Abstract: A gripper having a mechanical coupling that can be connected to a pipetting tube, at least one fluid channel extends from the coupling and a negative pressure can be transmitted, the gripper having at least one suction cup that is connected to the coupling through the at least one fluid channel as a result of which the negative pressure can be transmitted from the coupling to the at least one suction cup, and the at least one suction cup in the intended use position of the gripper is aligned such that a rim of a suction cup of the at least one suction cup is aligned in a substantially vertical plane.

Abstract: A device which has a deliverable sensor, a container for receiving a liquid, a container environment and a signal processing circuit, the input side of which can be connected circuitry-wise to the sensor. The device is designed to perform a capacitive liquid level measurement in normal operation using the sensor, wherein a threshold value can be predefined for the signal processing circuit for normal operation. The device has a classification module which can be connected with an input side or line connection circuitry-wise to the sensor, is designed to make a capacitive measurement of the liquid in the container using the sensor and can be connected circuitry-wise to the signal processing circuit in order to trigger the specification of a threshold value using the sensor for capacitive measurement of the liquid.

Abstract: The present invention relates to a method for determining the position of a robotic arm in an automatic liquid handling system in which a measurement probe with a first electrode is arranged on the robotic arm and, together with a second electrode formed by at least part of a working area or at least part of a container or container carrier forms a measurement capacitor that is operatively connected to a measurement unit for measuring an impedance, in particular a capacitance of the measurement capacitor. The method involves moving the measurement probe along a first path, detecting a first change in the impedance, in particular in the capacitance of the measurement capacitor at a first point on the first path, and defining at least one first reference spatial coordinate for a control unit of the robotic arm on the basis of the first point on the first path.
