Description
Jacketed dropping funnel 500 ml with socket and cone NS 29/32 and glass stopcock 4 mm provides a graduated vessel for precise addition of liquids while maintaining temperature control. Constructed from borosilicate glass 3.3, it features a double-walled jacket equipped with GL 14 tempering connections, cap and plastic olive 8,6 mm (PP) for circulating thermostatic media. The hollow glass stopcock NS 14,5 delivers a 4 mm bore that ensures dependable flow adjustment, and the funnel is supplied without a pressure-equalizing tube. Clear graduations facilitate accurate dosing in synthetic, extraction or preparative workflows. This robust dropping funnel from manufacturer Rettberg offers the chemical inertness and thermal stability characteristic of borosilicate glass 3.3 and mates directly with standard NS 29/32 ground-joint assemblies. Nominal volume is 0,5 l and net weight is 0,800 kg. The design is intended for research, development and quality-control laboratories that need reliable reagent delivery combined with optional heating or cooling of the funnel contents.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Dropping funnel with temp. jacket 500 ml joints size 29/32, stopcock 4 mm,
What is this article?
Dropping funnel with temp. jacket 500 ml joints size 29/32, stopcock 4 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Reaction vessels & jacketed vessels, inside Beakers & flasks, in Labware.
A reaction vessel is the flask a synthesis actually runs in, sometimes jacketed so a fluid can heat or cool the wall. The joints, the working volume and the jacket connections are the specification. It is not a storage bottle.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
