Description
Cylindrical dropping funnel 100 ml with pressure equalisation is ungraduated laboratory glassware for controlled, dropwise addition of liquids in synthesis and analytical work. The cylindrical body carries NS 19/26 core and socket joints together with an NS stopcock plug secured by a threaded stopcock lock, while the 2,5 mm bore supports precise flow regulation under equalised pressure. This configuration reduces vapour loss and back-pressure effects when reagents are introduced into closed reaction systems. Pack size is 2 pc(s); each funnel has a net weight of 0,142 kg. Produced by manufacturer Witeg, the funnel is intended for organic preparations, titration assemblies and general dosing tasks that require a reliable cylindrical dropping funnel with ground joints. The ungraduated design keeps the vessel simple for applications where volumetric markings are unnecessary, and the pressure-equalisation path maintains smooth operation throughout addition sequences in standard laboratory glassware setups.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnels cylindrical 100ml C+S ST 19/26
What is this article?
Dropping funnels cylindrical 100ml C+S ST 19/26 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.
