Pipettor system

A system comprising:

• a pipetting chamber;
• a set of pipettor cartridges docked in the pipetting chamber;
• a carrier configured to transport in the X, Y and Z directions each pipettor cartridge of the set of pipettor cartridges to a pipetting location within the pipetting chamber;
• a tray dock movably mounted within the pipetting chamber;
• wherein the tray dock is shufflable within the pipetting chamber relative to the pipetting location, the tray dock including more than one tray dock sections each being separate and distinct from each other, and each of the more than one tray dock sections being shuffled with respect to each other relative to the pipetting location so as to swap different pipetting trays or other liquid trays at the pipetting location;
• and
• a robotic arm connected to the pipetting chamber, configured to move the different pipetting trays, and the other liquid trays, to and from the pipetting chamber, wherein the robotic arm is configured to operably communicate with at least one supply system to transfer the different pipetting trays and other liquid trays between the at least one supply system and pipetting chamber.
