Executing Methods mode
The interface unit provides the facility for programming a sequence of up to 12 steps
with defined times and parameters. Up to 30 methods can be created. In Methods op-
erating mode, automatic distillation is not possible.
The following steps can be programmed:
Step
Possible settings
Gradient
In this mode, the following process parameters can be defined:
Initial vacuum
Terminal vacuum
Timer
Rotation
Heating bath
Recirculating Chiller
On start: immerse flask
On finish: lift out flask
On finish: Aerate system
The initial and terminal vacuum settings can be identical, e.g. to
prevent foam formation with natural products. Alternatively, the
foam sensor can be used.
Paused
A message can be selected that is to be displayed when the previ-
ous step is stopped:
Remove the receiving flask
Remove the evaporating flask
Clean condenser
Fit bath cover
Clean system
Fit receiving flask
Fit dry receiving flask
Replenish solvent
Transfer contents to drying flask
Fit dry evaporating flask
The subsequent step has to be started manually.
