Abstract: A laboratory instrument for fixing an object carrier, the instrument including a main component for receiving an object carrier, a positioning fixture for application to a first edge region of the object carrier, a second positioning fixture for application to a second edge region of the object carrier, a fixing mechanism for fixing the object carrier on the main component between the first positioning fixture and the second positioning fixture by moving at least the first positioning fixture, and an actuating device for actuating the fixing mechanism for transposing at least the first positioning fixture between an operational state and an operational state which releases the object carrier, wherein the fixing mechanism includes at least one guide body which can be guided in at least one guide recess.

Abstract: A laboratory instrument for mixing a medium in an object carrier, wherein the laboratory instrument includes a support body, a main component for receiving the object carrier which is disposed on the support body and is movable with respect to the support body for mixing, and a mixing drive mechanism disposed on the support body, with a drive device, a first eccentric and a second eccentric, which can be driven by means of the drive device and which are configured in order to transmit a driving force produced by the drive device to the main component in order to mix the medium in the object carrier, wherein the first eccentric and the second eccentric are disposed on a peripheral edge of the support body and outside a central region of the support body.

Abstract: The invention relates to an apparatus (100) for positioning a sample carrier plate, wherein the apparatus (100) comprises a main body (102) for receiving the sample carrier plate, positioning stops (106, 108) which are disposed in opposing first corner regions of the main body and are prestressed for clamping the sample carrier plate and mounted displaceably, an actuating device (114) which is disposed in a second corner region of the main body and is equipped such that by actuating the actuating device (114) the positioning stops (106, 108) can be transferred between an operating state engaging the sample carrier plate and an operating state releasing the sample carrier plate, and comprises a force transmitting element (118) which is equipped to transmit an actuating force from the actuating device to the positioning stops.

Abstract: An apparatus for positioning a functional device, wherein the apparatus has a main body, a carrier element that can be disposed on the main body to receive the functional device, positioning stops, which are mounted displaceably to clamp the functional device, an actuating device which is adapted such that, by actuating the actuating device, the positioning stops can be transferred between an operating state engaging the functional device and an operating state releasing the functional device, and a force transmitting element which is adapted to transmit an actuating force from the actuating device to the positioning stops, wherein the actuating device and the force transmitting element are coupled in such a manner that, in the operating state engaging the functional device, the force transmitting element transmits a functional device force of the functional device to the actuating device in such a manner that the actuating device remains in a rest position with respect to the carrier element, in spite of the
