Description
Cylindrical dropping funnel 100:2 ml K+H NS 24/29 with pressure equalisation is a graduated laboratory glassware component intended for controlled liquid addition in synthetic and analytical work. The cylindrical body holds 100 ml and carries clear graduations at 2 ml intervals, enabling reproducible dosing of reagents. A dedicated pressure-equalisation side arm keeps internal pressure balanced while the funnel is connected to a reaction vessel, supporting smooth flow without vacuum lock. Flow is regulated by a valve stopcock fitted with a PTFE valve spindle and secured by a threaded stopcock lock, giving reliable shut-off and chemical resistance at the sealing surface. Cone and socket joints in the NS 24/29 standard allow direct integration into conventional ground-joint assemblies. The stopcock bore measures 2,5 mm. This model from manufacturer Witeg is supplied in packs of 2 pieces and has a net weight of 0,141 kg. It is suited to organic synthesis, titration set-ups and general laboratory dosing tasks that require graduated cylindrical dropping funnels with pressure equalisation.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel cylindrical 100:2ml C+S ST 24/29
What is this article?
Dropping funnel cylindrical 100:2ml C+S ST 24/29 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.
