5.1 Tips for shaker operation
Please note that the device restarts automatically when power is supplied
again after an interruption.
We recommend to find out the most superior shaking behaviour by means
of a reference microtiter plate. The shaking behaviour is influenced by the
shaking frequency and the shaking power
. Please test which shaking
frequency results in a maximum vortex movement without striking the
shaker platform (4). The most efficient operation is insured by a frequency
just below the resonance
Standard values:
-
The resonance frequency depends on the weight of the system
consisting of shaker platform (4) + microtiter plate + liquid.
-
Without load, the resonance frequency is at approximately 7,200 rpm.
-
If the magnetic shaker is loaded with an unprepped 1536 MTP, the
resonance frequency is at approximately 6,200 rpm.
-
The heavier the weight, the lower the resonance frequency.
-
The higher the selected shaking power (see also Remote operation,
Chapter 6), the larger the amplitude of the shaking movement.

The shaking power determines the amplitude of the shaking movement.

When the magnetic shaker operates at resonance frequency, it only executes a
longitudinal movement.
