Distillation Flasks

Distillation flasks are borosilicate glass vessels for heating and separating liquid mixtures by vapour–condensate cycling. Styles include round-bottom and pear-shaped forms, typically with a side-arm and standard ground-glass joints for secure connection to condensers and receivers. Borosilicate construction provides chemical resistance and thermal stability for use with mantles or hotplates. Available in common capacities and joint sizes for preparative and teaching laboratories.
