6.2.3
Distillation with timer function
The set point of system pressure and distillation duration are
input. When the distillation starts, the system pressure is
reduced to the input value and kept constant during the
selected period. At the end of the input distillation time, the
distillation is stopped. If so configured, rotation of the rotary
evaporator is stopped and the flask is lifted from the bath.
6.2.4
AUTODEST function (only with automatic
dual temperature sensor)
Allows full automatic distillation without input of parameters until
dryness, if physically possible. As soon as the evaporating flask
is dry, distillation is stopped. If so configured, rotation of the
evaporating flask is stopped and the flask is lifted from the bath.
6.2.5
The TEMPERATURE function (only with
automatic dual temperature sensor)
Distillation is carried out on the automatically found pressure.
As soon as the vapour temperature drops, distillation is
stopped. If so configured, rotation of the evaporating flask is
stopped and the flask is lifted from the bath.
6.2.6
The REPEAT function
The last, for example, manually performed distillation can be
repeated and stored for later use (learning by doing). This is a
valuable function for difficult distillations, which must be
performed repeatedly, in which the parameters must be
experimentally determined and optimised.
6.2.7
Working memory
The last mode used and associated values are kept in the
working memory after the apparatus is turned off and are
automatically recalled when the apparatus is turned back on.
6.2.8
Memory of methods
Memory for 5 complete distillation programs. Memory
management with the help of conventional functions,
Storing,
Retrieving, and Deleting.
