Description
Dropping funnel with pressure compensation is a laboratory addition funnel for controlled liquid dosing under equalised pressure. This 50 ml model is fitted with a solid glass plug and sleeve/cone joints NS 14/23, enabling secure connection to matching ground-joint apparatus while the pressure-compensation path reduces vapour lock and uneven flow during addition of reagents. The funnel is supplied as 1 pc and has a weight of 0,120 kg, making it convenient for small-scale organic reactions, titrations requiring slow addition, and multi-neck flask setups on the bench. Pressure compensation supports smoother delivery when the receiving vessel is closed or under mild overpressure relative to the funnel headspace. The design belongs to standard laboratory glassware for dropping and separating operations and is manufactured by Lenz. Clear 50 ml capacity and NS 14/23 joints help laboratories keep interchangeable glassware inventories consistent across teaching, method development, and preparative chemistry. Use it wherever metered addition of solvents, catalysts, or reactive intermediates is required without interrupting the closed system.

Questions about Dropping funnel w. pressure compensation, solid glass plug, sl./co. 14/23, 50 ml
What is this article?
Dropping funnel w. pressure compensation, solid glass plug, sl./co. 14/23, 50 ml is the article on this page. Luminix Health distributes Lenz 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.
