Description
Dropping funnel with pressure compensation is a glass laboratory funnel for regulated liquid addition with equalised headspace pressure. This 100 ml version features a solid glass plug and sleeve/cone joints NS 14/23, so it couples directly to standard-taper flasks and adapters while the compensation arm helps maintain steady flow when dosing into closed or partially closed reaction systems. Packaged as 1 pc with a weight of 0,140 kg, the funnel suits medium-scale synthetic steps, controlled quenching, and gradual introduction of reagents in organic and inorganic preparative work. Pressure compensation is particularly useful when vapour pressure or temperature changes could otherwise interrupt addition through a conventional dropping funnel. The item is produced by manufacturer Lenz and falls within laboratory glass components for dropping funnels. Defined 100 ml volume and NS 14/23 geometry support reproducible apparatus layouts, teaching demonstrations, and routine replacement of matching funnels in shared glassware pools. Ideal for research and quality-control laboratories that rely on ground-joint dropping funnels for safe, metered liquid transfer.
This article is part of Dropping funnels, in Funnels.

Questions about Dropping funnel w. pressure compensation, solid glass plug, sl./co. 14/23
What is this article?
Dropping funnel w. pressure compensation, solid glass plug, sl./co. 14/23 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.
