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 50 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?
Flasks, boiling, pear shape with socket, DIN 12383, Boro 3.3, printing white, is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
