Description
Diagonal condenser with stopcock socket NS 19/38 and spherical joint ball KS 35/20 is an uncoated laboratory cooler intended for Heidolph rotary evaporators. Manufactured from borosilicate glass 3.3, it delivers reliable vapour condensation during solvent evaporation and distillation work. The NS 19/38 stopcock socket together with the KS 35/20 spherical joint ball provides standardised, leak-resistant connections that integrate directly into compatible evaporator assemblies. Supplied as a single piece with a net weight of 0,917 kg, the condenser supports routine concentration, recovery and purification tasks in research and analytical laboratories. This glassware item from manufacturer Rettberg carries the Rettberg ® trademark and is purpose-built for Heidolph rotary evaporator systems. The uncoated surface preserves the chemical resistance and optical clarity characteristic of borosilicate glass 3.3, making the diagonal design suitable for continuous laboratory use where efficient cooling and straightforward joint compatibility are required.

Questions about Diagonal condenser, stopcock socket size 19/38, spherical joint ball
What is this article?
Diagonal condenser, stopcock socket size 19/38, spherical joint ball is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Stopcocks & valves, inside Tubing, hoses & fittings, in Labware.
A stopcock opens and closes a line, or directs it between ports. Glass stopcocks have a ground plug that needs grease or a PTFE key. The bore decides the flow. A two-way and a three-way key are different parts.
Tubing is how a liquid or a gas moves between two vessels without being poured. Silicone stays flexible and survives repeated autoclaving. PTFE resists almost every solvent and is stiff. PVC is the ordinary flexible line for water and for mild aqueous work. The fitting, not the tube, is what usually leaks: the barb, the thread and the stopcock have to match the tube bore. Glass and plastic apparatus around these lines is indexed under ISO laboratory ware.
