Dropping funnel, 25 ml is a graduated cylindrical laboratory funnel for controlled addition of liquids at small to medium scale. It is equipped with a socket NS 14,5/23 and a drain tube ending in cone NS 14,5/23 with drip tip, ensuring compatibility with standard ground-joint apparatus. A PTFE stopcock NS 12,5 with 2,5 mm bore provides chemically resistant, smooth flow regulation. Fabricated from borosilicate glass 3.3, the funnel from manufacturer Rettberg delivers the durability and inertness needed for everyday synthesis and dosing work. Graduation on the cylindrical body allows visual volume control during reagent introduction. Nominal volume is 0,025 l and net weight is 0,067 kg. The compact format suits dosing-funnel applications, micro- to semi-micro preparations, and setups that require NS 14,5/23 joints together with a PTFE stopcock and clean drip-tip transfer. Practical for reaction trains, extractions and general liquid handling in the laboratory.

Questions about Dropping funnel, 25 ml, graduated, cone/socket size 14,5/23,
What is this article?
Dropping funnel, 25 ml, graduated, cone/socket size 14,5/23, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Druppeltrechters, inside Trechters, in Labmateriaal.
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.
