Beschrijving
Claisen distilling head NS 14/23 is a laboratory glassware component for distillation assemblies that need an additional side connection. It is fitted with two sockets NS 14/23, a flask joint NS 19/26 and a condenser joint NS 19/26, so a thermometer, addition funnel or similar accessory can be mounted while vapour travels to the condenser. The Claisen geometry is widely applied in organic synthesis for vacuum distillation, fractional work-up and controlled reagent addition under reduced pressure. Supplied as one piece with a net weight of 0,069 kg, the head couples directly to matching ground-joint flasks and condensers. This configuration from manufacturer Witeg keeps dead volume modest and supports stable vapour flow in routine purification and solvent-recovery setups. Teaching and research laboratories use such heads for sample preparation, solvent distillation and reaction mixture work-up. Standardised NS joints ensure interchangeability with common European glassware systems and simplify integration into existing distillation trains without adapters.
This article belongs on Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Claisen heads, with 2 sockets ST 14/23,
What is this article?
Claisen heads, with 2 sockets ST 14/23, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labmateriaal.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
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.
