Description
Dropping funnel with pressure compensation is a laboratory glass funnel intended for controlled addition of liquids under pressure-equalised conditions. This 250 ml model is equipped with a solid glass plug and sleeve/cone joints NS 29/32, providing a larger ground-joint interface for multi-neck flasks and scale-up assemblies while the compensation path promotes continuous, even dosing. Supplied as 1 pc and weighing 0,230 kg, the funnel addresses preparative workflows that need greater working volume than small NS 14/23 funnels, including solvent addition, reagent feeds, and staged quenching in organic synthesis. Pressure compensation helps avoid interrupted flow when the receiving vessel is sealed or when vapour generation alters internal pressure. The component comes from manufacturer Lenz and is categorised among dropping funnels within laboratory glassware. The combination of 250 ml capacity and NS 29/32 joints simplifies matching to larger reaction flasks and standard distillation or reflux trains. Suitable for research groups, pilot-support labs, and teaching environments that standardise on solid-glass-plug dropping funnels with pressure equalisation.

Questions about Dropping funnels with pressure compensation with solid glass plugs, 250 ml
What is this article?
Dropping funnels with pressure compensation with solid glass plugs, 250 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.
