Description
NAME RATING PLATE
The name rating plate is affixed to the rear of the centrifuge. Check
that the line voltage agrees with the voltage listed on this name rating
plate before connecting the centrifuge. Always mention the serial
number and the model number shown when corresponding with
Beckman Coulter regarding your centrifuge (the serial number is also
on the inside of the door).
CHASSIS
HOUSING
The centrifuge housing is made of sheet steel over a steel chassis and
is finished with acrylic baking enamel. The control panel overlay is
made of coated polycarbonate. Polyvinyl chloride and polyester foam
panels line the interior walls of the centrifuge housing for sound and
temperature insulation.
DOOR
The structural steel door has a strobe port for speed verification.
In nonrefrigerated models, the door has two filtered air-intake
ports for rotor cooling. An electromechanical door lock system,
together with a manual lock, prevents run initiation unless the door
is closed and latched. When a run is in progress, the door locks
automatically and can not be opened unless the power is on, the rotor
is virtually stopped (spinning less than 40 rpm), and the manual lock
is in the UNLOCK position. If there is a power failure, the door
lock can be manually tripped for sample recovery (see Section 4,
TROUBLESHOOTING
).
ROTOR CHAMBER
The aluminum rotor chamber (Figure 1-2) is coated with a chemical-
resistant epoxy finish. The drive shaft and neoprene rubber boot
surrounding the drive shaft are visible in the chamber bottom. A
neoprene gasket around the chamber top assures sealing. (Centrifuge
gaskets have not been designed as bioseals for aerosol containment.)
The thermistor is also visible in refrigerated models.
