Before A Run; Starting The Centrifugation - Thermo Scientific Sorvall ST 8FR Instruction Manual

Use of Tubes and Consumables
Care should be taken to ensure that the tubes and bottles used in the centrifuge are:
ƒ rated to or above the selected rcf to be spun at,
used at there minimum fill volume,
ƒ
not used above their design life (age or number of runs),
ƒ
undamaged�
ƒ
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�
4� Check the rotor suitability:
5� Make sure that the buckets are in correct position�
Set the parameters for the centrifugation� For details:

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�
