  • Publication number: 20200282390
    Abstract: The present invention relates to a pipetting apparatus for aspirating and dispensing metered liquids, encompassing: at least one guidance tube (30) extending along a cylinder axis (Z), the cylinder axis (Z) defining: an axial direction proceeding along its direction of extent; a radial direction proceeding orthogonally thereto; and a circumferential direction extending therearound; a piston (10) received in the guidance tube (30) axially movably relative thereto; a coupling configuration embodied for temporary or permanent coupling of a pipetting tip; and a drive apparatus (32) for driving the piston (10) to move axially relative to the guidance tube (30), the guidance tube (30) comprising a coupling-side longitudinal end (48) that is located closer to the coupling configuration; and comprising a servicing-side longitudinal end (50) that is located oppositely from the coupling-side longitudinal end (48) and is located farther from the coupling configuration; the piston (10) encompassing at least one pe

  • Publication number: 20190247844
    Abstract: A permanent-magnet piston subassembly (10) for a pipetting apparatus, the piston subassembly (10) extending along a piston axis (K) and comprising a plurality of permanent-magnet arrangements (14a to 14m) that are arranged one behind another along the piston axis (K) with alternatingly opposite polarization directions in such a way that for each two permanent-magnet arrangements (14i, 14j) directly successive along the piston axis, it is the case that magnetic poles located closest to one another along the piston axis (K), of different successive permanent-magnetic arrangements (14a to 14m), are like poles, is characterized in that the piston subassembly (10) encompasses a sheath tube (12), extending along the piston axis (K) constituting a tube axis (H), in which the plurality of permanent-magnet arrangements (14a to 14m) are received.
