Description
Dropping funnel 100 ml NS 14/23 is a cylindrical, graduated laboratory funnel designed for precise liquid dosing in small- to medium-scale chemical work. It incorporates a drop counter and a Preciso NS stopcock plug secured by a threaded stopcock lock, enabling controlled addition without pressure equalisation. Two NS 14/23 ground joints allow direct connection to standard glassware assemblies. The 100 ml capacity suits reagent delivery, solvent addition and stepwise synthesis steps where compact graduated dropping funnels are required. Net weight is 0,128 kg. Supplied as a pack of 2 pieces from manufacturer Witeg, this funnel supports everyday preparative and analytical routines in research, teaching and quality-control laboratories. The cylindrical body, clear graduation and drop-counter geometry facilitate reproducible flow observation, while the threaded stopcock security helps maintain reliable sealing during repeated use. Ideal for organic chemistry benches and general laboratory dosing applications that specify NS 14/23 joints and non-pressure-equalised operation.

Questions about Dropping funnel 100ml ST 14/23
What is this article?
Dropping funnel 100ml ST 14/23 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Dropping funnels, inside Funnels, in Matériel de laboratoire.
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.
