Beschrijving
Pear-shaped flask with standard ground joint, without stopper, made of Boro 3.3 glass with white inscription and conforming to DIN 12383. This laboratory vessel has a nominal volume of 100 ml and a female ground joint NS 29/32 for reliable connection to matching stoppers, adapters or condensers. The tapered pear shape concentrates residual liquid at the base, which is useful for evaporations, small-scale distillations and recovery of limited sample volumes. Supplied without a stopper, the open joint leaves the user free to select the closure or accessory required for each workflow. Boro 3.3 glass offers the chemical resistance and thermal behaviour expected in routine wet-chemistry and organic synthesis work. Clear white inscription supports quick identification on the bench. Packaged in units of 10 pieces and available from manufacturer Hecht, these flasks fit standardised European joint systems and are suited to analytical sample preparation, teaching laboratories and general preparative chemistry where a compact pear form and DIN-compliant ground joint are preferred.
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.
