Beschrijving
Round-bottom flask with standard ground joint, LBG 3.3, NS 19/26, 50 ml is laboratory glassware intended for distillation, reflux, reaction and collection work. It is made from borosilicate glass 3.3, giving the thermal shock resistance and chemical durability required in everyday organic and analytical chemistry. The flask has a nominal volume of 50 ml (0,05 l) and a standard ground joint NS 19/26 for reliable connection to condensers, adapters and other jointed apparatus. Net weight is 0,022 kg for the single-piece unit, making it practical for bench-scale setups. This round-bottom flask from manufacturer Labbox belongs to the LBG line and is suited to heating under reflux, solvent recovery and sample collection. Typical use categories include round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks. The spherical body supports even heat distribution and efficient mixing when used with a heating mantle or oil bath, and the joint geometry integrates cleanly into existing laboratory glassware assemblies for synthesis and purification workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flask round bottom, LBG 3.3, mouth 19/26, 50 ml
What is this article?
Boiling flask round bottom, LBG 3.3, mouth 19/26, 50 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, 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.
