    Each design shows a small laboratory vortex mixer visually characterized by a rectangular frame main body that features rounded edges; the frame main body tapers downward to the right after about the first half when viewed from the front, creating a sort of ramp downward toward the front that ends about 2 cm before the frame body end; within the ramp, there is a rectangular display that contains the electronic user interface of the device; in the first third of the top of the frame, which is on the left when viewed from the front, there is a rectangular plate about 1 cm thick with a hole in the center; around the hole, there are numerous small round protrusions, evenly spaced; the design of the device is characterized by a two-tone design, where the upper part of the main body of the frame has a light color and contrasts with the lower, darker part of the main body of the frame; under the main body of the frame there are four round elevations that serve as feet under the main body.

    Abstract: The invention relates to a plunger rod (10) for a liquid transfer device (100), wherein the plunger rod (10) is of two- or multipart construction. The plunger rod (10) has a first plunger rod component (12), which is in operative connection with an actuating device (110) of the liquid transfer device (100), and a second plunger rod component (14). The plunger rod (10) further comprises a sealing seat (16) for receiving a sealing element (18) for the plunger rod (10), wherein a parting line (20) between the first plunger rod component (12) and the second plunger rod component (14) is configured such that the sealing seat (16) is free of parting line flash (22).
    The invention further relates to a method for producing such a plunger rod (10) and a liquid transfer device (100), in particular a pipette (102, 104, 106) and/or a multichannel bottom part (108) for a pipette (102, 104), with such a plunger rod (10).

    Abstract: The disclosure relates to laboratory equipment with flammable refrigerant and connected to at least two different electrical potentials for supplying the equipment with electrical energy. An electrical switch arrangement has first and second switches for electrical separation from, respectively, the first and second potentials. A sequence controller switches on the first switch and thereafter the second switch. A monitoring device is connected via a first contact on the equipment side to the first switch and via a second contact on the mains side to an electrical potential other than the first electrical potential for detecting a switched-on state of the first switch and signaling the detection to the sequence controller. When the monitoring device signals a switched-on state, the sequence controller blocks operation of the equipment as a function of the signaled switched-on state and whether the first switch is expected to be switched on or switched off.

    Abstract: A method for controlling functional elements and a device for use in bioprocess engineering or medical technology is disclosed. The method includes providing a first functional element, which has a memory, in which items of element information having specifications about the type and the function of the functional element are stored, and providing a second functional element. The method includes connecting the first and the second functional element to a control unit, reading the items of element information out of the first functional element and carrying out a check of the read-out items of element information from the second functional element or using items of information which are stored in the control unit. The first functional element is controlled by the control unit in dependence on the check or in dependence on the items of element information.
