摘要： The present invention defines a positioning assembly including a base part (110) and a holder part (120) for holding a device, whereby the assembly further includes a motor (160) for driving a displacement mechanism (150) mounted to the base part. The base part and the holder part are arranged parallel to each other and are connected via a displaceable slide link (140), which is configured to slide on a first guide rail (111) provided on the base part and on a second guide rail (122) provided on the holder part, whereby each guide rail extends in longitudinal direction (z). The slide link (140) is coupled to the displacement mechanism (150), which causes displacement of the slide link relative to the base part in longitudinal direction. Furthermore, the holder part (120) is moveably coupled to the base part (110) via a coupling arrangement which has a first element (115) provided on the base part, a second element (125) provided on the holder part and a third element provided on the slide link (140). The first, second and third elements of the coupling arrangement are configured to engage with each other such that linear displacement of the slide link (140) relative to the base part (110) in one direction causes linear displacement of the holder part (120) relative to the slide link in the same linear direction.

摘要： An imaging system and method are provided in which a well of a microplate 050 is imaged by a camera 110 comprising magnification optics 112. The camera is controlled to acquire a series of images of the well with different exposures. The series of images comprise a base image with a base exposure and at least one further image with a larger exposure than the base exposure. The series of images are then merged into an output image which comprises in a center region of the well image content from the base image and at a peripheral region of the well image content from the at least one further image. Advantageously, the output image may allow for better assaying or analysis of the samples in the well than any of the individual images.

摘要： A transport tool for transporting a laboratory article using a pipette of a pipetting system and having a plug-in sleeve at a top end, an article holder at a bottom end, and a connecting part which connects the plug-in sleeve to the article holder. The plug-in sleeve has a side sleeve wall and a bottom which surround an interior space of the plug-in sleeve having a cylindrical and conically tapering shape. The plug-in sleeve further has an upward-facing opening for receiving an end of a pipette of an automated pipetting system. The connecting part has a top surface which defines the bottom of the plug-in sleeve, is positioned between the interior space of the plug-in sleeve and the article holder. The article holder has a holding plate which is flat and faces downward away from the plug-in sleeve, and further has a flatly acting magnet on the holding plate.

摘要： Aspiration of a pipette arrangement is initiated. A sensor arrangement senses a least one prevailing first parameter that is dependent from the effect in the pipette arrangement during initiating and upholding the suctioning action. This at least one parameter is analyzed in an analyzing stage. From a result of this analysis and in a determining stage at least one test criterium TC for at least one further parameter as sensed by the sensor arrangement is determined. In a checking stage there is checked whether this further parameter fulfills the at least one test criterium.

摘要： Microplate reader has measuring space, action source, measuring device for biological structure signals of microplate wells, transport support for positioning wells in relation to an optical axis of the device and controller for the action source, the measuring device and the transport support. An incubation apparatus with a frame accommodates a microplate with wells having bottoms for reducing liquid evaporation. The frame has a first opening surrounded by an inner wall for the microplate and an outer wall parallel to the inner wall and connected thereto by an intermediate bottom so that a channel is formed and the intermediate bottom for accommodating a liquid adjusted to the content of the microplate wells. The incubation apparatus has a support surface with a second opening for a microplate and, as a result, at least a portion of the well bottoms is freely accessible by the second opening.

摘要： A disposable cartridge used in a digital microfluidics system has a bottom layer with first hydrophobic surface, a rigid cover plate with second hydrophobic surface, and a gap there-between. The bottom layer is a flexible film on an uppermost surface of a cartridge accommodation site of a system, attracted to and spread over the uppermost surface by an underpressure. A lower surface of the plate and the flexible bottom layer are sealed to each other. The assembled cartridge is removed from the cartridge accommodation site in one piece and potentially includes samples and processing fluids. The system has a base unit and a cartridge accommodation site with an electrode array of individual electrodes and a central control unit for controlling selection of individual electrodes and for providing these electrodes with individual voltage pulses for manipulating liquid droplets within the gap by electrowetting.
