6.3 Centrifuging notes

• Connect the centrifuge to the mains (master switch on left side of the centrifuge).
• Open the cover of the centrifuge by pressing the COVER key. Prior to putting the rotor in, one has to check if
the rotating chamber is free of impurities, e.g. such as dust, glass splinters, residues of fluids that must be taken
away.
• One shall fit the rotor on the motor shaft driving it home on the cone.
Fitting the rotor too shallow will result in lack of identification of the rotor after start of the centrifuge,
displaying the error message and stopping the centrifuge.
• Screw-in the bolt for fixing the rotor (clockwise) and screw it tightly home with the supplied spanner for the rotor.
• Swing-out rotors have to be provided with the buckets in all seats. One should remember that every buckets
swings individually. Bucket suspension studs should be lubricated periodically with petroleum jelly.
• In case of rotors designed with the cover they must not be used without it. Rotor covers must be closed exactly.
Rotor covers ensure smaller drags of the rotors, proper setting of the test-tubes and airtight sealing.
• One should use only buckets intended for selected types of the rotor.
• Fill test tubes outside the centrifuge.
• Put on or screw the caps on vessels and rotors (if applicable).
• In case of centrifuging in an angle rotor, test tubes (buckets) have to be filled properly in order to avoid overflows.
Centrifuge will tolerate small weight differences occurring during loading of rotors. However, it is
recommended to equalize vessels loads as much as possible in order to ensure minimal vibrations
during operation. When the centrifuge is started with large imbalance, the unbalance control system
will switch-off the drive system and error signal will be transmitted. On the monitoring panel, error
message will be displayed.
• In order to prolong lifetime of the gaskets and threaded parts shall be lubricated with the petroleum jelly
• For replacement of the rotor one shall unscrew clamping and then grab the rotor with both hands at opposite
sides, taking it away from drive shaft by pulling it up.
