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,
used at there minimum fill volume,
not used above their design life (age or number of runs),
undamaged�
Refer to the manufacturers data sheets for further information�
Before a Run
1�
Read and observe the precautions and the safety instructions in this instruction manual�
As safety zone maintain a clear radius of at least 30 cm around the centrifuge�
Stay out of the safety zone during centrifugation� Do not place any dangerous substances
within this safety zone� Implement measures which ensure that no one can approach the
centrifuge for longer than absolutely necessary while it is running�
2�
Check the rotor and all accessories for damages such as cracks or scratches�
3�
Check the centrifugation chamber and the centrifuge drive�

Starting the Centrifugation
Press the START key on the control panel� The centrifuge accelerates to the 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 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 decelerate until the rotor
is stopped� The speed will be automatically set to the maximum speed of the installed rotor� The
message can only be reset by opening the centrifuge door�
If no action is taken, the centrifuge will decelerate until stop, then the centrifuge door should be
opened and the rotor checked�
