Description
Round-bottom flask 1000 ml NS 24/29 is a clear-glass laboratory vessel with a single centre neck and standard ground joint NS 24/29. Manufactured from borosilicate glass 3.3, it delivers the chemical resistance and thermal stability needed for distillation, reflux and collection applications. With a nominal volume of 1 l, an outer diameter of 131 mm and a height of 210 mm, the flask provides ample working volume for preparative and process-scale laboratory work.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.
Supplied in packs of 10 pieces from manufacturer Witeg, this round-bottom flask is well suited to organic synthesis, solvent distillation and receiving duties. The NS 24/29 joint ensures broad compatibility with condensers, still heads and adapters commonly used in the laboratory. The single medium-neck geometry supports convenient charging, sampling and cleaning while retaining mechanical strength. Ideal as a reaction, distillation or receiving flask, this borosilicate glass 3.3 vessel supports consistent performance in everyday chemistry workflows.

Questions about Round bottom flask 1000 ml ST 24/29
What is this article?
Round bottom flask 1000 ml ST 24/29 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.
