Description
Dropping funnel 100 ml NS 24/29 is a cylindrical, graduated laboratory funnel designed for controlled addition of liquids in synthetic and analytical procedures. The vessel is graduated in 2 ml increments and fitted with a ground joint system consisting of both cone and socket NS 24/29, enabling direct connection to standard reaction glassware. An NS-PTFE stopcock plug with threaded securing mechanism provides reliable, grease-free sealing and precise flow regulation through a 2,5 mm bore. Net weight is 0,127 kg. This dropping funnel from manufacturer Witeg combines clear volumetric markings with a secure PTFE key, making it suitable for dropwise reagent addition, extractions, and dosing tasks under inert or ambient conditions. Supplied in packs of 2 pieces, the funnel offers a practical solution for laboratories requiring reproducible liquid transfer. The cylindrical body and integrated joints ensure mechanical stability on the bench or within assembled apparatus, while the PTFE stopcock resists common organic solvents and aqueous media encountered in everyday laboratory work.

Questions about Dropping funnels 100ml ST 29/32
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.
