ABSTRACT:
A pipetting device contains a pipetting needle connected to metering device for transferring a volume of liquid from a primary vessel to a secondary vessel. Primary vessel and secondary vessels are disposed on the same or different vessel carrier units, and each vessel has a clearly defined position relative to the vessel carrier unit. Additionally, a device is provided for controlling conveyance of the pipetting needle in three directions. The controlling device controls the metering device and the conveyance device. The pipetting device independently determines coordinates of the pipetting positions for each vessel carrier unit. For each vessel carrier unit at least one reference member, which is part of the vessel carrying unit or is directly and permanently connected thereto, may be provided. These vessel carrier units have flat surfaces which are accessible to sensing the pipetting needle. The control device is capable of moving the pipetting needle to each of the surfaces of the reference member, to determine a reference point. Contact can also be determined between the pipetting needle and each of the surfaces of the reference member. Each of these surfaces determines a reference point.
