Door
The aluminum and structural foam door is secured to the housing by solid hinges. A window in the
center allows strobe viewing. When the door is closed, the locking system engages. The door is
locked when a run is in progress and can be opened only when the rotor is stopped and the LED next
to the
DOOR
key is lit. If there is a power failure, the door lock can be manually tripped for sample
recovery (see
CHAPTER 3,
Troubleshooting
).
Rotor Chamber
The aluminum rotor chamber is coated with epoxy enamel for corrosion resistance. The chamber
is sealed by a foam gasket.
Temperature Sensing and Control
With the power on, the temperature control system is activated when the door is closed and locked.
A sensor in the rotor chamber continuously monitors chamber temperature. The microprocessor
calculates the required chamber temperature to maintain the selected rotor temperature. Run
temperature can be set between 2 and +40°C.
NOTE
To avoid chamber icing, refrigeration is off when the door is open. The centrifuge door must be closed
and locked for the refrigeration system to begin operating.
Drive
The asynchronous direct-drive motor is brushless for clean, quiet operation. The resilient
suspension ensures that loads will not be disturbed by vibration, and prevents damage to the drive
shaft if an imbalance occurs during centrifugation. Maximum acceleration and deceleration may be
selected to allow fast processing of samples; alternately, delicate gradients may be preserved using
slower acceleration and deceleration.
Controls and Indicators
Power Switch
The power switch, located on the left side of the centrifuge, controls electrical power to the
centrifuge. It is also a circuit breaker that will trip to cut off power in the event of a power overload.
The power switch must be turned on before the chamber door can be opened.
