Beschreibung
Jacketed dropping funnel of 100 ml nominal volume featuring socket and cone NS 29/32 plus a glass stopcock with 2,5 mm bore supports accurate, temperature-regulated reagent addition in laboratory synthesis. Constructed from borosilicate glass 3.3, the funnel is graduated and provided without a pressure-equalisation tube. A hollow glass stopcock NS 14,5 controls flow, while tempering connections with GL 14 thread, cap and 8,6 mm polypropylene olive permit circulation of heating or cooling fluid around the jacket. This design maintains the contents at a chosen temperature throughout dropwise delivery, enhancing selectivity and process safety. The larger NS 29/32 joints suit medium-scale apparatus common in preparative chemistry. Offered by manufacturer Rettberg, the funnel is well suited to organic reactions, extractions and other workflows that demand controlled addition under thermal management. Net weight is 0,465 kg; the item is supplied as a single piece ready for integration into standard glassware setups in research and development laboratories.
This article is part of Reaction vessels & jacketed vessels, in Beakers & flasks.

Questions about Dropping funnel with temp. jacket 100 ml joints size 29/32, stopcock 2,5 mm,
What is this article?
Dropping funnel with temp. jacket 100 ml joints size 29/32, stopcock 2,5 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.
