Beschrijving
Distilling head 90° is a laboratory distillation attachment configured as a bend (Krümmer) for connecting a flask to a condenser in standard ground-joint assemblies. It provides a flask joint NS 29/32 and a condenser joint NS 29/32, enabling a right-angle vapour path typical of many bench-scale distillation set-ups. The component is intended for use where a compact 90° transition between boiling flask and cooler is required. Supplied as a single piece with a net weight of 0,054 kg, it integrates directly into NS 29/32 glassware trains without additional adapters when matching joints are used. This distilling head from manufacturer Witeg supports routine organic and preparative work involving reflux or simple distillation layouts that rely on standardised conical joints. Clear joint designation on both ends simplifies selection and replacement within existing apparatus. The 90° geometry keeps the condenser orientation convenient relative to the flask, aiding stable assembly on stands and clamps. Suitable for laboratories equipping or maintaining distillation lines based on NS 29/32 connections, the unit is offered as one piece for straightforward stocking and exchange.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about BENDS, 90°, FLASK-CONE ST 29/32, CONDEN
What is this article?
BENDS, 90°, FLASK-CONE ST 29/32, CONDEN is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, 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.
