Description
Round-bottom flask with standard ground joint is a compact laboratory flask made of borosilicate glass 3.3, supplied without a stopper and carrying a white inscription. It has a volume of 50 ml and a socket ground joint NS 14/23, and is manufactured to DIN EN ISO 4797. The spherical body promotes uniform heat distribution when used with heating mantles, oil baths or water baths, making the flask well suited to reflux, distillation, synthesis and small-scale reaction work. The NS 14/23 joint ensures compatibility with matching condensers, dropping funnels and adapters in standard ground-joint assemblies. Borosilicate 3.3 glass provides chemical resistance and thermal performance appropriate for routine organic and inorganic laboratory procedures. White inscription markings help identify the vessel quickly among other glassware. This flask from manufacturer Hecht is a practical choice for teaching labs, method development and preparative steps at modest volumes. The design without stopper leaves the neck free for continuous apparatus or separately chosen stoppers. Pack size is 10 pc(s), convenient for stocking multiple fume-hood stations or student benches.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, boiling, round bottom with socket, Boro 3.3, DIN EN ISO 4797, printing
What is this article?
Flasks, boiling, round bottom with socket, Boro 3.3, DIN EN ISO 4797, printing is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
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.
