Description
Dropping funnel, conical, provides controlled liquid addition for synthesis, extraction support and general laboratory reagent handling. This version has a 250 ml capacity, a standard ground joint NS 29/32 and a glass plug for secure on/off flow regulation. The conical geometry aids visibility of the contents and promotes complete drainage during gradual introduction of reactants into flasks or reaction vessels. Delivered as 1 pc and weighing 0,460 kg, it fits established jointed glassware systems used in research and teaching laboratories. The NS 29/32 joint ensures compatibility with matching round-bottom flasks, adapters and condensers, while the glass plug offers a simple, reusable seal. From manufacturer Lenz, the funnel is intended for routine dropping-funnel applications where medium volumes must be added in a controlled manner. Its conical profile balances working volume with manageable overall size, making it suitable for preparative chemistry and related laboratory procedures that rely on precise, observable liquid transfer.

What is this article?
Dropping funnel, conical, 250 ml, NS 29/32, glass 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.
