Beschrijving
Flat-bottom flask with standard ground joint LBG 3.3, NS 19/26, 100 ml is a single laboratory flask intended for heating, stirring and general reaction work where a stable base is required. It is made from borosilicate glass 3.3, offering the thermal and chemical resistance expected of high-quality laboratory glassware for aqueous solutions and many common solvents. The nominal volume of 0,1 l suits small-scale synthesis, sample preparation and educational demonstrations. The NS 19/26 standard ground joint provides a larger, interchangeable connection compatible with matching condensers, dropping funnels and adapters, supporting leak-resistant assemblies under normal laboratory use. A flat bottom allows the vessel to stand securely on hotplates, magnetic stirrers and work surfaces. Supplied as one piece from manufacturer Labbox within the LBG range, the flask has a net weight of 0,050 kg. Transparent walls enable continuous observation of reaction progress, colour shifts and mixing behaviour. This configuration is well suited to research, teaching and quality-control environments that standardise on NS 19/26 jointed glassware and require dependable borosilicate construction for everyday experimental tasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kookkolf, vlakke bodem, LBG 3.3, hals 19/26, 100 ml
What is this article?
Kookkolf, vlakke bodem, LBG 3.3, hals 19/26, 100 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.
