8 Acceleration and Deceleration Rates

 

The user has 9 kinds of acceleration and deceleration rate to satisfy the sample 

separation. Acceleration and deceleration can be changed in the rate from 0rpm to 

1000rpm. Figure 8.1 is shown as follows: 

 

 

                     

 

Figure 8.1 The schematic diagram of acceleration and deceleration curves 

Advice for Selection of Acceleration and deceleration Rates 

 

To collect precipitate, it is recommended to set acceleration and deceleration grade at 

9 to efficiently separate it. 

 

To avoid a disturbance during deceleration process, it is recommended to select the 

grade at 6, 5, 4 or 3. 

 

To  separate  invisible  samples,  such  as  DNA  in  microtubes,  it  is  recommended  to 

choose 7 or 8 grade of acceleration and deceleration rate.
