Description
Round-bottom flask with standard ground joint, without stopper, is laboratory glassware produced from borosilicate glass 3.3 with white inscription in accordance with DIN EN ISO 4797. The 1000 ml flask is fitted with a socket joint NS 24/29, enabling secure coupling to condensers, adapters, and other ground-joint apparatus commonly used in organic and analytical chemistry. Its rounded body supports even heating during reflux, distillation, and reaction procedures, while the absence of a stopper allows free selection of closures or downstream connections. White inscription keeps volume and joint size clearly legible during daily laboratory handling. Supplied in packs of 10 pieces from manufacturer Hecht, these flasks are intended for teaching labs, research facilities, and industrial quality-control settings that rely on interchangeable borosilicate glassware. Compliance with DIN EN ISO 4797 underpins dimensional interchangeability, so the NS 24/29 joint integrates smoothly into existing ground-joint systems for sample preparation, synthesis, and multi-step work-ups requiring a single standard socket.
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.
