  • 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: 20200076275
    Abstract: There is provided a method for contactless determination of the position of a driven moving portion (4) of an electric motor (2) by means of a plurality of magnetic field sensors (8), wherein the moving portion is movably arranged with respect to a stator (6) and has a plurality of permanent magnets (40) which generate a moving-portion magnetic field having a plurality of periodically spaced apart maxima, and wherein the plurality of magnetic field sensors are arranged along a movement path (43) of the moving portion.

  • Publication number: 20190358626
    Abstract: A pipetting apparatus and method for pulsed dispensing of small metered-liquid doses of no more than 1 ?l. The apparatus includes a pipetting conduit at least partly filled with working gas, a pressure-modifying apparatus for modifying the pressure of the working gas, and a control apparatus for applying control to the pressure-modifying apparatus. The control apparatus can control the pressure-modifying apparatus so as to generate in the pipetting conduit, with respect to a reference holding pressure in the pipetting conduit which is necessary for immovable holding of the metered-liquid quantity, an overpressure pulse having a pulse duration of no more than 40 ms.
