Use the formula:
n = admissible speed

n = maximum speed
max
Once the rotor has been properly installed, the main switch turned on and the centrifuge door closed, you
may start centrifuging.
Use of Tubes and Consumables
Care should be taken to ensure that the tubes and bottles used in the centrifuge are:
• Rated to or above the selected RCF to be spun at;
• They are being used at or above there minimum fill volume.
• They are not being used above their design life (age or number of runs).
• They are inspected for damage.
Refer to the manufacturers data sheets for further information.
Starting the Centrifuge Run
Press the START key on the control panel. The centrifuge accelerates to the pre-set speed with the time
display active.
If the speed setting is higher than the maximum permissible speed or RCF-value for the particular rotor, then
after starting the display will show the message "Limit" – followed by the maximum RPM- or RCF-value of
the inserted rotor once the centrifuge has been started.
Within 10 seconds of the error message it is possible to accept the highest RPM / RCF of the inserted rotor
by pressing START. The centrifuge will then continue run for the set time and at the set temperature. If no
action is taken within 10 seconds, the centrifuge will continue to decelerate. A new speed setting can be
selected using the SPEED arrow keys and has to be confirmed by pressing the START key.
If no action is taken, the centrifuge will decelerate until stop, then the lid should be opened, and the rotor
checked.
Imbalance Indicator
The centrifuge is fitted with an imbalance detector, to ensure safety. If an imbalance is detected at speeds
higher than approx. 300 rpm, an error message "Imbalance load" will be displayed.
Imbalance at high speed may indicate a tube breakage or leak or rotor crash. Therefore, additional care
should be taken depending on the samples loaded.
The run will terminate.
Once the run is complete, the rotor and load should be checked, ensuring that all buckets are greased and
can swing free and that the tubes are balanced by following the rotor instruction manual.
