Description
Flat-bottom flask with standard ground joint NS 29/32, without stopper, is a laboratory standing flask fabricated from Boro 3.3 glass with white inscription in accordance with DIN EN ISO 4797. Offering a nominal volume of 100 ml, it provides a flat base for stable positioning on the bench and a female ground joint NS 29/32 for leak-resistant coupling to standard laboratory apparatus. The flask is delivered without a stopper, allowing selection of a suitable closure or adapter for the intended process. White inscription improves visibility for labelling and everyday identification in busy laboratory settings. Manufactured by Hecht, this vessel fits established Normschliff systems used in research, analytical, educational, and production-support laboratories that depend on interchangeable ground-joint glassware. Boro 3.3 material is appropriate for routine heating, reaction, and holding applications associated with this glass class. The combination of flat-bottom geometry and defined NS 29/32 joint supports modular assembly with condensers, dropping funnels, and other matching components. Supplied in packs of 10 pc(s), the flask is convenient for stocking multiple benches or maintaining spare glassware inventories where DIN EN ISO 4797 flat-bottom flasks are standard equipment.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks, boiling, flat bottom with socket, Boro 3.3, DIN EN ISO 4797, printing
What is this article?
Flasks, boiling, flat 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.
