  • Patent number: 7618812
    Abstract: A device provides a hybridization chamber for hybridizing nucleic acid samples, proteins or tissue sections on a slide, and is an essentially rectangular body movable opposite the slide. The device includes a surface, lines for supplying and/or removing media, a specimen supply line and an agitating device. The agitation device includes at least one membrane which separates a pressure chamer to be fillable with a pressure fluid via one of the lines, from at least one agitation chamber connected via an agitation line to the hybridization chamber. The lines are continuously open so the media therein can permanently flow unhindered. Four such devices can be combined into a process unit for providing a hybridization chamber. Such unit is pivotable around an axis and has a holder with four seats, which is lockable in relation to a baseplate, one device being insertable into each one of the seats.

  • Patent number: 7615370
    Abstract: The present invention relates to a system (1) having hybridization chambers (5) for hybridizing nucleic acid samples, proteins, or tissue sections immobilized on slides (27), each hybridization chamber (5) being defined as an essentially gap-shaped chamber, which is essentially fillable with a liquid, between one of these slides (27) and a cover (26), and the cover (26) being positioned in relation to the slide (27) in such a way that the hybridization chamber (5) is sealed to the surrounding air, the system (1) including a device for preventing air bubbles in the hybridization chambers (5). The system according to the present invention is distinguished in that this device for preventing air bubbles in the hybridization chambers (5) is implemented as a pressure device to build up a chamber pressure in the hybridization chambers (5), this chamber pressure lying above the normal atmospheric pressure existing in the surrounding air.

  • Patent number: 7459306
    Abstract: A device, appropriate process units and/or systems for providing a gap-shaped hybridization space to hybridize nucleic acid samples, proteins or tissue sections over a slide. Said items of device are able to move in relation to the slide and comprise an annular sealing surface to seal the hybridization space by application to a surface of the slide. Said items of device additionally comprise lines to introduce media to and remove them from the hybridization space. Said items of device furthermore comprise a specimen supply line and preferably an agitation device to move fluids in relation to the samples immobilized on the surface of the slide. The devices according to the invention are characterized in that they limit a hybridization space that features relief structures to conduct and/or block air bubbles on at least one surface of the device and the slide directed at the interior of this hybridization space.

  • Patent number: 7425311
    Abstract: A holding device for at least one object carrier, the object carrier being suitable to receive one or more organic and/or inorganic samples and comprising materials such as glass, plastic, silicon, pyrolytic graphite, and/or metal, this holding device being configured to be gripped by grippers of a robot. The holding device comprising two essentially parallel lengthwise walls and two essentially parallel transverse walls which extend substantially at right angles from the lengthwise walls. Holding devices according to preferred embodiments are constructed in a frame shape, wherein the lengthwise and transverse walls define a frame surrounding at least one opening which completely transverses the device. Holding devices according to further embodiments are constructed a plate shape, in that the region between the lengthwise walls and transverse walls is implemented as a carrying surface. All embodiments comprising gripping surfaces on the external surface profile of the lengthwise and transverse walls.
