This chapter explains the basic principle of the instrument, shows how it is structured and gives a
functional description of the assemblies and accessories.
4.1 Vacuum pump
4.1.1 Functional principle
The Vacuum Pump V-700/710 serves to evacuate laboratory instruments down to 10 mbar respectively 2 mbar pressure by means of a PTFE diaphragm pump. This pump is controlled by a variable
speed and single stroke technology.
It can be either used as stand-alone instrument or it can be expanded to a complete vacuum system
with optional accessories such as vacuum controllers and a secondary condenser.
NOTE
During a stable vacuum control irregular pump motor operation might be audible when the pump is
in the change over between speed control and Wankel operation. This is absolutely normal and does
not indicate a technical malfunction.

4.1.4 Gas ballast
The gas ballast serves to aerate the system (membrane and valves) during pump operation, thus
avoiding the collection of condensed solvent within the system.
NOTE
The end vacuum is reduced to about 24 mbar when the gas ballast is open. The air stream due to
the open gas ballast dries wet membranes, therefore close the gas ballast when the membranes are
dry to reach a low end vacuum.

a Start
By pressing the START button the pump starts evacuating the system until the solvent in the evapo-
rating flask starts boiling. 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.
Continuous
By pressing the START button for more than 2 seconds, the pump enters the Continuous mode,
where it operates constantly.
b Stop
When pressing the STOP button the pump stops and the system is aerated by means of the valve at

• LED flashes: The system is in Continuous mode
d LED PROCESS STATUS
• Permanent light: The system has reached the possible end vacuum
• LED flashes: The system searches the constant end vacuum
4.5 ECO2 Mode
The ECO2 Mode only becomes active when the Vacuum Pump V-700/710 is operated as stand-alone
system, i.e. without a vacuum controller.
The ECO² Mode works as follows:
• During the first hour of operation the pump operates at a speed of 100%.
• After one hour of operation without interruption the pump automatically reduces its speed to 80%
and operates at this speed for another hour. The end vacuum of 10 mbar (V-700) or 2 mbar
(V-710) is not affected by this action, only the evacuation speed is reduced.
• After a total time of two hours of constant operation the pump reduces its speed again to 50% of
its total capacity. The end vacuum of 10 mbar (V-700) or 2 mbar (V-710) is again not affected by
this action, only the evacuation speed is reduced.
• If the pump is switched off and on again, it starts at its full speed and will change to the ECO²
Mode after one hour of constant operation (see above).

NOTE
The new ECO² Mode only reduces the suction power. The end vacuum is not affected.

6 Operation
This chapter explains the operating elements and possible operating modes. It gives instructions on
how to operate the instrument properly and safely.
ATTENTION
Check the glassware for damages prior to each operation and use only glassware in perfect condition. Glassware with cracks, stars or other damages can break during operation.
6.1 Starting the pump
6.1.1 Pump without controller
After the pump is completely installed it is ready to operate, i.e. when the mains switch is pressed, the
pump starts operating right away and starts evacuating until the end vacuum (10 mbar with the V-700
and 2 mbar with the V-710). When the pump is operated continuously over a longer period of time it
automatically switches to the ECO² Mode (see chapter 4.5). In case the Vacuum Pump V-700 or V710 is part of a central lab source pump we recommend to use the Vacuum Module V-802 LabVac to
ensure an unreduced suction power during the whole operation time (see chapter 4.4).
6 Operation
6.1.2 Pump with controller
After the pump and the controller are completely installed, the system is ready to operate. When the
mains switch is pressed, the pump is on standby and starts operating as soon as the controller is
started. It then evacuates to the vacuum preset at the controller.
6.1.3 EasyVac

6.2 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: >1.2 l/min (continuous not pulsed).
• Define the operating vacuum in such a way, that the boiling point of the solvent is 40 °C. The corre-
sponding 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

40V-700/710 Operation Manual, Version E
6.3 Optimizing the distillation conditions
Depending on the solvent being distilled the distillation might have to be re-optimized. In the optimized
case, the condenser should be steamed up to between 2/3 to 3/4, see figure below.
If this is not the case, there are two possibilities to optimize the distillation:
• When the heating bath has reached 60 °C slowly reduce the pressure. Thus, the boiling point of
the solvent is reduced and Δ T
• When the heating bath has reached 60 °C increase the bath temperature. Thus Δ T
resulting in an increase of distillation capacity as well.
NOTE
When the bath temperature is increased, not all of the additional energy is used for distillation but a
major part is discharged into the environment due to the increasing difference between heating bath
and the ambient temperature.

Immediate maintenance
The housing is made of plastic. Remove any acid drops immediately from the housing with a moist
cloth.
General maintenance
Check the housing for defects (controls, plugs) and clean it regularly with a moist cloth.
ATTENTION
Never use organic solutions (except for ethanol) as cleaning agents as these might damage the
instrument.
7.2 Glass parts
Rinse the glass parts regularly with standard cleaning agents (e.g. mild soap solutions).
Afterwards examine them visually for splintered parts or cracks.
ATTENTION
Check the glassware for damages prior to each operation and use only glassware that is in perfect
condition. Glassware with cracks, stars or other damages can break during operation.
7.3 Hoses and gaskets

7.4 Valve head
7.4.1 Cleaning
If the end vacuum of 10 mbar is not reached anymore and the rest of the system has no leakage, the
problem is often caused by stuck valve plates.
To clean them, proceed as follows:
• Remove all connections to the pump and to the silencer.
• Switch the pump on.
• Inject a small amount of about approx. 10 ml of acetone at once into the inlet side of the pump and
wait until the pump makes the same sound as before injecting solvent.
NOTE
Use safety washing bottles to inject the acetone, as shown in Fig. 7.1.
• Repeat the injection step four to five times.
• Let the pump run for about 2 minutes and check whether the end vacuum can be reached.
• If this is still not the case, repeat the cleaning procedure before going on with any disassembly
work.
