Orbital Shaker 2-1 Thermo Scientific
Section 2
Operation
The MaxQ SHKE420HP is a microprocessor-controlled benchtop orbital
shaker 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 setting which remain in memory
even when the shaker is turned off and unplugged.
The computer-based speed controller continuously adjusts for line voltage
fluctuations and provides smooth start-ups and consistent RPM control.
The circuitry is designed to slowly bring the platform up to speed and
down to a stop to prevent liquid splashing from flasks or test tubes. A
convenience interlock requires that the lid be closed for the drive motor,
circulating fans and heating elements to operate.
• The microprocessor speed control system may take up to one minute
to bring the platform up to speed.
• Never leave the shaker unattended when starting it. Make sure all
flasks and test tube racks are firmly seated in the clips and check the
security of the flask clip and platform attachment screws monthly.
• The lid must be closed to operate the shaker.
• Do not operate the shaker at maximum RPM without a load.
