Description
Claisen-Vigreux pear-shaped flask 50 ml is a dual-neck laboratory flask for medium-micro scale distillation and synthetic applications. It provides a nominal volume of 0,05 l and features NS 14/23 ground joints on both the main neck and the side neck. The Claisen-Vigreux design incorporates an angled side arm with Vigreux indentations, favouring vapour-liquid interaction during distillation while retaining the compact pear-shaped body. Two necks permit simultaneous connection of condensers, dropping funnels or probes. Net weight is 0,074 kg and the item is supplied as a single piece. This flask from manufacturer Witeg originates in Germany and matches standard NS 14/23 laboratory joint systems. The pear geometry aids drainage of residual liquid, and the identical joint sizes on main and side necks simplify assembly of multi-component glassware trains. Suitable for organic preparative work, fractional distillation setups and general laboratory procedures that require a Claisen-Vigreux pear-shaped vessel of 50 ml capacity.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, pear shaped, Claisen-Vigreux, 5
What is this article?
Flasks, pear shaped, Claisen-Vigreux, 5 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.
