摘要： This application provides a method for controlling a planar drive system, where the planar drive system comprises at least a controller, a stator module having a stator surface, and a rotor that may is positionable and movable on the stator surface. The method comprises positioning an object on a rotor in a first arrangement state of the object in a positioning step, carrying out an accelerating movement of a defined movement pattern of the rotor; and, by the accelerating movement, arranging the object positioned on the rotor in the first arrangement state in a second arrangement state relative to the rotor, in an arranging step. The application further provides a planar drive system.

摘要： The present disclosure provides a device for assisting agitation of liquid. The device includes a frame having a bottom and a sidewall forming an angle with the bottom; a first flexible film attached to the frame at a periphery portion of the first flexible film; a first magnetic field generator at the sidewall of the frame and adjacent to the periphery portion of the first flexible film; and a second magnetic field generator at the bottom of the frame, wherein the first magnetic field generator and the second magnetic field generator are configured to provide a magnetic field parallel to at least a portion of the first flexible film, and wherein a portion of the frame and the first flexible film are configured to be in contact with the solution.

摘要： Disclosed is a process photometer arrangement (10) with a photometric cuvette unit (20) comprising a cuvette body (24) defining a cuvette cavity (25) and a combined sample inlet/outlet opening (34), a photometer light inlet window (60) and a photometer light outlet window (62). The cuvette body (24) is movably supported by a cuvette body support element (88) and the cuvette unit (20) is provided with a cuvette vibration device (80) for vibrating the cuvette body (24) to thereby quickly and homogenously mix a liquid sample volume (31) within the cuvette cavity (25) without any separate mixing element within the cuvette cavity. This allows a short mixing action within a microfluidic cuvette.
