Description
CENTRIFUGE CHASSIS
HOUSING
The centrifuge housing is made of sheet steel and is finished with
urethane paint. The control panel overlay is made of coated
polycarbonate.
DOOR
The steel door is secured to the housing by solid hinges. When the
door is closed, a motorized 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 on the [
OPEN DOOR
] key is lit. If there
is a power failure, the door lock can be manually tripped for sample
recovery (see Section 4, Troubleshooting).
ROTOR CHAMBER
The rotor chamber is stainless steel for durability and corrosion
resistance. The chamber is sealed by a silicone rubber gasket.
TEMPERATURE SENSING AND CONTROL
With the power on, the temperature control system is activated when
the door is closed and locked. Run temperature can be set between
–20 and +40°C. If no set temperature is entered, the instrument auto-
matically selects the last entered temperature.
A sensor in the rotor chamber continuously monitors chamber
temperature. The microprocessor calculates the required chamber
temperature to maintain the selected rotor temperature.
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.
