Product Overview
Abdominal vessels are called flasks in the laboratory and, in addition to beakers, are other universally applicable vessels. They are used e.g. for distillation or for heating liquids.
Flasks are available in various designs: narrow and wide neck, with or without ground joint, as round or flat bottom flask. Depending on the application, the required flask with its specific components is selected. Due to their spherical shape, round bottom flasks are used for heating liquids, among other things.
