Description
Dropping funnel, conical, is a 500 ml laboratory vessel fitted with an NS 29/32 ground joint and a PTFE plug for controlled liquid addition. The conical body supports steady drainage and clear observation of the contents during dosing, making it suitable for preparative work where reagents must be introduced gradually into a reaction mixture. The PTFE plug provides a chemically resistant shut-off that can be adjusted for dropwise or continuous flow, helping operators regulate addition rates in synthesis, extraction, and general wet-chemistry workflows. Supplied as 1 pc and weighing 0,545 kg, this funnel integrates readily with standard NS 29/32 glassware assemblies used across teaching, research, and quality-control laboratories. The design from manufacturer Lenz focuses on reliable stopcock performance and a practical conical geometry for everyday bench use. Typical applications include organic reaction setups, solvent or reagent metering, and multi-step procedures that require precise volumetric control without interrupting the closed joint system. Compact packing as a single unit simplifies inventory handling and replacement of worn funnels in busy lab environments.
This article belongs on Dropping funnels, in Funnels.

Questions about Dropping funnel, conical, 500 ml, NS 29/32, PTFE-plug, 1 unit(s)
What is this article?
Dropping funnel, conical, 500 ml, NS 29/32, PTFE-plug, 1 unit(s) is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Dropping funnels, inside Funnels, in Matériel de laboratoire.
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.
