Description
Round-bottom flask, 100 ml, socket NS 29/32 is a versatile single-neck laboratory vessel made of borosilicate glass 3.3 for distillation, reflux and general reaction work. Its medium neck is fitted with a standard ground joint NS 29/32, allowing leak-free connection to a wide range of condensers, adapters and other interchangeable glassware. The 100 ml nominal capacity strikes a practical balance between small-scale synthesis and intermediate preparative tasks, while the spherical base promotes even heat distribution and effective mixing. Supplied as one piece with a net weight of 0,062 kg, the flask from manufacturer Rettberg delivers the well-known chemical inertness and thermal-shock resistance of borosilicate glass 3.3. It is equally at home in research, quality-control and educational laboratories that rely on modular ground-joint apparatus for organic and inorganic chemistry applications.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask, 100 ml, socket size 29/32
What is this article?
Round bottom flask, 100 ml, socket size 29/32 is the article on this page. Luminix Health distributes Rettberg 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.
