5 Operating the Rotavapor
Make sure that the Rotavapor was installed correctly as per
the instructions in Chapter 4, «Putting into operation».
If the power switch is turned on, all functions will be active as
soon as the power plug is inserted. To prevent damage, set
the rotation controller and the heater to «0».

5.2 Performing a distillation run
In the following section we shall describe how to start, optimize
and end a distillation run on the basis of a checklist.
1. Rotavapor fully installed
All the electrical connections correct (power cable, heater).
All the seals properly installed.
All the ground-glass joints greased.
Evaporation flask attached.
2. Evacuate the Rotavapor to test for leaks.
Leak test as described in Chapter 6.2, Function test (< 3
mbar pressure rise / min.).
3. Set heating bath to 60 °C
4. Water in bath has reached a temperature of 60 °C
5. Cooling water
Have cooling water flow through the condenser at a rate of
approx. 40–50 l/h and at a temperature not higher than
20°C
