Description
Round-bottom flask with standard ground joint NS 29/32 is a 50 ml laboratory flask produced from borosilicate glass LBG 3.3 and supplied in a pack of 12 pieces. The spherical design supports even heating and efficient stirring of reaction mixtures, while the standardised NS 29/32 joint connects cleanly to condensers, adapters, and other ground-joint components. Made of borosilicate glass 3.3, these flasks are suitable for organic synthesis, distillation, and receiving or collection tasks in preparative workflows. The twelve-piece pack, with a net weight of 0,865 kg, helps equip multiple workstations, parallel experiments, or teaching laboratories with consistent glassware. Classification under round-bottom flasks, ground-joint flasks, distillation flasks, and receiving flasks reflects common laboratory practice. Within the LBG range from manufacturer Labbox, this 50 ml NS 29/32 variant offers a practical multi-pack solution for facilities that need interchangeable joint glassware in borosilicate 3.3 for routine chemical handling and apparatus assembly.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Ballon à distiller fond rond, LBG 3.3, embouchure 29/32, 50 ml, 12 pièces
What is this article?
Ballon à distiller fond rond, LBG 3.3, embouchure 29/32, 50 ml, 12 pièces is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
