  • Publication number: 20200360916
    Abstract: The present invention relates to a pipette device with a pipette channel which extends along a channel axis defining an axial direction and which passes through a channel component arrangement which, at a coupling longitudinal end, has a coupling configuration for the releasable coupling of a pipette tip. The coupling configuration has a locking component with a radially outwardly facing engagement surface arrangement, which is movable between a locking position more radially remote from the channel axis and an unlocking position lying radially closer to the channel axis. The coupling configuration has a sealing component separate from the locking component, and that the actuator drive has a switchable magnetic field source and a reaction component which is movable by the locally changing magnetic field thereof and which is connected to the locking actuator in such a way as to transmit movement.

  • Publication number: 20200298242
    Abstract: A pipetting device includes pipetting unit(s), a guide assembly with at least one guide rail on which the pipetting unit(s) is guided in order to be moved along a movement axis, and a linear drive assembly, by which the pipetting unit(s) can be driven in order to be moved along the movement axis. The linear drive device has a stationary stator, and the at least one pipetting unit forms a linear drive assembly rotor which can be moved along the movement axis relative to the stator. The pipetting device also has at least two rotor magnet assemblies which interact with the same common stator magnet assembly so as to generate a drive force and which are arranged at a distance from one another along a spacing axis that is orthogonal to the movement axis. The common stator magnet assembly is located between the at least two rotor magnet assemblies.

  • Patent number: 10188574
    Abstract: The invention relates to a patella gripper for a patella, comprising a retaining element (3; 53) and a contact finger apparatus (4; 54), wherein the contact finger apparatus (4; 54) is arranged on the lower face of the retaining element (3; 53), wherein the contact finger apparatus (4; 54) comprises at least two contact finger units (4.1, 4.2; 54.1), which are arranged on opposite sides of the retaining element (3; 53), and wherein the contact finger apparatus (4; 54) is designed in such a way that the patella can be moved in the cranial-caudal direction and in the medial-lateral direction by means of the contact finger units (4.1, 4.2; 54.1). The invention further relates to a device (20; 60) having such a patella gripper (1; 51).
