摘要： A method for aspirating a first liquid medium from a sample container with a laboratory automation device, wherein the first liquid medium is above a second liquid medium, which has a higher density and/or viscosity as the first liquid medium comprises: detecting a surface position of a surface of the first liquid medium; calculating an estimated interface position of an interface between the first liquid medium and the second liquid medium from the surface position and calculating a safety position between the surface position and the estimated interface position by adding a safety offset to the estimated interface position; and lowering a pipette of the laboratory automation device into the sample container and aspirating the first liquid medium from the sample container with the pipette by generating an underpressure in the pipette until a pipette tip of the pipette reaches the safety position.

摘要： A centrifugal processing unit for directing the movement of substances within a sample processing cartridge, the centrifugal processing unit having a rotor at least one accommodation for receiving the sample processing cartridge, and a rotor drive for rotating the at least one rotor about a respective rotor axis to create the centrifugal force. The centrifugal processing unit has a blocking element allowing the free pivoting motion of the at least one accommodation in a release position when the rotor is rotated in a first direction and preventing the free pivoting motion in a blocking position, when the rotor is rotated in the opposite direction.

摘要： Some embodiments are directed to image registration. A rotation angle is determined and subsequently a translation vector. The rotation angle and translation vector together defining an alignment transformation between a first image and a second image. Determining the rotation angle may include iterating over multiple potential rotation angles, and determining alignment.

摘要： A liquid droplet manipulation system has a substrate with at least one electrode array and a central control unit for controlling selection of individual electrodes of the electrode array and for providing the electrodes with individual voltage pulses for manipulating liquid droplets by electrowetting. A working film is placed on top of the electrodes for manipulating samples in liquid droplets with the electrode array. At least one selected individual electrode of the electrode array is configured to be penetrated by light of an optical detection system for the optical inspection or analysis of samples in liquid droplets that are located on the working film. Also disclosed is working film that is to be placed on the electrode array and a cartridge that includes such a working film for manipulating samples in liquid droplets.

摘要： A method for aspirating a first liquid medium of two liquid media of different density from a sample container comprises: lowering a pipette of the laboratory automation device into the sample container until a pipette tip of the pipette has passed a lowering distance from the surface of the first liquid medium in the sample container, wherein the lowering distance is chosen, such that the pipette tip passes at least an aspiration volume in the sample container; aspirating liquid from the sample container during the lowering of the pipette by generating an underpressure in the pipette, wherein the first liquid medium is aspirated, and after the interface and the pipette tip pass each other, the second liquid medium of the two liquid media is aspirated; measuring a pressure in the pipette during the lowering of the pipette and detecting a position of the interface, when a slope of the pressure changes; when the lowering distance has been passed and no interface is detected, aspirating the aspiration volume from the first liquid medium and dispensing the aspiration volume of the first liquid medium into a further sample container.

摘要： The invention relates to an arrangement of a gripper finger and a clamp for use in an automated parallel gripper comprising first and second gripper fingers that are moveable in a direction of translation (y), whereby the clamp is connected to the gripper finger at an underside thereof, so as to be rotational about a vertical axis of rotation (135). The clamp has a front face with a contact surface for engagement with a lateral edge of an item to be gripped and has a default orientation in which the front face is parallel to a lateral direction (x) that is perpendicular to the direction of translation (y) and to the vertical rotation axis (135). The arrangement is additionally provided with a self-alignment feature which comprises first and second biasing mechanisms arranged at either side of the rotation axis (135) in lateral direction (x). Each biasing mechanism has a first part (151, 152) connected to the finger and a second part (131, 132) connected to the clamp and is configured to exert a centering force that urges the first and second parts of each biasing mechanism into alignment with each other. When the clamp is in the default orientation, each biasing mechanism is preloaded to exert an equal moment load on the clamp in the direction of translation (y).
