Description
Dropping funnel 25 ml NS 14/23 is a cylindrical, graduated laboratory funnel for controlled dropwise addition of liquids in synthetic chemistry, titrations and analytical workflows. It provides a 25 ml working volume with 0,5 ml graduation intervals for clear volume monitoring during reagent transfer. The unit combines a ground joint core and socket NS 14/23 with a 2,5 mm bore that supports steady liquid flow. An NS-PTFE stopcock plug secured by a threaded stopcock lock delivers reliable sealing and safe handling under routine laboratory conditions. This dropping funnel from manufacturer Witeg suits applications that require reproducible dosing of solvents or reagents on the bench. The compact cylindrical body improves meniscus visibility and simplifies cleaning between runs. Each funnel has a net weight of 0,078 kg and is supplied in packs of 2 pieces, offering a practical format for teaching labs, R&D stations and quality-control environments that standardise on ground-joint glassware for precise volumetric control.

Questions about Dropping funnels 25ml ST 14/23
What is this article?
Dropping funnels 25ml ST 14/23 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.
