Description
Funnel with NS stopcock 14/23 is a precision glass laboratory funnel fitted with a standard ground joint and integrated NS stopcock for controlled liquid transfer in analytical and preparative work. It features a 60° cone angle, an outer diameter of 40 mm and a stopcock bore of 2,5 mm, together with a stopcock plug and threaded stopcock retainer that secure the plug during operation. Supplied as a single piece with a net weight of 0,039 kg, the funnel is well suited to filtration, phase separation and measured addition of reagents in chemistry and life-science laboratories. The NS 14/23 joint allows direct connection to complementary ground-joint glassware, reducing the need for additional adapters. Manufactured by Witeg, this analytical funnel supports routine laboratory workflows where reliable flow control and chemical resistance of borosilicate glassware are required. Its compact dimensions make it practical for both bench-top use and integration into larger apparatus assemblies. Ideal for applications ranging from simple gravity filtration to more demanding separation tasks in research and quality-control environments.

This is the ordinary funnel, in plastic, glass or steel, used to guide a liquid or a powder into a narrower mouth. The cone angle, the stem bore and the material are the choices. It does not, by itself, filter.
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.
