Description
Claisen pear-shaped flask 100 ml MH + SH NS 14/23 is a two-neck laboratory flask with a pointed, pear-shaped body designed for distillation, fractionation and synthetic operations at the 100 ml scale. Nominal volume is 100 ml (0,1 l). Both the main neck (MH) and the side neck (SH) are equipped with standard ground joints NS 14/23, so condensers, dropping funnels, thermometers and other ground-joint accessories connect directly. The Claisen configuration of two necks enables simultaneous addition of reagents and take-off of vapour or establishment of reflux, which is the defining practical advantage of this flask geometry. The pear-shaped profile keeps the liquid volume concentrated at the base for effective heat transfer and recovery. Supplied as a single unit from manufacturer Witeg, the flask has a net weight of 0,074 kg and integrates readily into existing NS 14/23 assemblies. It serves research, process development and teaching laboratories that need robust multi-neck glassware with standardised joints for work around 100 ml.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, pear shaped, Claisen, 100 ml, C
What is this article?
Flasks, pear shaped, Claisen, 100 ml, C is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
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.
