Description
Dropping funnel 100 ml NS 29/32 is a cylindrical, graduated laboratory funnel designed for accurate, controlled liquid addition in chemical synthesis and analytical procedures. Equipped with a ground joint core and socket of NS 29/32 together with an NS-PTFE stopcock plug and threaded stopcock securing, it provides secure, leak-resistant performance in standard joint systems. The bore diameter is 2,5 mm and the scale is graduated 100 : 2 ml for reliable volume measurement. Net weight is 0,135 kg. Offered as a pack of 2 pc(s), this dropping funnel from manufacturer Witeg supports dropwise dosing in organic chemistry, pharmaceutical research, process development and routine laboratory work where chemical resistance of the PTFE components and consistent flow control are essential. The cylindrical form facilitates easy mounting, handling and cleaning within multi-neck flasks or freestanding assemblies. Its durable construction maintains joint integrity and stopcock function across repeated use with diverse solvents and reagents in everyday laboratory environments.

What is this article?
Dropping funnels 100ml 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.
