Abstract: The present invention pertains to a sensor vessel for the optical detection of biomarkers, preferably nucleic acids and/or proteins. The sensor vessel can be used for example to optically detect a biomarker, for example a marker for a disease, a virus, a MRSA, a parasite, and the like, with high accuracy in an environment or subject.

Abstract: The invention relates to a device for filling a tank with a liquid medium, in particular a urea solution, comprising a filling pipe and comprising a suction channel for removing air from the tank. The invention is characterized in that at least one air guiding element is provided inside the suction channel, said air guiding element being designed to deflect the air transversely to the longitudinal axis of the filling pipe.

Abstract: A filling head 10 is described for filling in a liquid into a filler neck of a tank 14. To ensure highly reliable operation, a rotary connecting element 26 is provided to form a mechanical connection by rotating in relation to the filler neck of the tank 14. A rotatable operating part 30 serves to rotate the rotary connecting element 26. The operating part 30 is coupled to the rotary connecting element 26 by means of a torque-limiting coupling device 32 that, given a threshold torque, is triggered at least in one direction of rotation and decouples the rotatable operating part 30 from the rotary connecting element 26. A sensor is provided to detect the triggering of the torque-limiting coupling device 32 and to send a release signal for the established connection.
