Beschreibung
Coil condenser with cone NS 14,5/23 and socket NS 14,5/23 provides compact laboratory cooling for distillation and reflux assemblies that use smaller ground-joint glassware. The jacket length of 160 mm and the coiled internal path offer an extended cooling surface within a modest overall size, making the unit suitable for space-conscious setups. Constructed from borosilicate glass 3.3, the condenser combines chemical resistance with good thermal stability for everyday laboratory use. Matching NS 14,5/23 joints on both cone and socket ends enable direct connection to standard flasks, still heads and receivers of the same size. Delivered as one piece with a net weight of 0,142 kg, this laboratory condenser from manufacturer Rettberg is intended for general cooling duties in research, teaching and analytical environments. The product originates from Germany and carries the Rettberg® mark. Its defined dimensions, coil geometry and borosilicate construction support reliable condensation performance in routine organic and preparative workflows that rely on classic ground-joint apparatus.

Questions about Graham condenser, cone size 14,5/23, socket size 14,5/23, length 160 mm
What is this article?
Graham condenser, cone size 14,5/23, socket size 14,5/23, length 160 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.
