This glassware from manufacturer Witeg supports synthesis, heating under reflux, solvent handling and related laboratory processes that rely on an NS 29/32 joint. Clear glass allows straightforward observation of contents during reactions or transfers. Suitable for teaching, research and industrial laboratories seeking a short-neck borosilicate 3.3 round-bottom flask in the 150 ml size with standard NS 29/32 connectivity for everyday chemical work.

Questions about Round bottom flask 150 ml ST 29/32 Economy
What is this article?
Round bottom flask 150 ml ST 29/32 Economy is the article on this page. Luminix Health distributes Witeg 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.
