Beschrijving
Pointed flask with standard ground joint is a compact borosilicate laboratory flask for small-scale reactions, concentrations and sample handling. Manufactured from Boro 3.3 with white inscription and conforming to DIN 12383, it has a nominal volume of 10 ml and a female ground joint NS 14/23 for compatibility with matching stoppers, condensers and adapters. The pointed body geometry aids complete drainage and efficient recovery of limited sample volumes, which is useful in analytical workups and micro-scale synthesis. Supplied without stopper, the vessel can be closed or connected as required by the chosen joint accessories. This flask from manufacturer Hecht is intended for teaching, quality-control and research laboratories that rely on standardised joint glassware and the thermal and chemical resistance of borosilicate 3.3. Clear white lettering supports quick identification on crowded benches. Offered in a multi-piece pack, it is a practical stock item for routine glassware inventories where small pointed flasks with NS 14/23 joints are needed.
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 Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
