Figure 2-1. Model SHKE8000-7 Incubated/Refrigerated Stackable Shaker
The incubated and incubated/refrigerated orbital stackable shaker models
are microprocessor-controlled and designed to accommodate a wide variety
of flasks, test tubes and other glassware. The control system is easily
programmed and stores the user-defined time, temperature and speed
settings in battery-supported memory which remains even when the shaker
is turned off and unplugged.
The platform speed controller continuously adjusts for line voltage
fluctuations and provides smooth transitions with consistent control. The
circuitry is designed to slowly bring the platform up to speed and down to
a stop to prevent splashing from flasks or test tubes.
Important Refrigerated models only - Line Frequency Switch must be set
to the correct mains line frequency before power is applied. Figure 1-4
shows switch location.
The insulated door with viewing port has pneumatic dampers and spring
assist for ease in opening and closing. A safety interlock requires that the
door be closed for the drive motor, circulating fans and temperature
control system to operate.
Caution It may take up to one minute to bring the platform up to full
speed. Never leave the shaker unattended while starting. Make sure all
flasks and test tube racks are firmly seated in the clips. Check the security
of the flask clip and platform attachment screws monthly. Do not operate
the shaker at maximum speed without a load.
Warning Do not load or unload the platform until it has come to a
s
complete stop.
