Description
Pear-shaped flask 50 ml with NS 24/29 ground joint is a clear Economy laboratory vessel made from borosilicate glass 3.3. The pointed base concentrates small residual volumes, supporting efficient heating, stirring and recovery during synthesis, distillation and concentration tasks. A single standard ground joint NS 24/29 provides a reliable connection for condensers, adapters and other common glassware. Manufactured by Witeg from chemically resistant borosilicate glass 3.3, the flask combines thermal-shock tolerance with compatibility toward typical laboratory solvents and aqueous media. Clear glass allows straightforward visual observation of reaction mixtures, colour development and phase behaviour throughout the experiment. Nominal capacity is 50 ml. Net weight is approximately 0,046 kg. Supplied as one piece in the Economy line, this flask is a practical choice for routine preparative work, teaching laboratories and general organic or analytical procedures where a robust pear-shaped vessel with NS 24/29 joint is required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask pear shaped 50 ml ST 24/29 Economy
What is this article?
Flask pear shaped 50 ml ST 24/29 Economy 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.
