Description
Dropping funnel 500 ml NS 24/29 is a cylindrical, graduated laboratory funnel intended for controlled liquid addition in synthesis, titration and dosing work. It offers a working capacity of 500 ml with clear 10 ml graduation intervals, allowing accurate volume monitoring during reagent transfer. The assembly comprises a ground-glass cone and socket joint of NS 24/29 size together with a valve stopcock fitted with a PTFE valve spindle and threaded stopcock lock; the bore measures 4 mm for steady, adjustable flow. Designed without pressure equalisation, the funnel relies on gravity feed and is therefore suited to straightforward dropping applications under ambient conditions. Supplied by manufacturer Witeg, the item is packed as 2 pc(s) and has a net weight of 0,501 kg. Its cylindrical body simplifies handling, cleaning and integration into standard NS 24/29 glassware trains commonly found in organic, analytical and preparative laboratories. The combination of graduated scale, secure PTFE-sealed stopcock and standardised joint makes this dropping funnel a practical choice for reproducible liquid dosing in research and quality-control environments.

Questions about Dropping funnels 500ml ST 24/29
What is this article?
Dropping funnels 500ml ST 24/29 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.
