Patent ID: 7575937

Claim:
A device for situating pipette tips in a system for manipulating liquid samples, this device comprising: A robot manipulator for orienting pipette or dispenser tips in an X direction and in 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 movement and actions of the robot manipulator and/or of the pipette or dispenser tips; Wherein the device comprised at least two blocks situated on an arm of the robot manipulator, on each of which at least two of said pipette or dispenser tips are situated 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 the alternating interlaced orientation of the pipette or dispenser tips of the two blocks along a shared line—being implemented as individually movable in the X direction and in the Y direction.
