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.

Motion systems for loading tips

A pipetting device is disclosed. The pipetting device can include a piston with a stepped profile. The piston can be inserted into a barrel and can have at least two seal elements. The pipetting device can operate in a low volume dispense mode and a high volume dispense mode. The pipetting device can allow for high volumes of liquids to be transferred and also provide for the ability to transfer low volumes of liquids with high precision and accuracy without the need for two or more separate pipettor devices.
