Function
Adjustable time for the pre-evacuation phase
Before starting the process loops evaporation – filling –
draining, the system is pre-evacuated for the time set here.
Adjustable time for the initial filling
Before starting the process loops consisting of evaporation
– filling – draining, the system can be filled initially.
An initial fill ensures that the process is started with
minimum quantity, thus avoiding possible recrystallization.
▪ Selection switch in position
▪ Selection switch in
for the initial filling in the selection field (adjustment via
plus/minus buttons or tap/on-screen keyboard).

Touch the / icon to switch between the two options.
Filling time setting
Adjust the filling time as required using the plus/minus
buttons.
Evaporation time setting
Adjust the evaporation time as required using the plus/
minus buttons.
Additional evaporation step to reach a specific end
concentration
Activate this option to pass an additional evaporation step
after passing through the process loops to achieve a desired
end concentration or to remove any residual moisture from
the residue in solid-liquid mixtures.
▪ Selection switch in position

▪ Selection switch in
for one additional evaporation step (adjustment via plus/
