Description
Dropping funnel with pressure compensation is a laboratory glassware item designed for controlled addition of liquids under equalised pressure conditions. It is fitted with a PTFE plug and a sleeve/core joint 29/32, and offers a working capacity of 1000 ml, making it suitable for preparative and analytical workflows where gradual reagent dosing is required. The pressure-compensation design helps maintain smooth flow when transferring solvents or reaction mixtures between vessels without interrupting the closed system. Supplied as a single piece and weighing 0,150 kg, the funnel integrates readily into standard ground-joint assemblies used in organic synthesis, extraction and titration setups. This model from manufacturer Lenz supports routine laboratory operations that demand reliable sealing and chemical resistance at the stopcock. Typical applications include dropwise addition of reagents, phase separations under controlled conditions and general liquid handling in research and quality-control laboratories. The combination of the 29/32 joint size and PTFE plug provides a practical interface with common flasks and condensers while limiting contamination risk during repeated use.

What is this article?
Dropping funnel w. pressure compensation, PFTE-plug, sleeve/core 29/32, 1000 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.
