Description
Flat-bottom flask with standard ground joint is a laboratory vessel made from borosilicate glass 3.3, supplied without a stopper and marked with a durable white inscription. It offers a working volume of 2000 ml and a socket ground joint NS 29/32, and is produced in accordance with DIN EN ISO 4797. The flat base provides stable standing on the bench or heating surface, while the standardised joint supports reliable connection to condensers, adapters and other ground-joint glassware. Borosilicate 3.3 glass combines good chemical resistance with thermal stability suited to everyday heating, boiling, dissolution and sample preparation tasks. Clear white volume and identification markings aid quick recognition in busy laboratory workflows. This flask from manufacturer Hecht is intended for general chemistry, teaching laboratories and routine analytical work where a robust flat-bottom reaction or storage vessel is required. The design without stopper leaves the neck free for continuous setups or for pairing with separately selected closures. Pack size is 10 pc(s), making the item practical for equipping multiple workstations or replenishing glassware stocks.
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.
