Abstract

A device (1) for transporting or examining liquids in a system (3) for working with liquid specimens (4) that comprises an essentially horizontal working field (5) extending in an X orientation and in a Y orientation at right angles to the latter. The device (1) comprises at least one functional element (2) with at least one functional end (22), whereby said functional elements (2) are aligned essentially at right angles to the working field (5) in a Z orientation. The device (1) also comprises at least one tilting unit (8) for tiltable retention of the at least one functional element (2). An inventive device (1) is characterized in that the tilting unit (8) comprises actuators (10) for individual pointing of the functional ends (22) of the functional elements (2) in relation to a Z axis (11) perpendicular to the working field (5), and a control unit (17) to electrically drive the actuators (10), whereby each of the functional elements (2) can be tilted individually and independently of the X and Y orientation of the working field (5). The device (1) is preferably attached to a robot arm (6) intended to move the functional element (2) in at least one section (7) of the working field (5) and at least on the Z axis. In this case the control unit (17) is intended to coordinate control of the movement of the robot arm (6) and the change in position of the functional ends (22) of the functional elements (2) in relation to a Z axis (11) perpendicular to the working field (5).
