摘要:
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.
摘要:
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).

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).

摘要:
Devices (1) and methods are disclosed for situating pipette or dispenser tips (2) in a system (3) for manipulating liquid samples (4). A device (1) according to the present invention comprises: a robot manipulator (5) for orienting pipette or dispenser tips (2) in relation to sample containers (6) situated in or on the system (3); pipette or dispenser tips (2); drives for moving the robot manipulator (5); and processors for controlling the movements and actions of the robot manipulator (5) and/or of the pipette or dispenser tips (2). The device (1) according to the present invention is characterized in that it comprises at least two blocks (8, 9) situated on an arm (7) of the robot manipulator (5), on each of which at least two pipette or dispenser tips (2) are situated at an axial distance (10) to one another. The axial distance (10) essentially corresponds to the grid spacing of wells (19) of a microplate (18). At least one of these blocks (8,−9)—for the alternating interlaced orientation of the pipette or dispenser tips (2) of the two blocks (8,−9) along a shared line (12)—is implemented as individually movable in the X direction and in the Y direction. The method according to the present invention allows the time-saving pipetting over of liquid samples (4) between diverse sample containers, e.g., between sample tubes and microplates (18) having 24, 96, 384, or 1536 wells.
摘要:
A gripper housing (16) of a gripper (14) is suspended from two rotatable sliding bars the ends of which are connected to sleeves (50, 51). 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). By rotation of the first sliding bar, the sliders (39a, 39b) with the gripping fingers (40a, 40b) can be displaced relative to each other via the gripper wheel (33), gripper pinion (34), gripper bolt (37), and gear wheels (38a, 38b), while by rotation of the second sliding bar the tong housing (17) can be rotated via the turning wheel (47) and the turning pinion (48).
摘要:
A device for transferring and characterizing objects positions the object on a horizontal work field. The device includes at least one rail extending parallel to the X direction and a displacement unit, movable back and forth in the X direction, having a motorized gripping mechanism for grasping an object. A processor for controlling movements of the displacement unit and actions of the gripping mechanism is distinguished in that the displacement unit includes a carrying device, movable together therewith along the rail, for transferring objects in the X direction. The carrying device is a plate for carrying objects moved onto this carrying plate using the gripping mechanism. According to a method of the invention, objects are moved onto the plate of the carrying device, transferred in the X direction, and deposited again at a second position.

摘要:
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.
