Description
Dropping funnel 100 ml 1 x NS 29/32 1 x NS 14/23 is a graduated laboratory funnel designed for controlled liquid addition via mixed ground-joint connections. Mounted on an intermediate piece, it combines an NS 29/32 joint on the intermediate section with an NS 14/23 joint on the funnel itself and incorporates a stopcock plug of 3 x NS configuration. The 100 ml graduated capacity enables precise volume tracking during reagent dosing, extraction, or synthesis procedures. Net weight is 0,172 kg. This arrangement allows direct coupling to larger NS 29/32 apparatus while retaining the smaller NS 14/23 interface for the dropping section. Offered by manufacturer Witeg in packs of 2 pc(s), the funnel suits research and routine laboratory environments that employ mixed joint sizes. Graduated markings support accurate monitoring of liquid delivery, and the robust intermediate-piece layout integrates smoothly into multi-neck flasks or distillation assemblies. It provides a practical solution for dropwise addition tasks requiring both volume control and versatile ground-joint compatibility across standard glassware systems.

What is this article?
Dropping funnel 100ml 1 x ST 29/32 1 x 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.
