Abstract: Disclosed is a stretcher (3) that is removably connected to a transport device (1) in order to be transported. The positioning and coupling parts for securing the stretcher (3) to the therapy table (25) and the examination table are integrated into a space (32) inside the stretcher body (13), so the stretcher body (13) can be placed directly on the surface of the therapy table (25) and can be positioned thereon and secured thereto.

Abstract: The sampling apparatus for a biological reactor comprises a probe housing which is connectable to a connection port of a bioreactor. A probe located within the probe housing contains a head region having a semipermeable membrane which permits the passage or throughflow of culture filtrate, but does not allow the entrance of cells. In order to avoid clogging of the semipermeable membrane, this probe is connected with a vibrator which imparts or transmits to the semipermeable membrane a preferably continual vibrating motion which preferably acts in the axial direction of the probe.

Abstract: A measuring electrode, especially a glass electrode, having a body detachably connected by means of a coaxial connection device with a connection cable. The part of the connection device arranged at the body is constructed as a plug portion and its inner plug and coaxially arranged outer plug are separated from one another by means of an insulating body. The outer plug is axially rearwardly set back in relation to the end of the insulating body of the plug portion. An insulating body of a bushing portion of the connection device engages in a cap-like manner over the free part of the insulating body of the plug portion.
