Running time preselection
1. Press the key
below the TIME display in order to open the runtime selection menu.
The display shows the message "Set Time".
Enter the desired runtime in H.mm.
2. Enter the desired value by pressing the key
repeatedly, until the desired value shows.
Continuous operation
1. Press the START key
.
During continuous operation, the centrifuge will continue running until you stop it manually.
Preselecting the temperature
You can preselect temperatures between -10 °C and +40 °C.
To set the temperature, proceed as follows:
1. Press the key
below the TEMPERATURE display in order to open the temperature selection
menu.
The display shows "Set temp":
2. Enter the desired value by pressing the key
repeatedly, until the desired value shows.
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.
