    Abstract: The invention relates to a device (1) for dispensing or aspirating/dispensing liquid samples, including a pump (2) and a micro-ejection device (3), the micro-ejection device (3) having a pulse generator (4) with a chamber (5). The pulse generator (4) is used to produce pressure waves in the liquid in order to cause the samples of a liquid to be dispensed. The micro-ejection device (3) also comprises an end piece (6) and a liquid line (7) which connects the pulse generator (4) to the end piece (6) the pulse generator comprises a micro-actuator (10) which is configured to function in the same direction as that in which the pressure wave leaves the chamber (5). The inventive devices are characterised in that the chamber (5), in the area of the end facing away from the end piece (6), or the corresponding connecting element (14) has a narrowed section (16) which restricts any expansion of the pressure waves in the direction of the pump (2). The invention also relates to systems with multiple devices of this type.

    Abstract: A device for aspirating and dispensing liquid samples comprising a pump that comprises a cylindrical chamber, a piston movable in this cylindrical chamber, and a piston drive that engages the piston. The device further comprises a tip connected to the cylindrical chamber with a line, and a channel system that discharges into the cylindrical chamber for flushing or rinsing the latter. The device is characterized in that the piston entirely seals this cylindrical chamber from the channel system, if the piston is positioned in the cylindrical chamber in such a way that a free piston end comes to rest between the channel system and the line. Preferably, the cylindrical chamber is located in a cylinder block, which comprises two parts that are separated by and enclosing an intermediate channel system. The channel system most preferably is implemented as a coherent cavity. According to a first embodiment, the cylindrical chamber is implemented as a sleeve that is inserted in a boring located in a cylinder block. According to a second embodiment, the cylindrical chamber is implemented as a boring located in a cylinder block. Furthermore, the invention also concerns systems with, for example, 384 or more such devices that are arranged in an array.

    Abstract: In an aspirating and dispensing/spraying device, a holder is screwed onto a tube, connected to a liquid supply line, in such a way that it is displaceable along the tube by rotation. The tube is surrounded at a distance by a coaxial sleeve, which is solidly anchored in the holder, having a discharge opening on its front end, which is conically narrowed, whose edge surrounds the front end of the tube, which carries a outlet opening, separated by a narrow annular gap from the tube. The sleeve carries a connecting piece laterally, to which a pressurized gas supply line is connected and which discharges eccentrically into the space between the sleeve and the tube, so that pressurized gas flowing in receives angular momentum. When the gas flows out of the annular gap, it mixes intensively with the liquid coming out of the outlet opening and forms a discharge cone made of a fine, symmetrical aerosol with the liquid. This aspirating and dispensing/spraying device is simultaneously implemented as a pipette for aspirating liquids through the outlet opening of the tube's front end, said tube carrying a sensor near said outlet opening for detecting a liquid surface during pipetting.

    Abstract: An incubation cassette is disclosed for reducing liquid evaporation from wells of a microplate. A frame has a central first opening surrounded by an inner wall having dimensions designed for the placement of a microplate therein and an outer wall which extends substantially parallel to the inner wall. The outer wall adjoins the inner wall via an intermediate bottom such that a liquid reservoir is formed thereby. The liquid reservoir surrounds the first central opening. At least a portion of the incubation cassette that forms the liquid reservoir has a transparent portion. A microplate reader has a housing and a transport support which can be pulled out of the housing. The transport support has a bearing surface for placement of a microplate having a plurality of wells or such an incubation cassette, and a controller adapted to control a method for reducing liquid evaporation from wells of the microplate.

    Abstract: A system 100 and method are provided for imaging a sample in a sample holder. For providing autofocus, a 2D pattern is projected onto the sample holder 050 via an astigmatic optical element 120. Image data 172 of the sample is acquired by an image sensor 140 via magnification optics 150. A difference in sharpness of the two-dimensional pattern in the image data is measured along a first axis and a second axis. Based on the difference, a magnitude and direction of defocus of the camera subsystem is determined with respect to the sample holder. This enables the sample holder, and thereby the sample, to be brought into focus in a fast and reliable manner.
