Function of individual elements
Connecting cable Controller – Rotavapor
The apparatuses are connected together in such a manner,
that, if you so desire, the start/stop of rotation and raising and
lowering of the evaporating flask, can function via the Vacuum
Controller, i.e.:
• When distillation is started via the Vacuum Controller V-
800/805, the evaporating flask moves to the previously
set end catch and rotation is switched on.
• When distillation is stopped via the Vacuum Controller V-
800/805, rotation switches off and the evaporating flask is
raised from the bath.
Valve unit
When the set point on the Vacuum Controller is reached, the
valve unit shuts off the connection to the pump. At the same
time, the valve unit serves as separator, i.e., the pump is
protected against contamination.
Switchbox of V-500
When the set point on Vacuum Controller is reached, the
pump is switched off. If the system pressure increases above
the hysteresis set on the Vacuum Controller, the pump is
switched back on.
Fixation and current supply are only suitable for Büchi Vacuum
Controller V-800 and 805. Older Büchi Controllers or other
Controllers can be mounted on an extra rod and must not be
connected to the power supply of the Rotavapor.
See relevant operating instructions for detailed
information on operation of the Vacuum Controller.
