Description
The flat-bottom flask 100 ml NS 24/29 is a clear glass laboratory vessel intended for general chemical work, heating and reaction setups on flat surfaces. Made from borosilicate glass 3.3, it combines thermal shock resistance with broad chemical durability for everyday laboratory use. The flask has a nominal volume of 100 ml (0,1 l), an outer diameter of 64 mm and an overall height of 105 mm. Its medium neck is finished with a standard ground joint NS 24/29, enabling reliable connections to condensers, dropping funnels, adapters and other jointed glassware. The flat base ensures stable standing on hotplates, stirrers and laboratory benches without additional supports. Available as a pack of 10 pieces from manufacturer Witeg, this standing flask supports synthesis, distillation, sample preparation and routine handling tasks in research, teaching and quality-control environments. Clear glass construction permits continuous visual observation of contents, colour changes and reaction progress throughout experimental procedures.

Questions about Ballon à fond plat 100 ml ST 24/29
What is this article?
Ballon à fond plat 100 ml ST 24/29 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
