Overview of Functions

A dDrive with a DispenSix six-port burette functions as liquid handler.
The piston in the burette is connected to the piston rod of the dDrive. The piston rod and therefore the piston are moved by the spindle motor in the dDrive. The spindle motor has a resolution of 120000 steps. This allows for accurate and aspiration and dosing of liquids.
The gear on the dDrive rotates the burette and therefore controls which port is open for aspiration or dispensing.
The main instrument controls the actions of the dDrive.

Read the User Manual of the burette for more information on the function of the burette.
Read the Reference Manual of the main instrument for more information on the programming of the aspiration and dispensing.
