adjusted by means of the selection knob when the pump is running or, before operation, via the corresponding menu when pressing the menu button P Set.
4.2.2
Timer mode
The Timer mode serves to control the pressure over a predefined time interval. When the time interval
is over, the process stops.
4.2.3
AutoDest mode (V-855 only)
The AutoDest mode serves to carry out an automatic distillation based on a temperature differences
within the condenser. Thanks to the AutoDest probe mixtures can be distilled gently and automatically
and the redistillation is recognized.

4.2.4
Description of function
EasyVac mode (V-855 only)
The EasyVac mode serves to carry out an automatic distillation based on the vapor pressure of the
solvent. The process is started at the push of a button and the start point of the distillation is found
automatically. Then the pressure is adapted according to the vapor pressure curve and the end point
of the distillation is determined. Based on sophisticated algorithms the process is executed in a
robust, gentle way. This mode is suited for distilling single solvents.

The Gradient mode serves to define up to 15 programs in the most complex way, step by step. For a
description of how to define programs, see chapter 6.7.3.
4.2.6
Repeat mode (V-855 only)
The Repeat mode serves to reproduce a distillation: The pressure course of the last distillation carried
out manually or automatically can be saved and reused as setpoint setting to supply optimum process
conditions.

4.2.7
Description of function
LabVac mode (V-855 only)
The LabVac mode serves to control the pump within a laboratory vacuum system.
The pump operation is switched off when the vacuum has reached the lowest possible value and is
switched on again when the pressure has increased by a preset value (hysteresis [dp]). The pump
operation is also switched on, as soon as a load is present in the vacuum system.
When the menu button CONT. is pressed the pump operates in Continuous mode to obtain a vacuum
as low as possible independent of the connected load.
NOTE
EasyVac and the Autodistillation function are not recommended to be used in the standard LabVac
mode due to pressure fluctuations (hysteresis). Therefore you have to run the LabVac system in the
Continuous mode.

On the AutoDest parameter screen you can
define several parameters for auto distillation:
• Low boiling det.: Warm-up time for evaporating flask. The default value is 20 s. For
sample volumes of more than 2 l, we recommend to increase the value by ca. 10 s.
• Aspiration time: Time interval after which
a new pressure setpoint has to be reached
(the pressure setpoints are predefined within
the system). This value must be adapted
according to the pump performance. The
default value is 5 s. We recommend to
increase the value for pumps with a low aspiration capacity, i.e. water jet pumps, or when
the error message “Because of a leak the
distillation process was cancelled” appears.

Selecting the distillation conditions
To achieve optimal distillation conditions, the distillation energy supplied by the heating bath must be
removed by the condenser.
To ensure this, operate the instrument according to the following rule of thumb:
Cooling water: max. 20 °C
Vapor: 40 °C
Bath: 60 °C
How are these conditions achieved?:
• Set the bath temperature to 60 °C.
• Set the cooling water temperature not higher than 20 °C.
• Allow cooling water to flow through the condenser at approximately 40 – 50 l/h.
• Define the operating vacuum in such a way, that the boiling point of the solvent is 40 °C. The corresponding pressure can be seen from the Solvent Table in chapter 3.
Advantages associated with bath temperatures of 60 °C:
• The evaporating flask can be replaced without risk of burns.
• The evaporation rate of the water from the heating bath is low (low energy loss).
• The heating bath energy is used at a good degree of efficiency.
This rule can also be applied to lower bath temperatures, e.g.:
Cooling water: 0 °C

Vapor: 20 °C
Bath: 40 °C

Operation
When you are not working with a Vacuum Pump V-700/710, the following screen appears:
The hysteresis is needed for a precise pressure regulation by means of the vacuum control
valve.
When the Vacuum Pump V-700/710 is not
used, no automatic frequency control is
provided.
Fig. 6.5: Pressure setpoint without Vacuum Pump V-700/710
Use the selection knob of the vacuum controller to define the pressure setpoint and the hysteresis, if
applicable, for your evaporation process. Turn the knob to the right to increase the value or to the left
to deminish the value and confirm your setting(s) with OK.
NOTE
To find out, which settings are appropriate for your solvent, consult the solvent library, see chapter
6.4.2.
When you press ESC, the screen changes to the original setting, i.e. to the previous setpoint.
• Press the START button to start the destillation process or to return to the main screen.
ATTENTION
Risk of overflowing.
• With a controller configured in a way that the flask is immersed automatically into the heating
bath, make sure that the heating bath is only filled up to a level which cannot overflow in this case.
• Track the system pressure by means of the selection knob at the vacuum controller as needed.
• To stop the process, press the STOP button. The evaporating flask stops rotating and is removed
from the heating bath automatically, if configured accordingly.
NOTE
Depending on whether you have selected Aeration On/Off in the Options controller, the system is
either aerated directly after the STOP button was pressed (Aeration ON) or when the STOP button is
