Entering Acceleration and Deceleration Rates

The centrifuge provides a choice of three acceleration rates and four deceleration rates to protect
the gradient and sample-to-gradient interface.
the centrifuge accelerates and decelerates at maximum rates.
The default setting for both acceleration and deceleration is maximum (
the JS-24.38 and the JS-24.15. Maximum acceleration and deceleration are not available for these
rotors.

TIMED
Description
Full torque is used from 0 RPM until set speed is reached.
Approximately 2 minutes from 0 to 500 pm. (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.
Acceleration time from 0 to 500 RPM can be set from 1 to 10 minutes. 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 time
can be set from 1 to 10 minutes.
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.
