Description
Dropping funnel 100 ml NS 19/26 is a cylindrical graduated laboratory funnel designed for precise dropwise addition of liquids during chemical reactions and analytical procedures. With a working capacity of 100 ml and graduation marks every 2 ml, it enables accurate volume monitoring throughout the dosing process. The unit incorporates a standard ground joint system consisting of cone and socket NS 19/26 together with a stopcock bore of 2,5 mm. Its valve stopcock features a PTFE valve spindle secured by a threaded stopcock lock, ensuring leak-free performance and preventing unintended opening. Constructed without pressure equalisation, the funnel is ideal for gravity-driven transfers under normal atmospheric conditions. This laboratory glassware item from manufacturer Witeg is particularly useful in organic synthesis, reagent addition and general preparative chemistry where controlled flow rates are essential. Supplied in a pack of 2 pieces and weighing 0,127 kg net, the cylindrical form allows clear scale visibility while the PTFE components provide broad chemical compatibility. Researchers and technicians rely on such dropping funnels for reproducible results in both academic and industrial laboratory settings requiring reliable ground-joint connections.

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