Abstract: Embodiments of lab automation workstations are disclosed in which the pod that performs pipetting operations is integrated with pipette tip-loading functionality. To generate the necessary tip-loading force, a dual drive system is used that is symmetric about the Y-axis to allow for offset or partial tip box loads by dynamically centering the drive force (e.g., the tip-loading force) over the reaction load. This minimizes the need for oversized linear motion components while still allowing for the generation of high tip-loading forces needed to properly load a large number of pipette tips simultaneously.
