Description
Dropping funnel 50 ml NS 24/29 is a cylindrical, graduated laboratory funnel for controlled liquid addition in synthesis, titration and preparative chemistry. It is supplied without pressure equalisation and combines a ground cone and socket joint NS 24/29 with a 2,5 mm bore for steady dropwise flow. The stopcock uses a PTFE valve spindle with threaded stopcock lock, giving a secure seal and reliable open–close action during dosing. Clear graduations marked 50 : 1 ml support accurate volume reading throughout the working range. Pack size is 2 pc(s); net weight is 0,11 kg. This dropping funnel from manufacturer Witeg integrates readily into standard ground-joint assemblies on laboratory stands and is suited to organic reactions, reagent addition and routine liquid transfer in research and quality-control laboratories. The cylindrical body offers stable handling while the PTFE-equipped valve maintains chemical resistance at the critical sealing point. Ideal where precise, reproducible addition of liquids is required without pressure-equalising side arms.

Questions about Dropping funnels 50ml ST 24/29
What is this article?
Dropping funnels 50ml 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.
