Description
Dropping funnel 50 ml with NS 19/26 ground joints is a cylindrical, graduated laboratory funnel designed for controlled addition of liquids in synthetic and analytical procedures. It features a valve stopcock fitted with a PTFE valve spindle and threaded stopcock security, providing precise flow regulation and leak-free operation. Graduation is 50 : 1 ml, enabling accurate volume monitoring during dosing. The bore diameter of the stopcock is 2,5 mm. Without pressure equalisation, the funnel is intended for standard atmospheric additions. Cone and socket joints NS 19/26 ensure compatibility with common glassware assemblies. Net weight is 0,087 kg. This dropping funnel supports a wide range of organic synthesis, titration and reagent-addition workflows where reliable metering and chemical resistance are required. Available in a pack of 2 pieces from manufacturer Witeg, it offers a practical solution for routine laboratory dosing tasks.

Questions about Dropping funnels 50ml ST 19/26
What is this article?
Dropping funnels 50ml 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.
