u
Connect a tube between the Rotavapor R-300 and the top inlet of the Woulff bot-
tle.
u
Connect a tube between the outlet of the Woulff bottle marked PUMP (4) and the
pump inlet (3).
u
Connect the secondary condenser to the pump outlet (2).
u
For measuring and controlling the vacuum, connect a tube between the inlet of the
Woulff bottle marked CONTR (5) and the VacuBox (6).
The pressure is measured in the VacuBox. The current working pressure can be indi-
cated and controlled by means of the Interface I-300/I-300 Pro.
NOTE
The VacuBox and Woulff bottle can be mounted either on the Rotavapor R-300 or
the Vacuum Pump V-300/V-600. What is important is that the VacuBox and Woulff
bottle are as close as possible to each other (on the same device) as otherwise there
is a vacuum control lag.
NOTE
Connections on R-220 Pro:
Information on the connection of communication cables, coolant and vacuum tubing
with the Rotavapor R-220 Pro can be found in the operating instructions for the Ro-
tavapor R-220 Pro.
