Description
Cylindrical dropping funnel 100:2 ml K+H NS 29/32 with pressure equalisation is a graduated laboratory dosing funnel for controlled liquid addition in synthesis, titration and analytical work. The cylindrical body carries clear graduation marks at 2 ml intervals up to a working capacity of 100 ml, allowing continuous volume monitoring during dropwise or continuous feed. Ground joints are provided as cone and socket NS 29/32 for direct connection to standard laboratory glassware. Flow is regulated by an NS PTFE stopcock plug fitted with a threaded stopcock lock, giving chemically resistant shut-off and secure seating under routine laboratory conditions. The bore diameter of 2,5 mm supports smooth transfer of aqueous and organic media, while the integrated pressure-equalisation path keeps internal pressure balanced when the funnel is closed to the atmosphere. Offered as a pack of 2 pieces with a net weight of 0,151 kg, this dropping funnel from manufacturer Witeg is intended for reaction feeding, solvent addition and precise dosing tasks in research, teaching and quality-control laboratories that rely on NS 29/32 assemblies.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel cylindrical 100:2ml C+S ST 29/32
What is this article?
Dropping funnel cylindrical 100:2ml 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.
