Beschrijving
Round-bottom flask with standard ground joint NS 29/32 is a laboratory flask made from borosilicate glass LBG 3.3 with a nominal volume of 50 ml. The round bottom promotes uniform heat distribution during heating, reflux, or gentle evaporation, while the NS 29/32 ground joint ensures a reliable fit with matching condensers, still heads, and adapters. Fabricated in borosilicate glass 3.3, it is intended for everyday synthetic work, distillation trains, and use as a receiving or collection flask. Supplied as a single piece with a net weight of 0,022 kg, the vessel is straightforward to integrate into existing glassware assemblies. Typical applications align with round-bottom, ground-joint, distillation, and receiving flask categories found in research, quality-control, and teaching laboratories. The LBG product type designation identifies this item within the Labbox borosilicate range, offering a clear option when a 50 ml capacity and a larger NS 29/32 joint are required for medium-scale preparations and connected apparatus setups.
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 29/32, 50 ml
What is this article?
Kookkolf ronde bodem, LBG 3.3, mond 29/32, 50 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.
