HOLD
Press the
key in order to select the HOLD run. During continuous operation, the centrifuge will
continue running until you stop it manually with the
key.
Preselecting the temperature
You can preselect temperatures between -10° C and +40° C.
1. Press the
key in order to enter the temperature.
Note
If an extremely low RCF value has been selected, it will be corrected automatically if the
resulting speed is less than 300 rpm. This is because 300 rpm is the lowest selectable speed.
Explanation of RCF Value
The relative centrifugal force is given as a multiple of the force of gravity g. It is a unitless numerical
value which is used to compare the separation or sedimentation capacity of various devices, since it
is independent of the type of device. Only the centrifuging radius and the speed come into play in
it:
r = centrifuging radius in cm
n = Rotational speed in rpm
The maximum RCF value is related to the maximum radius of the tube opening.
Remember that this value is reduced depending on the tubes and adapters used.
This can be accounted for in the calculation above if required.
