Abstract
A laboratory device, in particular for shaking and/or mixing substances, comprises a base unit, that comprises a drive apparatus, and a pivot unit, that is pivotably connected to the base unit by means of a bearing element about axes oriented perpendicular to a central axis of the base unit. The drive apparatus comprises an arrangement of magnetic elements at an inner side of a roll-off surface of the base unit and a control apparatus that is configured to control the arrangement of magnetic elements for generating a peripheral magnetic field along a closed path at an outer side of the roll-off surface to drive the roll-off section of the pivot unit by means of magnetic attraction and/or repulsion to make a rolling-off along said path.
Claims15
A laboratory device, comprising:
- a base unit and a pivot unit that is pivotably connected to the base unit by means of a bearing element about axes oriented perpendicular to a central axis of the base unit, wherein the base unit comprises a drive apparatus to drive the pivot unit to make a tumbling movement about the central axis,
- wherein the drive apparatus comprises an arrangement of magnetic elements at an inner side of a roll-off surface of the base unit and a control apparatus;
- and
- wherein the pivot unit has a peripheral roll-off section, with the control apparatus being configured to control the arrangement of magnetic elements for generating a magnetic field running around along a closed path at an outer side of the roll-of surface to drive the roll-off section of the pivot unit by at least one of magnetically attracting and magnetically repulsing the roll-off section of the pivot unit to make the roll-off section of the pivot unit roll off along said path at the outer side of the roll-off surface of the base unit.
