medium when the flask is rotating and from pieces of broken glass
in the unlikely event of an implosion of the evaporating flask.

4 .6 Woulff bottle
The Woulff bottle serves as safety vessel between the Rotavapor
and the vacuum pump. In case of an impure distillation the
condensate is collected in the Woulff bottle and thus cannot
reach the pump.
