Description
Dropping funnel 100 ml NS 19/26 is a cylindrical glass dosing funnel intended for measured addition of liquids in laboratory synthesis and preparative work. Pressure equalisation, a graduated scale (100:2 ml), drop counter, NS stopcock plug and threaded stopcock securing allow controlled, dropwise delivery while maintaining system balance. The NS 19/26 ground joint and 2,5 mm bore match common jointed glassware trains and provide a defined flow opening. Supplied in a pack of 2 pieces at 0,125 kg net weight, this funnel from manufacturer Witeg supports dropping-funnel and dosing applications that need readable volume marks and reliable stopcock retention. It is suited to organic chemistry, slow reagent introduction and general wet-lab procedures where pressure-equalised addition helps keep closed assemblies stable during continuous or intermittent feeds.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel 100ml ST 19/26
What is this article?
Dropping funnel 100ml ST 19/26 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.
