Supporting the Flask While Heating
A round base will not stand on a flat bench by itself. Over a burner or heating mantle, clamp the flask by its neck on a retort stand; when it is set down, rest it in a ring or a rubber flask base. For a simple distillation, fill it to no more than two-thirds and add a few anti-bumping granules so the liquid boils smoothly.
Round or Flat Bottom?
The flat-bottom flask in this series stands on its own and suits open boiling and gas preparation. Choose the round-bottom flask when the contents are heated for a long time or distilled, and when it will be held in a clamp.
