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: The invention relates to a laboratory device, in particular to a magnetic stirrer, having a heating unit for heating a medium, in particular a liquid, in a container, and having a regulating unit that is configured to regulate the temperature of the medium, of the heating unit and/or of the container by controlling the heating power of the heating unit, wherein a weight determination unit is provided to determine the weight of the medium, and wherein the regulation of the temperature takes place in dependence on the weight determined.

Abstract: A rotary evaporator is provided. The rotary evaporator includes a rotary drive and a piston support (11) for an evaporator piston which can be coupled to the rotary drive. The piston support (11) comprises two transverse carriers (19, 21) for supporting the evaporator piston at two support regions spaced apart from one another and a longitudinal guide (25) having a guide element (27), on which longitudinal guide the two transverse carriers (19, 21) are moveably arranged in order to vary the mutual spacing of the two transverse carriers (19, 21). The guide element (27) is displaceably guided in the longitudinal direction (23) in order to displace the evaporator piston between a coupling position with the rotary drive and a position spaced back from the rotary drive.

Abstract: A rotary evaporator comprises a device (10) for securing a ground connection, comprising a ground sleeve and a ground core, between an evaporator piston and a vapor leadthrough. The securing device has a receiving opening (17) for that end of the evaporator piston provided with the ground sleeve, and a securing element (13) which can be moved between a retaining position and a release position and which has a retaining section (31) that, in the retaining position, projects into the receiving opening (17) and that, in the release position, is at least partially retracted from the receiving opening (17), so as to secure or release, as desired, that end of the evaporator piston provided with the ground sleeve.

Abstract: The invention relates to a lab stirrer, in particular to an overhead stirrer, having a stirring unit and having a stirring member which can be rotatingly driven by the stirring unit and is provided for immersion into a medium to be stirred, with the stirring member being provided with at least one measurement sensor for the measurement of measurement data of a measurement parameter of the medium. The stirring member is provided with a measurement circuit which includes a data transmission device to transmit the measurement data in a contactless manner to a receiver unit not rotating with the stirring member.
