  • Patent number: 10803266
    Abstract: An identification device for identifying identifiers on and/or features of laboratory objects and/or of samples located therein in conjunction with automated laboratory systems or facilities, for example, medical, chemical, or pharmaceutical analysis devices. Barcodes on sample containers, for example, sample tubes, reagent tubs, or microplates are used, for example, as identifiers. An optical recording unit and a mirror are used, the spacing is variable for the detection of laboratory objects, each at different distances, from a recording distance by the optical recording unit is within a depth of field of the optical recording unit. The mirror is used for imaging the laboratory object to be detected on the optical axis. The identification device is substantially simplified, more reliable, and more cost-effective in comparison to known devices that use a zoom lens together with an autofocus unit.

  • Patent number: 8119080
    Abstract: A liquid handling system has a robot manipulator for orienting pipette or dispenser tips in relation to sample containers situated in or on the system, pipette or dispenser tips, drives for moving the robot manipulator, and processors for controlling the movements and actions of the robot manipulator and/or of the pipette or dispenser tips. The system also includes at least two blocks situated on two arms of the robot manipulator, at least two of the pipette or dispenser tips being situated on each block and at an axial distance to one another. The axial distance essentially corresponds to the grid spacing of wells of a microplate. At least one of these blocks, for the alternating interlaced orientation of the pipette or dispenser tips of at least two blocks along a shared line, are individually movable at least in the X direction. A method allows the time-saving pipetting over of liquid samples between diverse sample containers, e.g., between sample tubes and microplates having 24, 96, 384, or 1536 wells.

  • Patent number: 6705962
    Abstract: A drive unit of a carriage has a drive wheel and a deflector, offset parallel to a racks both of which are implemented as gearwheels, around which a closed elastic toothed belt with teeth on both sides is guided, whose inner teeth engage with the wheels described and whose outer teeth engage with the rack. A pressure block relocatable relative to the rack is positioned between the wheels, which exercises an elastic force on the part of the toothed belt facing the rack by means of a pressure surface under the influence of the part facing away from the rack, which presses the first part mentioned against the rack. In this way, a snug engagement with the rack and low-noise and uniform movement of the carriage are always ensured. A pressure wheel implemented as a pinion and engaging with the inner teeth of the toothed belt can also be used instead of the pressure block.

  • Patent number: 6458324
    Abstract: A workstation has a transfer device with a gripper which is suitable for gripping sample tubes by a gripper clamp and for moving them from a sample tube rack to a sample tube bucket, for example for centrifuging. The transfer device has a receiving device (23) which can be gripped on a cylindrical upper handling part (25) by the gripper and removed from a holder (24) in which it has been placed in a defined position. It has an intermediate part (33) with, on its lower end, four hooks (37) which are arranged at the apices of a rectangle and can engage eyes in the sample tube buckets. After use, the receiving device (23) is replaced in the holder (24).

  • Patent number: 6455002
    Abstract: A workstation has a feed device (1) for sample tube racks (7), comprising a balance (17) in which the weight of individual sample tubes (6) is determined by a procedure in which the sample tube holder (7) is weighed in each case before and after removal of each sample tube (6) and the difference between the weights is determined. Removal is effected in each case by means of a gripper (23) of a transfer device (3) which then distributes the sample tubes (6) over sample tube buckets (22) in such a way that said buckets form pairs having approximately the same weights. With the aid of a receiving device (27) which is gripped by the gripper (23) and removed from a holder, the sample tube buckets (22) are picked up and introduced into a centrifuge (2). They are removed again after centrifuging and, after the receiving device (27) has been deposited in the holder, the individual sample tubes (6) are removed from the sample tube buckets (22) by the gripper and deposited on carriers (5) of a conveying device (4).

One of these is provided with a turning wheel (47) meshing with a turning pinion (48) nonrotatably connected with a tong housing (17) rotatably supported on the gripper housing (16). The other is provided with a gripper wheel (33) meshing with a gripper pinion (34) which is connected with gear wheels (38a, 38b) in the tong housing (17) via a gripper bolt (37) passing coaxially through the turning pinion (48). The gear wheels (38a, 38b) mesh with gear racks (52b) on sliders (39a, 39b) which are displaceably supported in the tong housing (17) and have gripping fingers (40a, 40b).
