Abstract:
1. Handheld apparatus for the preparation of an electrochemical sensor comprising a sensor head in order to provide the sensor head with an electrolyte and a membrane, the apparatus comprising a holder for the sensor, a dispenser for the electrolyte, a dispenser for the membrane and a common carrier, wherein: the holder, the dispenser for the electrolyte, the dispenser for the membrane and the common carrier are arranged within a common housing that is able to be handheld with the common housing comprising a housing upper part and a housing lower part being mutually rotatably mounted in a direction of rotation, the housing upper part being capable of being moved by hand in the direction of rotation, the housing upper part and the housing lower part each comprising a half shell which form a common inner space for the reception of at least the dispenser for the electrolyte, the dispenser for the membrane, the common carrier and the holder for the sensor; the holder is fixedly arranged in said housing lower part, with the housing lower part comprising an opening where the opening leads to the holder to engage the electrochemical sensor; the housing upper part further comprising an actuator which is displaceably mounted essentially in the vertical direction with respect to the housing upper part and the housing lower part; and the dispenser for the electrolyte and the dispenser for the membrane are arranged within the common carrier within said common housing, the common carrier has an operative connection to the housing upper part in order to rotate the common carrier in the direction of rotation if the housing upper part is rotated in the direction of rotation, the common carrier, comprising the dispenser for the electrolyte and the dispenser for the membrane, is rotatably mounted in the housing lower part in said direction of rotation in order to position the dispenser for the electrolyte and the dispenser for the membrane in sequence with respect to the sensor held in the holder by manually moving the housing upper part in the direction of rotation, and to supply the electrolyte and membrane to the sensor by manually moving the actuator in said vertical direction by downward pressing exerted onto the actuator with the actuator comprising a plurality of plungers capable of either linear or rotational movement in connection with the actuator, wherein:
