1. An automatic pipetting system for transferring liquids from dispensing vessels, into at least one receiving vessel, wherein the system comprises:
a movable pipettor configured and arranged to be movable along an x-direction, and
a control unit for controlling the movable pipettor, wherein the movable pipettor includes
a horizontal running rail oriented along the x-direction;
an arm including two beams and a base structure, wherein the arm is movably suspended on the horizontal running rail via the base structure enabling movement of said arm along the x-direction, wherein the base structure is coupled to the two beams, and the two beams are oriented parallel to one another and project horizontally in a y-direction,
a plurality of pipetting modules configured and arranged to be movable along each of the two beams in the y-direction, normal to the x-direction, and each pipetting module of the plurality of pipetting modules includes at least one hollow needle configured and arranged to be lowerable into a plurality of dispensing vessels and a plurality of receiving vessels,
the pipetting modules of the plurality of pipetting modules are configured and arranged to move independently past one another in the y-direction, and are arranged on mutually facing longitudinal sides of said two beams.
