  • Publication number: 20210078010
    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.
