Closing the rotor lid (aerosol-tight centrifugation)
Identification of aerosol-tight rotors
An aerosol-tight rotor and the matching aerosol-tight rotor lid must be used for aerosol-tight centrifugation.
Aerosol-tight fixed-angle rotor
• Designation ends with AT
Aerosol-tight rotor lid
• Labeled aerosol-tight

Centrifugation
Prerequisites
• The centrifuge is switched on.
• The rotor has been inserted and attached correctly.
• The rotor has been loaded correctly.
• The rotor lid has been mounted correctly.
• The centrifuge lid is closed.
WARNING! Risk of injury from improperly attached rotors and rotor lids.
Only centrifuge with the rotor and rotor lid firmly tightened.
If unusual noises occur when the centrifuge starts, the rotor or rotor lid may not be properly secured.
Immediately press the STOP/OPEN key to stop centrifuging.
5.6.1
Centrifugation with time setting
Setting the centrifugation parameters
1. Set the centrifugation time with the TIME arrow keys.
2. Set the rotational speed (rpm) or g-force (rcf) with the SPEED arrow keys.
Starting the centrifugation run
3. To start the centrifugation run, press the START key.
Display during centrifugation
• The
symbol is flashing when the rotor is running.
• Remaining run time in minutes. The last minute is counted down in seconds.
• Current g-force (rcf) and/or rotational speed (rpm).
During the run you can change the following parameters:
• Centrifugation time
• Speed: During the run, you can switch between the g-force and the rotational speed (rpm) using the RPM/RCF key.
The following keys are blocked during centrifugation:
• SHORT key
1. Check the correct positioning of the external
sealing ring in the groove.
2. Place the rotor lid on the rotor in a vertical motion.
3. Turn the rotor lid screw clockwise until it stops to seal the rotor.
Switch the centrifugation speed display using
the RPM/RCF key.
