Safety Features
Allegra X-30 Series centrifuges have been designed and tested to operate safely indoors at altitudes
up to 2000 m (6562 ft).
Instrument safety features include:
• The door has an electromechanical door-locking mechanism to prevent operator contact with
spinning rotors. When the door is closed it locks automatically. It can be unlocked only by
pressing the
OPEN DOOR
key, and opened only when the power is on and the rotor is at rest.
Two independent monitoring systems prevent the door from opening if the rotor is spinning.
• A steel barrier surrounds the rotor chamber to provide full operator protection.
• An overspeed system continuously monitors the rotor during centrifugation. The system
includes a magnetic sensor on the drive motor and magnets embedded in the rotors.
Throughout the run, checks are made to ensure that the rotor does not exceed set speed.
• 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 surface.
• The centrifuge feet, made of rubber, have been designed to minimize possible rotation in the
event of a rotor mishap.
Chassis
Housing
The centrifuge housing is made of sheet steel, finished with urethane paint. The control panel is
covered by a protective overlay made of coated polycarbonate.
Door
The door is made of a solid sheet of steel, encased in foam molding. In the center of the door is a
window for strobe viewing. The door is secured to the housing by solid shafts. An electromechanical
door lock system prevents operator contact with spinning rotors and prevents run initiation unless
the door is shut and latched. The door is locked when a run is in progress and can be opened only
when the rotor is stopped. (A light-emitting diode [LED] on the
OPEN DOOR
key lights up when the
door can be opened.) In the event of a power failure, the door lock can be manually released for
sample recovery (see CHAPTER 3, Troubleshooting ).
Rotor Chamber
The rotor chamber is shown in Figure 1.1 . The drive shaft, mounting plate, rubber boot surrounding
the drive shaft, thermistor, and rotor detector are visible in the chamber bottom. A gasket system
around the chamber opening ensures sealing. (Instrument gaskets have not been designed as
bioseals for aerosol containment.)
