Description
Flat-bottom flask of borosilicate glass 3.3 with standard ground joint NS 29/32, 50 ml capacity and without stopper, is a versatile vessel for heating, mixing and reaction work in the laboratory. The flat base provides stable placement on hotplates or laboratory benches, while the NS 29/32 joint allows secure connection to condensers, dropping funnels or other ground-joint apparatus. Borosilicate glass 3.3 offers excellent thermal shock resistance and chemical durability against a broad range of reagents. Supplied without a stopper, the flask can be closed with any compatible NS 29/32 stopper or adapter according to experimental needs. Available as a single unit from manufacturer Hecht, this standing flask is well suited to small-scale synthesis, distillations, extractions and general sample preparation. The 50 ml volume is ideal for micro- and semi-micro procedures commonly performed in research, teaching and quality-control laboratories. Its clear glass walls permit easy visual monitoring of contents and reaction progress. The combination of standardised joint and robust material ensures reliable performance across repeated thermal cycles and routine laboratory handling.

What is this article?
Ballons à fond plat, verre borosilicaté 3.3, avec rodage normalisé, sans is the article on this page. Luminix Health distributes Hecht 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.
