Safety Features

The Allegra X-14 series centrifuges have been designed and tested to operate safely indoors at
altitudes up to 2000 m (6562 ft). Safety features include the following.
• An electromechanical door lock system prevents operator contact with spinning rotors and
prevents run initiation unless the door is shut and locked. The door is locked when a run is in
progress and can be opened only when the rotor is stopped and the LED (light-emitting diode)
next to the
sample recovery.
• A steel barrier surrounds the rotor chamber to provide full operator protection.
• A rotor identification system prevents the installed rotor from running above its maximum
rated speed. During acceleration the microprocessor checks the magnetic rotor identification.
Speed is limited to the maximum safe speed of the identified rotor. If the system identifies a
rotor different than the one entered by the user, the system displays an error message and
reduces the speed to the maximum allowable speed of the rotor.
• An imbalance detector monitors the rotor during the run, causing automatic shutdown if rotor
loads are severely out of balance. At low speeds, an incorrectly loaded rotor can cause
imbalance. Rotor instability can also occur if the centrifuge is moved while running, or if it is
not resting on a level and secure surface (see

Housing

The centrifuge housing is made of sheet steel and structural foam and is finished with acrylic baking
enamel. The control panel overlay is made of coated polystyrene copolymer.
