Description
Round-bottom flask with standard ground joint, without stopper, is laboratory glassware produced from borosilicate glass 3.3 and marked with a white inscription. Conforming to DIN EN ISO 4797, the flask has a nominal volume of 500 ml and a socket ground joint NS 29/32 for secure coupling to compatible glassware. The round-bottom shape promotes uniform heating and thorough mixing when the vessel is placed on a heating mantle, bath or similar laboratory heat source. Delivered without a stopper, the open joint allows free choice of stopper or adapter according to the method in use. White inscription on the body supports clear identification and handling in daily laboratory practice. Packed in units of 10 pieces from manufacturer Hecht, these flasks are suited to chemical, analytical and educational laboratories that depend on standardised ground joints. Borosilicate glass 3.3, DIN EN ISO 4797 compliance and the NS 29/32 joint together provide a dependable option for distillation, reflux and general reaction work requiring interchangeable ground-glass connections and a larger working volume.
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.
