Distillation method
Select between the automatic distillation methods "Volume" and
"100%". This selection only has an effect during auto-distillation.
Volume
The measured values of the cooling water flow rate and the cooling
water temperature difference form the basis for a heat balance calcu-
lation used to determine the quantity of distillate at every stage of the
distillation. The distillation process is halted when the specified quantity
of distillate has been reached.
100%
The distillation process is stopped when the measured cooling water
temperature difference falls below a threshold value, i.e. as soon as a
solvent has been completely distilled off.
Drying
The cooling water temperature difference is not monitored if this option
is activated, e.g. use in processes for drying powdered media.
Heat rejection rate threshold
A limit value can be set for the heat rejection rate that is appropria-
te for the condenser used; see "useful information" section. The actual
heat rejection rate is calculated during every distillation process. If the
threshold is exceeded, the distillation will be stopped and an error mes-
sage displayed.
Maximum heat rejection rate
The maximum heat rejection rate achieved during the last distillation is
displayed. This value is for information purposes only.
Quantity meas. unit
Select between millilitre and gram as the unit of quantity.
Boiling point recognition
Boiling point recognition can be either activated or deactivated. Boiling
point recognition is only possible in "100%" mode for the distillation
method.
The boiling point recognition function automatically detects the boiling
point of a solvent.

Hysteresis
The default settings for the hysteresis (as shown) are suitable for use in
most situations. The (vacuum) hysteresis value describes the difference
between the closing and opening pressures for the vacuum valve.
Time scaling
The time axis of the vacuum-rotation-time graph is scaled using the value
specified here. If the value = 0, then the time axis is scaled automatically.
Vacuum scaling
The vacuum axis of the vacuum-rotation-time graph is scaled using the
value specified here. If the value = 0, then the vacuum axis is scaled
automatically.
Vacuum meas. unit
Select between the units of measurement for a vacuum: mBar, Torr, and
hPascal.
