Description
Cylindrical dropping funnel 500 ml with pressure equalisation is ungraduated laboratory glassware for larger-scale controlled addition of liquids in synthesis and process chemistry. The cylindrical vessel features NS 19/26 core and socket joints plus an NS stopcock plug with threaded stopcock security; the 4 mm bore allows regulated flow while the pressure-equalisation path keeps internal pressure balanced during dosing into closed systems. This arrangement supports smooth reagent introduction without vapour lock or sudden pressure changes. Pack size is 2 pc(s) and each funnel has a net weight of 0,336 kg. Manufactured by Witeg, the funnel is appropriate for preparative organic work, pilot-scale reactions and routine laboratory dosing that benefits from a 500 ml ungraduated cylindrical reservoir. Ground-joint compatibility and the secured stopcock make it a practical component in standard glass apparatus requiring reliable dropwise or continuous liquid transfer.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnels cylindrical 500ml C+S ST 19/26
What is this article?
Dropping funnels cylindrical 500ml 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.
