Description

Temperature Control
The temperature control system cools by circulation of a non-CFC-based refrigerant. The system is
activated when the centrifuge power is on and when the door is closed and latched.
A thermistor in the rotor chamber continuously monitors the chamber temperature. The system
calculates the chamber temperature required to maintain the set rotor temperature, ±2°C.
Although the chamber temperature fluctuates during operation, the rotor’s large mass keeps the
sample temperature substantially constant. At the end of a run, the system continues controlling
the temperature for 30 minutes to prevent freezing or overheating of the sample.
NOTE
The system will always shut down using maximum brake if the temperature goes above 50°C.
Drive
The drive shaft is belt driven by a brushless, high-torque, switched-reluctance motor. The
instrument’s resilient suspension minimizes disturbance of the sample during acceleration and
deceleration, and reduces damage to the drive shaft if an imbalance occurs during centrifugation.
Name Rating Plate
A name rating plate is affixed to the rear of the instrument. Always mention the serial number and
model number when contacting Beckman Coulter regarding your Avanti J-E centrifuge.
Controls and Indicators
Power Switch
The power switch, located on the right panel 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.
Control Panel
The control panel (see Figure 1.2) is mounted at an angle on the centrifuge front for easy visibility
and access. It is used to enter run parameters via function keys and a keypad, and to display run
parameters, program information, and user messages.
