Description
Cylindrical dropping funnel with PTFE stopcock, NS 19/26, 100 ml is glass laboratory equipment intended for measured addition of reagents during synthesis, work-up and analytical procedures. Fabricated from high-quality borosilicate glass LBG 3.3, it offers the chemical durability and heat resistance expected in routine wet chemistry. The cylindrical vessel allows clear reading of fill level, and the PTFE stopcock provides fine control of flow with broad reagent compatibility. A plastic stopper seals the top. Ground joint NS 19/26 matches widely used laboratory glassware, simplifying connection to flasks and receivers. This 100 ml model from manufacturer Labbox belongs to the GLASSCO line and is supplied as one piece with a net weight of 0,240 kg. It is well suited to dosing-funnel and dropping-funnel applications that need reliable, dropwise transfer of liquids in teaching labs, research groups and quality-control environments where standard jointed glassware is already in place.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel, cylindrical, with PTFE stopcock, 19/26, 100 ml
What is this article?
Dropping funnel, cylindrical, with PTFE stopcock, 19/26, 100 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.
