Important safety reminder
Certain potentially dangerous conditions are inherent to the use of all centrifuges. To ensure safe
operation of this centrifuge, anyone using it should be aware of all safe practices and take all
precautions described below and throughout these operating instructions.
DANGER
• Before removing any cabinet panel (such as for maintenance or repair), always turn
the main Power Switch OFF and unplug the centrifuge, then wait at least three
minutes to eliminate the potential for severe electric shock.
WARNING
• Never exceed the maximum rated speed of the installed rotor; to do so can cause rotor
failure.
• Always reduce (derate) rotor speed whenever:
1. The rotor speed/temperature combination exceeds the solubility of the gradient
material and causes it to precipitate.
2. The compartment load exceeds the maximum allowable compartment load (or design
mass) specified for your rotor.
Failure to reduce speed under these conditions can cause rotor failure.
• Always inspect the rotor as specified in your rotor manual. Do not use a rotor that
shows signs of damage or corrosion.
• Centrifuges routinely deal with high energy levels and could move suddenly in the
unlikely event of rotor failure. During centrifuge operation, never lean on or move the
centrifuge, keep the surrounding area clear of objects (including all hazardous and
flammable materials), and do not work on top of or next to the centrifuge (as a rule,
keep people and objects at least 300 mm [12 inch] away).
• Never unlock the chamber door, attempt to open the door, or otherwise attempt to
touch the rotor while it is rotating. In the event of a power outage, it can take more
than three hours for the rotor to stop - be sure to wait at least three hours before
opening the door.
• Never attempt to override or otherwise disable any safety features.
• When using radioactive, toxic, or pathogenic materials, be aware of all characteristics
of the materials and the hazards associated with them in the event leakage occurs
during centrifugation. If leakage does occur, neither the centrifuge nor the rotor can
protect you from particles dispersed in the air. To protect yourself, we recommend
additional precautions be taken to prevent exposure to these materials, for example,
use of controlled ventilation or isolation areas.
• Always be aware of the possibility of contamination when using radioactive, toxic, or
pathogenic materials. Take all necessary precautions and use appropriate
decontamination procedures if exposure occurs.
