Abstract:
A device and a method are used for measuring the filling level of a fluid for monitoring a dispense/aspirate process in reaction vessels, including at least one cavity for dispensing and aspirating the fluid, where the cavity is provided with a filling level sensor whose signals, transmitted to an evaluation unit, are evaluated to determine the filling level, the at least one cavity is assigned a receiving body which is closed at the bottom and is separated from the cavity for receiving the fluid, the filling level sensor is at least one thermistor extending along the outside of a wall of the receiving body without coming in contact with the fluid, the evaluation unit evaluates the temperature influence of the thermistor in dispensing, aspirating and in retention of the fluid in the receiving body to detect the filling level, in this way the process monitoring in washing the reaction vessels is improved.
