer. Capacity is 100 ml with a net weight of 0,156 kg, making the item suitable for standard ground-joint assemblies in research, teaching and quality-control laboratories. This funnel from manufacturer Witeg belongs to the categories of dropping funnels with ground joints and dosing funnels. The ungraduated cylindrical form emphasises mechanical robustness for repeated use where volumetric scale markings are unnecessary. Pressure equalisation helps avoid vapour lock or pressure build-up when adding liquids to closed reaction systems, supporting safer handling of solvents and reagents in organic and inorganic chemistry workflows.

Questions about Dropping funnels cylindrical 100ml C+S ST 29/32
What is this article?
Dropping funnels cylindrical 100ml C+S ST 29/32 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, in Labware.
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.
