Description
Round-bottom flask 1000 ml with standard ground joint is a laboratory glassware item featuring a socket NS 29/32 and short neck. Produced from borosilicate glass 3.3 in accordance with DIN EN ISO 4797, it offers a nominal volume of 1 l and supports reliable connections in distillation and receiving applications. The round-bottom form promotes even heat distribution during heating or reaction work. Categories such as ground-joint flasks and distillation flasks highlight its versatility for standard laboratory assemblies. Packed to 10 pieces in cartons from manufacturer Marienfeld, the flask integrates readily into existing glassware trains thanks to the precise NS 29/32 joint. Borosilicate glass 3.3 delivers the chemical resistance and thermal stability required for repeated use under typical laboratory conditions. Short-neck geometry aids handling and reduces dead volume when connecting condensers or adapters. This flask meets the dimensional and material requirements of DIN EN ISO 4797, ensuring interchangeability with other compliant components for synthesis, distillation or collection tasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks 1'000 ml with round bottom and ground joint
What is this article?
Boiling flasks 1'000 ml with round bottom and ground joint is the article on this page. Luminix Health distributes Marienfeld 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.
