Cylindrical dropping funnel 25:0,5 ml K+H NS 14/23 with pressure equalisation is a graduated laboratory dosing funnel designed for controlled addition of liquids in synthesis and analytical work. The cylindrical body carries clear graduation marks at 0,5 ml intervals for accurate volume monitoring, while the integrated pressure-equalisation arm maintains balanced internal pressure during dropwise delivery. A valve stopcock fitted with a PTFE valve spindle ensures smooth, chemically resistant flow control; the bore measures 2,5 mm. Standard ground joints (cone and socket) NS 14/23 allow direct connection to common laboratory glassware. Supplied as a pack of two pieces from manufacturer Witeg, each funnel has a net weight of 0,07 kg and is intended for routine organic and inorganic preparative procedures where precise, drip-free reagent addition is required. The combination of graduated cylindrical geometry, PTFE-sealed stopcock and pressure equalisation makes this funnel a practical choice for reaction setups, titrations and solvent transfers under atmospheric or slightly elevated pressure conditions in research and quality-control laboratories.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel cylindrical 25:0,5ml C+S ST 14/23
What is this article?
Dropping funnel cylindrical 25:0,5ml C+S ST 14/23 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, in Labmateriaal.
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.
