the cooling path. Depending on the used setup this can either be subsequently at or after the last
condenser.

In case the Rotavapor is not equipped with a vacuum controller a blind cap must be used to close
the vacuum controller connector to achieve a tight setup. The vapor temperature sensor always has
to be installed before the vapor inlet of the first condenser.
