Round-bottom flask with standard ground joint NS 14/23, 10 ml, LBG 3.3 is a compact borosilicate vessel for small-scale heating, reaction and distillation work. The spherical body aids uniform heat distribution and efficient mixing of limited sample volumes, while the integral NS 14/23 ground joint enables leak-resistant connection to condensers, adapters and other standard joint glassware. Produced from borosilicate glass 3.3, the flask offers the chemical durability and thermal-shock resistance expected in routine laboratory practice. This single-piece unit from manufacturer Labbox has a nominal volume of 10 ml (0,01 l) and a net weight of 0,016 kg, making it well suited to microscale organic synthesis, method development and teaching experiments where reagent economy matters. Applications include small-volume reflux, solvent exchange, sample concentration and use as a receiving or intermediate flask in compact jointed assemblies. LBG 3.3 glass withstands common laboratory solvents and temperature changes associated with heating mantles, oil baths or water baths. The defined NS 14/23 joint size ensures interchangeability within standard European ground-joint systems used across analytical and preparative workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kookkolf ronde bodem, LBG 3.3, mond 14/23, 10 ml
What is this article?
Kookkolf ronde bodem, LBG 3.3, mond 14/23, 10 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
