Description
Flat-bottom flask with standard ground joint is a large-capacity laboratory flask fabricated from borosilicate glass 3.3, delivered without a stopper and finished with a white inscription. The vessel has a volume of 4000 ml and a socket ground joint NS 29/32, and complies with DIN EN ISO 4797. Its flat bottom allows secure placement on laboratory benches, hotplates or stands, while the standardised NS joint enables straightforward coupling to condensers, distillation heads and other jointed apparatus. Borosilicate 3.3 offers the chemical durability and thermal behaviour expected for heating, mixing, concentration and bulk preparation of solutions. White markings support clear identification during multi-step procedures. Suitable for preparative chemistry, media preparation and larger-scale laboratory operations, this flask from manufacturer Hecht provides a practical wide-volume option when smaller flasks are insufficient. The open configuration without stopper suits continuous setups or user-selected closures. Pack size is 1 pc, ideal for dedicated large-volume workstations or specialised applications requiring a single high-capacity flat-bottom flask.
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.
