Description
Dropping funnel 50 ml with socket NS 14,5/23 and cone NS 14,5/23 is a cylindrical borosilicate glass 3.3 laboratory vessel intended for controlled liquid addition in synthesis and analytical work. The body is graduated to support accurate volume monitoring, while an integrated pressure equalisation tube maintains balanced internal pressure during use. The outlet tube carries a cone NS 14,5/23 joint and drip tip, and flow is regulated by a PTFE stopcock NS 12,5 with a 2,5 mm bore that offers chemical resistance and smooth operation. This dropping funnel from manufacturer Rettberg is supplied as a single piece and integrates readily into standard ground-joint apparatus. Its 50 ml nominal capacity and compact cylindrical form make it suitable for organic chemistry, pharmaceutical research and routine dosing tasks that require precise reagent delivery. The robust borosilicate glass 3.3 construction withstands typical laboratory thermal and chemical conditions, and the drip tip promotes clean, controlled discharge into receiving vessels.

Questions about Dropping funnel, 50 ml, graduated, joints size 14,5/23, stopcock 2,5 mm,
What is this article?
Dropping funnel, 50 ml, graduated, joints size 14,5/23, stopcock 2,5 mm, is the article on this page. Luminix Health distributes Rettberg 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.
