Description
Dropping funnel 250 ml NS 24/29 is a cylindrical, graduated laboratory glassware component intended for controlled liquid addition in synthesis, extraction and analytical workflows. It offers a 250 ml working capacity with clear 5 ml graduation intervals, enabling accurate volume monitoring during dropwise reagent delivery. The assembly combines a ground cone and socket joint NS 24/29 with an NS-PTFE stopcock plug that incorporates threaded stopcock security and a 4 mm bore for dependable flow regulation and chemical resistance. This dropping funnel from manufacturer Witeg is well suited to organic chemistry setups, reaction quenching and multi-step procedures that require secure, leak-resistant connections to complementary glassware. The cylindrical body promotes straightforward reading of the scale while the PTFE elements withstand common laboratory solvents and reagents. Net weight is 0,343 kg. Supplied as a pack of 2 pieces, the funnel supports efficient equipping of parallel workstations in research, teaching and quality-control environments where precise dosing and robust joint geometry are essential.

Questions about Dropping funnels 250 ml ST 24/29
What is this article?
Dropping funnels 250 ml 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.
