Description
Dropping funnel, conical, provides a 2000 ml capacity together with an NS 29/32 ground joint and a PTFE plug for high-volume yet controlled liquid addition. The conical shape aids complete drainage and clear level reading when larger reagent charges must be introduced into reactors, flasks, or receiving vessels. The PTFE plug allows operators to set dropwise or continuous flow, supporting reproducible addition rates in scale-up chemistry, pilot preparations, and multi-litre work-ups. At 1 pc per pack and a weight of 0,728 kg, the funnel remains manageable for standard laboratory handling while matching common NS 29/32 glassware trains. This configuration from manufacturer Lenz is aimed at laboratories that need greater reservoir volume without leaving the familiar joint and stopcock format. Typical uses include preparative organic synthesis, bulk solvent or reagent metering, and process steps where gradual addition protects reaction control. The single-unit presentation simplifies stocking spare funnels alongside other dropping and separating glassware on the bench or in central stores.
This article is part of Dropping funnels, in Funnels.

What is this article?
Dropping funnel, conical, 2000 ml, NS 29/32, PTFE-plug, 1 pc 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.
