Entering Acceleration and Deceleration Times

The centrifuge provides a choice of two acceleration rates (one for ARIES rotors) and four
deceleration rates (three for ARIES rotors) to protect the gradient and sample-to-gradient interface.
Table 2.1 describes these rates. If no rate is selected, the centrifuge automatically accelerates and
decelerates at maximum rate.

Description
Full torque is used from 0 RPM until set speed is reached.
Approximately 2 minutes from 0 to 500 RPM. (Time depends on the mass of the
rotor in use; larger rotors take longer.) Above 500 RPM, full torque is used until
set speed is reached.
Full brake from set speed to near 0 RPM. Reduced brake is used during the last
few RPM until 0 is reached to minimize sample disturbance.
Reduced torque from set speed to 500 RPM, then approximately 2 minutes from
500 to 0 RPM. Deceleration to 500 RPM takes about twice as long as with
maximum deceleration. (The exact time depends on the mass of the rotor in
use; larger rotors take longer.)
Full brake from set speed to 500 RPM. From 500 to 0 RPM, deceleration can take
from 1 to 10 minutes (time is set by the user).
No brake is used. Rotor coasts from set speed to 0 RPM. Can take up to 1 hour,
depending on the mass of the rotor in use and the set speed.
