1. An automatic apparatus suitable for the withdrawal of portions of biological material from a parent test tube, mobile in a conveyor of a test tube transport plant by means of a transport device of single test tubes, to be loaded in one or more children test tubes which have been countermarked beforehand, which comprises:
a work bench which provides a first lane provided with a stop point for queued children test tubes, a second lane provided with a stop point for queued parent test tubes, a return third lane for accommodating parent test tubes and children test tubes filled with aliquots or portions of biological material received from the parent test tube, said parent test tube being previously released from the stop point to reach a work point on the second lane, followed by a predefined number of children test tubes which were previously released and queued after the parent test tube, behind the work point passing from the first lane to the second lane through a diversion, the actual presence of the expected number of children test tubes queued after the parent test tube in the work point being controlled by the presence of sensors appropriately positioned at the second lane;
a device suitable for the withdrawal and distribution of portions of biological material from the parent test tube to the respective children test tubes queued to the parent test tube at the work point of the work bench;
a device suitable for presenting pipettes in an appropriate position at each new work cycle, and suitable for the withdrawal of portions of biological materials and their distribution in children test tubes; and
a control unit suitable to coordinate and check the devices involved in the work cycle of the described device.
2. The apparatus according to claim 1, wherein a recruitment device for the child test tubes is interfaced with the work bench, said recruitment device comprising a test tube revolving device providing an inclined revolving dish including a lodging for a test tube constituted of retractable pegs and a fixed peg, a sensor suitable to detect the position of the test tube on the revolving dish and means suitable to operate the revolving dish in case the test tube does not face the prescribed side for the subsequent drop into a test tube marking device.
3. The apparatus according to claim 1, wherein the device suitable for presenting the pipettes comprises a comb suitable to raise, one by one, horizontal pipettes towards two guides spaced between them in such a way to cause the straightening of the pipette, and pneumatic pushing means suitable to raise the pipette towards a pipette loading position.
