Description
Dropping funnel 100 ml with socket NS 29/32 and cone NS 29/32 is a graduated cylindrical laboratory funnel for controlled liquid addition in synthesis, extraction and analytical work. Made from borosilicate glass 3.3, it combines a solid glass stopcock NS 12,5 with a 2,5 mm bore, a drain tube fitted with cone NS 29/32 and a drip tip for clean delivery. Clear graduation markings support volumetric dosing of the 100 ml nominal volume, while the standardised ground joints ensure leak-tight connections to common reaction vessels and receivers. This dropping funnel from manufacturer Rettberg is intended for organic chemistry, preparative routines and quality-control laboratories where gradual reagent introduction is required. The robust borosilicate construction provides the thermal and chemical resistance expected in everyday laboratory use. Supplied as one piece, the funnel offers reliable stopcock performance and reproducible flow control for research and teaching environments that demand precise dosing of liquids under standard laboratory conditions.

Questions about Dropping funnel, 100 ml, graduated, cone/socket size 29/32,
What is this article?
Dropping funnel, 100 ml, graduated, cone/socket size 29/32, is the article on this page. Luminix Health distributes Rettberg 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.
