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 initial filling
Before starting the process loops evaporation – filling –
draining, the system can be initially filled.
An initial filling ensures that a minimum quantity is filled
before starting the evaporation, avoiding thus the recrystal-
lization of the educt.
▪ Selection switch in position
▪ Selection switch in position
for the initial filling in the selection field (adjustment via
plus/minus keys).
on off
Touch the / icon to toggle between the two options.
Filling time setting
Adjust the filling time as required using the plus/minus
keys.
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
ration step.
▪ Selection switch in position
for the one additional evaporation step in the selection
field (adjustment via plus/minus keys).
on off
Touch the / icon to toggle between the two options.
Residue draining time
▪ Selection switch in position
time.
▪ Selection switch in position
draining time in the selection field (adjustment via plus/
minus keys).
on off
Touch the / icon to toggle between the two options.
Distillate draining time
▪ In the selection field, define a distillate draining time
(adjustment via plus/minus keys).
