Description
DURAN® dropping funnel, cylindrical, with graduation and ground joint NS 14/23 is intended for the dosed addition of solutions, reaction mixtures and chemicals in laboratory setups. The 100 ml nominal-volume unit is manufactured from borosilicate glass 3.3 and has a cylindrical body carrying an easy-to-read scale with line graduation for content measurement. Permanently fired white printing keeps the scale legible over extended use. A further standard ground joint at the lower end allows a secure, matching connection to multi-neck flasks and similar glassware. An NS stopcock with stopcock retainer enables adjustable feed rates, while the ground joint ensures a dense closure. Applications centre on steady, metered liquid delivery into reaction mixtures and on measuring liquid quantities. This single-piece funnel from manufacturer Duran/DWK Life Sciences integrates dosing functionality with volumetric convenience for everyday synthetic and analytical procedures. The graduated cylindrical geometry supports controlled addition without requiring separate measuring equipment.
This article is part of Dropping funnels, in Funnels.

Questions about DURAN® Dropping Funnel, cylindrical, with scale, and ground joint
What is this article?
DURAN® Dropping Funnel, cylindrical, with scale, and ground joint is the article on this page. Luminix Health distributes DWK Life Sciences 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.
