Abstract: A laboratory device includes an outer surface section. The laboratory device further includes a display apparatus that displays a respective temperature state of the outer surface section. In addition, the laboratory device utilizes at least also heat of the outer surface section for the energy supply of the display apparatus.

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.

Abstract: A lab stirrer comprises a housing, a stirring shaft rotatably supported about an axis in the housing and a drive to drive the stirring shaft to make a rotary movement about the axis. A blocking device is provided to block the stirring shaft against a rotation about the shaft axis.
