Description
Dropping funnel 50 ml NS 29/32 is a cylindrical, graduated laboratory funnel intended for precise, controlled addition of liquids in synthetic and analytical work. It combines a ground joint core and socket of NS 29/32 with an NS-PTFE stopcock plug fitted with threaded stopcock securing, ensuring stable, leak-resistant connections in standard joint assemblies. The bore measures 2,5 mm and the scale is graduated 50 : 1 ml, allowing accurate volume delivery drop by drop. Net weight is 0,106 kg. Supplied as a pack of 2 pc(s), this dropping funnel from manufacturer Witeg is well suited to organic synthesis, pharmaceutical process development, titration setups and general dosing tasks where reliable flow control and chemical resistance of the PTFE components are required. The cylindrical body simplifies handling, cleaning and mounting on stands or within multi-neck apparatus. Its robust construction supports repeated use with a broad range of solvents and reagents while maintaining joint integrity and stopcock performance throughout laboratory workflows.

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.
