    4 Description of function Description of function This chapter explains the basic principle of the instrument, shows how it is structured and gives a functional description of the assemblies. 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.
  • Page 22 4 Description of function a Evaporation area The solvent is heated by means of a heating bath. A thin solvent film forms on the inside of the rotating evaporating flask, resulting in an increased evaporation rate. The rotations also lead to an even mixing of the sample thus preventing stationary overheating in the flask.

    5 Putting into operation Saving energy For heating baths there are various ways to save energy. By using floating balls in the water bath, evaporation of water is reduced. As a result, the bath heating has to switch on less often. This measure helps to save up to 50 % of energy.

    5 Putting into operation ATTENTION The support rod is not designed to carry the weight of the glass assembly on its own. Its sole purpose is to stop the glass assembly tilting forward or backwards when the flanged coupling is released.

  • Page 31: Vacuum Tubes

    • The tubes used must all have the same inner diameter (approximately 5 mm). • Keep vacuum tubes as short as possible. • When you are operating with the new BUCHI Vacuum Controller V-850/V-855 and Vacuum Pump V-700/V-710 connect a Woulff bottle between the vacuum source and the Rotavapor.
