Description
Dropping funnel 1000 ml with socket NS 29/32 and cone NS 29/32 is a cylindrical laboratory dosing funnel for controlled liquid addition in synthesis and preparative work. Made of borosilicate glass 3.3, it is graduated and equipped with a pressure-equalizing tube, a solid glass stopcock NS 18,8 with 6 mm bore, and a drain tube ending in a drip tip. The 1 l nominal volume supports accurate metering of reagents into reaction vessels under equalized pressure. Ground joints NS 29/32 ensure reliable connection to standard laboratory glassware assemblies. This graduated dropping funnel from manufacturer Rettberg is intended for organic and inorganic laboratory applications requiring precise dropwise or continuous addition. The robust borosilicate construction provides good chemical and thermal resistance for everyday lab use. Net weight is 0,640 kg. Supplied as a single piece, it fits dosing and dropping-funnel workflows in research, teaching, and quality-control laboratories where cylindrical geometry, graduation, and pressure equalization are required for safe and reproducible liquid transfer.

Questions about Dropping funnel, 1000 ml, graduated, joints size 29/32, stopcock 6 mm,
What is this article?
Dropping funnel, 1000 ml, graduated, joints size 29/32, stopcock 6 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Entonnoirs à addition, inside Entonnoirs, in Matériel de laboratoire.
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.
