4 .1 Functional principle of a Rotavapor
With a Rotavapor, single step distillations are performed quickly and in a product friendly manner.
The basis of this procedure is the evaporation and condensation of solvents using a rotating evapo-
rating flask under vacuum. Distilling products under vacuum increases the performance and helps to
protect the products.
