Workflow support for zonal centrifugation

A centrifuge system for performing zonal centrifugation operation, the centrifuge system comprising a centrifuge device comprising:

• a zonal rotor having a cavity, the zonal rotor configured to receive a sample onto a density gradient contained in the cavity;
• a display device adapted to display a user interface;
• and
• a processing device adapted to:
• control a rotation of the zonal rotor to operate the zonal rotor in a loading mode where the sample is loaded onto the density gradient, a running mode, and an unloading mode where a separated sample is unloaded from the zonal rotor, wherein the control of the zonal rotor causes the zonal rotor to spin in each of the loading mode, the running mode, and the unloading mode;
• generate the user interface with the display device, the user interface displaying a loading step-indicator when the zonal operator is operating in the loading mode, a running step-indicator when the zonal rotor is operating in the running mode, and an unloading-step indicator when the zonal rotor is operating in the unloading mode;
• and
• receive an input from a user indicating the sample is loaded.
