Description
Dropping funnel with pressure equalisation 50 ml is a cylindrical, graduated laboratory funnel designed for controlled addition of liquids into reaction vessels while equalising pressure between the funnel and the receiving flask. It features an NS stopcock for precise flow regulation and a GL18 connection for secure attachment. Supplied as a single piece with a net weight of 0,078 kg and identical gross weight, the 50 ml capacity unit supports accurate dosing in organic synthesis, extractions and multi-step preparations. The pressure-equalisation design prevents vacuum lock or pressure build-up during addition, ensuring smooth operation under atmospheric or slightly reduced-pressure conditions. This funnel from manufacturer Witeg originates in Germany (Baden-Württemberg) and integrates readily into standard ground-joint glassware assemblies used in research and teaching laboratories. Its graduated cylindrical body allows visual monitoring of volume delivered, while the compact mass of 0,078 kg facilitates easy handling and mounting on stands or clamps. Suitable for routine analytical and preparative chemistry, the dropping funnel contributes to reproducible reagent introduction and process safety in distillation, reflux or titration set-ups requiring metered liquid transfer.

Questions about Dropping funnel with pressure equal., c
What is this article?
Dropping funnel with pressure equal., c is the article on this page. Luminix Health distributes Witeg 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.
