Description
Dropping funnel 500 ml K+H NS 29/32 is a cylindrical, graduated laboratory funnel designed for controlled dropwise addition of reagents in synthetic chemistry, extractions and dosing operations. It offers a 500 ml capacity with graduation marks at 10 ml intervals, enabling clear volume monitoring throughout the transfer process. The integrated valve stopcock incorporates a PTFE valve spindle that delivers smooth actuation, chemical resistance and a reliable leak-tight seal. Attachment to other laboratory glassware is achieved via a ground joint consisting of cone and socket in NS 29/32 size, complemented by a 4 mm bore that permits adequate flow of typical solvents and solutions. This dropping funnel from manufacturer Witeg suits organic synthesis, preparative work and general dosing applications where accurate liquid addition and standard joint compatibility are required. The product is supplied in packs of 2 pieces and each funnel has a net weight of 0,396 kg. Its cylindrical form and PTFE components provide a practical solution for everyday use in research and quality-control laboratories equipped with NS 29/32 apparatus.

What is this article?
Dropping funnels 500ml C+S ST 29/32 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.
