Description
Pear-shaped flask 100 ml with two necks, centre neck NS 14/23 and angled side neck NS 14/23, is a clear laboratory vessel manufactured from borosilicate glass 3.3. Outer diameter is 64 mm and overall height is 120 mm, offering a practical working volume for medium-scale synthesis, distillation and concentration. The pointed base focuses residual liquid for efficient heating and stirring, while the dual-neck arrangement supports concurrent reagent addition and attachment of condensers, dropping funnels or other ground-joint equipment. Made by manufacturer Witeg from chemically durable borosilicate glass 3.3, the flask provides good thermal-shock resistance and broad solvent compatibility. Nominal volume is 100 ml (0,1 l). Clear glass construction enables continuous visual control of reaction progress, colour changes and phase separations. Supplied as one piece, it suits preparative organic chemistry, sample work-up and multi-step laboratory workflows where an angled side neck improves access on the bench or in a heating bath.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 100 ml two necks CN + SN
What is this article?
Flask pear shaped 100 ml two necks CN + SN 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.
