The temperature systems are designed for temperature
application to closed, external systems (loop circuits). The
temperature application of external, open systems is also
possible. However, this requires a series of special measures
which Julabo cannot influence like e.g. the protection of the
bath liquid from environmental influences such as oxygen and
air humidity.
To profit from the system's rapid performance, ensure the
tubing line between the temperature system and the connected
external system is as short as only possible.
Temperature application to external closed systems.
 Remove the cap nuts from the pump connectors
(10, 11) and using tubing connect the external system
(M24x1.5 / wrench 27 mm).
To prevent the formation of bubbles in the loop circuit, the
pressure line (10) is to be connected to the lower nozzle of
the external system.
 Important:
Connect a piece of tubing to the overflow connector (12)
and drain into a suitable vessel. (M16x1 / wrench 19 mm),
which always has to be placed lower than the exit
„Overflow“.
Notice: Leakage on shaft sealing
The shaft sealings of the pump are never absolutely tight. But this does not have an impact on
the proper functioning of the instrument. The slight leakage that appears ensures good sliding
properties of the sealing. Any excess fluid is drained via the overflow connector (12).
