Patent ID: 8119080

Claim:
A liquid handling system comprising: a robot manipulator for orienting pipette or dispenser tips in an X direction and a Y direction, which runs essentially in a Z direction perpendicularly to the X and Y direction, in relation to sample containers situated in or on the system; pipette or dispenser tips, which extend essentially vertically and may be raised and lowered in the Z direction running essentially perpendicularly to the X and Y direction; drives for moving the robot manipulator; and processors for controlling the movements and actions of the robot manipulator and/or of the pipette or dispenser tips; wherein the system comprises at least two blocks situated on two arms of the robot manipulator, at least two of said pipette or dispenser tips being situated on each block and at an axial distance to one another which essentially corresponds to the grid spacing of wells of a microplate, at least one of these blocks, for an alternating interlaced orientation of all pipette or dispenser tips which are situated on the at least two blocks along a shared line, being implemented as individually movable at least in the X direction.
