Housing And Door; Rotor Chamber - Beckman Coulter Avanti J-25 Instruction Manual

HOUSING AND DOOR

ROTOR CHAMBER

• A steel casing surrounds the rotor chamber to provide operator
protection in the unlikely event of a rotor mishap.
• Dynamic Rotor Inertia Check (DRIC): As the rotor accelerates,
rotor inertia is measured and the rotor energy is calculated for the
speed set by the user. If the calculated rotor energy is determined
to be excessive, the centrifuge recalculates a permitted set speed
and uses this value to avoid possible rotor damage. A diagnostic
message is displayed to indicate the change.
• An imbalance detector monitors the system during operation,
causing automatic shutdown if rotor loads are severely out of
balance.
The instrument control housing is made of aluminum and molded
structural foam. The door and structural-foam cover panels are
finished with polyurethane enamel. The control panel is covered by
a protective overlay made of coated polycarbonate.
The door is opened by stepping on a foot pedal located at the bottom
right front of the instrument. The door is hinged at the back left to
open at a 60-degree angle to the centrifuge side panels, providing
clearance during loading and unloading of the centrifuge.
In the event of a power failure, the door lock can be manually
unlocked for sample recovery (see Section 4,
The rotor chamber is made of stainless steel to resist corrosion. A
silicone rubber gasket around the chamber opening ensures sealing.
(Instrument gaskets have not been qualified as bioseals for aerosol
containment.)
