Description
Pear-shaped flask with standard ground joint is a laboratory glassware item made from borosilicate glass 3.3, carrying a white inscription and specified according to DIN 12383. The flask has a volume of 100 ml and a female ground joint NS 14/23, and it is supplied without a stopper. Its pear-shaped body is designed for laboratory use where a tapered vessel geometry is preferred. Borosilicate glass 3.3 is the material of construction for routine chemical laboratory environments. The white inscription aids visual identification of the flask during handling and storage. Offered in packs of 10 pieces, this item comes from manufacturer Hecht and fits into standard ground-joint glassware systems. The NS 14/23 socket matches common condensers, still heads and adapters used in teaching and research laboratories. Compliance with DIN 12383 supports dimensional consistency across interchangeable components. Because no stopper is included, the open neck can be fitted with user-selected closures or left free for continuous apparatus connections. Typical applications include distillation, concentration steps and small-scale reaction work that rely on pear-shaped flasks with standard joints.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

What is this article?

Un ballon à fond rond est le ballon chauffé d'une distillation ou d'un reflux. La paroi courbe reçoit la chaleur, et le col rodé se raccorde à une tête de distillation ou à un réfrigérant. La taille du rodage, et pas seulement le volume, doit correspondre au reste du montage.
Un bécher est un récipient de travail ouvert : facile à verser, peu précis comme mesure. Un erlenmeyer a un fond plat et une paroi conique, ce qui permet d'agiter un liquide sans qu'il déborde. Un ballon à fond rond sert à chauffer sous un réfrigérant : la chaleur rencontre une paroi courbe et le rodage du col se raccorde au reste de la verrerie. Le verre borosilicaté est celui qui résiste aux changements de température. Ces formes sont répertoriées sous verrerie de laboratoire ISO.
