Entering Acceleration and Deceleration Rates

The ultracentrifuge provides ten acceleration rates and eleven deceleration rates to protect the
gradient and sample-to-gradient interface.
numbers on the touchscreen interface. Acceleration time is the time it takes a rotor to reach
5000 RPM from rest. At 5000 RPM, maximum acceleration takes over until the rotor reaches set
speed. Deceleration time is the time it takes a rotor to decelerate from 5000 to rest. From set speed
to 5000, the rotor decelerates with full dynamic braking.
