Description
Dropping funnel with pressure compensation is a laboratory glassware item for controlled addition of liquids, fitted with a PTFE plug and a sleeve/core joint 29/32, in a 50 ml capacity. Pressure equalisation supports smooth dosing into closed or reduced-pressure systems without interrupting the addition stream, which is useful in synthesis and preparative workflows. The PTFE plug provides a chemically resistant shut-off for regulating dropwise or continuous feed of reagents into reaction vessels. With the 29/32 ground-joint interface, the funnel connects to matching flask necks and apparatus commonly used in organic and inorganic laboratory setups. This dropping funnel from manufacturer Lenz is supplied as one piece and weighs 0,120 kg, making it a compact choice for benches where small-volume additions are routine. It belongs with funnels, dropping and separating funnels used across research, teaching, and method-development laboratories. Specify this 50 ml model when pressure compensation, a PTFE plug, and sleeve/core 29/32 geometry are required for precise liquid transfer into jointed glass assemblies.
This article belongs on Dropping funnels, in Funnels.

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