Beschreibung
Jacketed dropping funnel 250 ml with socket and cone NS 29/32 and glass stopcock 4 mm is a graduated laboratory vessel for controlled reagent addition under defined temperature conditions. Fabricated from borosilicate glass 3.3, the funnel incorporates a double-walled jacket fitted with GL 14 tempering connections, complete with cap and plastic olive 8,6 mm (PP) that allow circulation of heating or cooling media. The hollow glass stopcock NS 14,5 offers a 4 mm bore for precise flow regulation, while the design deliberately omits a pressure-equalizing tube. Graduations support accurate volume measurement during dosing, synthesis or extraction work. This dropping funnel from manufacturer Rettberg combines the chemical resistance and thermal-shock durability of borosilicate glass 3.3 with standard NS 29/32 ground joints for seamless integration into existing apparatus. Nominal volume is 0,25 l and net weight is 0,630 kg. The unit is well suited to organic synthesis, process development and analytical laboratories that require reliable liquid handling together with optional thermal control of the contents.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Dropping funnel with temp. jacket 250 ml joints size 29/32, stopcock 4 mm,
What is this article?
Dropping funnel with temp. jacket 250 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 Laborbedarf.
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.
