Opening the lid
The lid can only be opened if the rotor is at a standstill. It is not possible to
open the lid during an evaporation process
DANGER
During the evaporation process, the housing, lid and interior of the
rotational vacuum concentrator can reach surface temperatures of more
than +50°C.
Risk of burns!
Warm-up
Before starting an evaporation process, the vacuum pump and the cooling
trap should warm-up until they reach their respective operating
temperatures.
For this purpose, the warm-up phase can be started with or without a rotor.
The time and the temperature can be preselected (see chapter 6.5.3.3 -
"Options").
During the warm-up phase, the following processes take place:
• The rotor chamber is preheated - with or without a rotor - when the lid is
closed.
• The vacuum pump is switched on, the stop valve is closed. After the
warm-up phase, the following message is displayed:

• Open the lid and remove the rotor in order to load it with the product or
insert the loaded rotor.
