Description
Flat-bottom flask with standard ground joint without stopper is a laboratory vessel of borosilicate glass 3.3 with white inscription, produced to DIN EN ISO 4797. The 500 ml capacity and NS 29/32 socket joint make it suitable for heating, mixing and reaction work on hotplates or stands where a stable base is required. The open neck without stopper allows free combination with matching ground-joint stoppers, condensers or adapters. Boro 3.3 glass offers the thermal-shock resistance and chemical durability expected in routine wet chemistry, distillation set-ups and teaching laboratories. White enamel markings aid quick identification of contents or working volumes during multi-step procedures. Supplied in packs of ten pieces, these flasks from manufacturer Hecht integrate readily into existing NS 29/32 glassware systems. The flat bottom provides a wide footprint that reduces tipping risk compared with round-bottom geometries, while the standardised joint ensures interchangeability across common laboratory assemblies. Ideal for synthesis, sample preparation and general preparative work that benefits from a robust, reusable borosilicate vessel.
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.
