Beschreibung
Round-bottom flask 500 ml NS 24/29 Economy is a clear glass laboratory flask for distillation, reaction and collection applications. It is produced from borosilicate glass 3.3, offering reliable thermal and chemical resistance for routine laboratory use. A single centre neck with standard ground joint NS 24/29 allows tight, interchangeable connection to condensers, distillation adapters and other jointed glassware. The vessel has a nominal volume of 500 ml, an outer diameter of 105 mm and a height of 170 mm, making it a convenient medium-scale format for heating and mixing work. Available in packs of 10 pieces from manufacturer Witeg, this Economy round-bottom flask can be used as a distillation flask, receiving flask or general reaction vessel. Clear glass construction permits visual observation of the contents throughout the process. The standardised NS 24/29 joint supports modular glass assemblies for organic synthesis, solvent work-up and sample concentration where a heatable round-bottom geometry is preferred.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 500 ml ST 24/29 Economy
What is this article?
Round bottom flask 500 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 Laborbedarf.
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.
