automatically (to avoid delays in boiling),
- At 80% of the selected maximum speed: the stop valve opens the
connection to the vacuum pump,
- Further speed increase until the preselected maximum rotor speed
is reached.
7. Interrupting an evaporation process:

pump, the aeration valve opens; the rotor speed is maintained for 30
sec (aeration phase, to avoid delays in boiling).
