Description
Cylindrical dropping funnel with PTFE stopcock, NS 14/23, 50 ml is laboratory glassware for controlled addition of liquids in synthesis, extraction and titration work. The body is made from high-quality borosilicate glass LBG 3.3, giving good chemical resistance and thermal stability for everyday organic and analytical use. Its cylindrical form makes the liquid level easy to observe, while the PTFE stopcock supports smooth, adjustable dosing and holds up well against many common reagents. A plastic stopper closes the upper opening. The NS 14/23 ground joint fits standard laboratory assemblies so the funnel can be integrated into existing setups without adapters. This 50 ml unit from manufacturer Labbox is part of the GLASSCO range and is offered as a single piece with a net weight of 0,234 kg. It suits dosing-funnel and dropping-funnel tasks wherever precise, dropwise reagent delivery is required on the bench in teaching, research or quality-control laboratories.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel, cylindrical, with PTFE stopcock, 14/23, 50 ml
What is this article?
Dropping funnel, cylindrical, with PTFE stopcock, 14/23, 50 ml is the article on this page. Luminix Health distributes Labbox 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.
