Description
Claisen-Vigreux pear-shaped flask 100 ml is a laboratory glass flask with a pear-shaped body and a nominal volume of 100 ml (0,1 l). It is fitted with two necks, each finished with an NS 14/23 ground joint—one main neck (MH) and one side neck (SH)—so that condensers, adapters or other jointed components can be mounted together in a single assembly. The dual-neck layout is characteristic of Claisen-type distillation glassware and supports compact set-ups in organic and preparative work. This flask from manufacturer Witeg is supplied as a single piece and has a net weight of 0,122 kg. Joint size NS 14/23 ensures interchangeability with standard laboratory ground-joint apparatus. With its 100 ml working capacity, the vessel is practical for small-scale distillations and related procedures where a pointed or pear-shaped reservoir is preferred. The design follows the Claisen-Vigreux pattern, combining a branched neck arrangement with the pear-shaped body. It integrates readily into multi-piece glassware trains used in research and teaching laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, pear shaped, Claisen-Vigreux, 1
What is this article?
Flasks, pear shaped, Claisen-Vigreux, 1 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.
