Description
Dropping funnel 500 ml NS 29/32 is a cylindrical, graduated laboratory funnel intended for controlled addition of liquids in synthesis and preparative work. The body is graduated 500 : 10 ml, enabling clear volume monitoring during dosing. It combines a ground joint core and socket NS 29/32 with an NS-PTFE stopcock plug secured by a threaded stopcock retainer, giving reliable sealing and smooth flow adjustment. The stopcock bore is 4 mm, suitable for typical laboratory reagent streams. This configuration supports dropwise or continuous addition under inert or ambient conditions when paired with matching NS glassware. Supplied from manufacturer Witeg, the funnel is a standard borosilicate-type dosing accessory for organic and inorganic preparative setups, extraction trains and reaction vessels that use NS 29/32 joints. The cylindrical graduated form aids reproducible addition rates and residual-volume estimation. Pack unit is two pieces, convenient for parallel setups or spare capacity in teaching and research laboratories requiring robust, PTFE-sealed dropping funnels.

Questions about Dropping funnels 500ml ST 29/32
What is this article?
Dropping funnels 500ml 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.
