ABSTRACT:
An improved automated pipetting system for programmingly pipetting predetermined quantities of liquid between preselected groups of test tubes, vials or wells arranged on a horizontal table. A substantially rigid overhead frame mounted over the table on which the test tube arrays or the like are arranged. A pair of parallel X-axis guide shafts mounted in the rigid frame. A pair of helical screws rotatably mounted in the frame parallel to the pair of X-axis guide shafts. Each helical screw is driven by a stepper motor coaxially connected thereto. A pair of X-axis roller sections are movably mounted on the pair of X-axis guide shafts and support a Z-axis probe mechanism via a pair of Y-axis guide shafts and a parallel Y-axis helical screw. A stepper motor is drivingly and coaxially connected to the Y-axis screw for moving the Z-axis probe mechanism along the Y-axis guide shafts. The Z-axis probe mechanism is movably mounted on the pair of Y-axis guide shafts. The Z-axis probe mechanism is also connected to at least one stepper motor for moving a corresponding probe along the Z-axis. The Z-axis probe mechanism may include a plurality of probes, each one of which is drivingly connected to a stepper motor. The movement of the stepper motors are controlled by a computer in accordance with a computer program.
