Abstract:
In-situ microscope device for reactors, with a dip tube which is insertable into a reactor connection port and has an inlet, in the end-section pointing to the inside of the reactor, for a specimen zone, and a microscope external tube, arranged coaxially in the dip tube, which at the inner end is directed with a lens towards the specimen zone which lies between a lens cover glass and a slide glass body lying opposite in the dip tube, and at the opposite end is coupled with a camera, lying outside the dip tube, for photographing the image of the specimen zone, the lens cover glass and the slide glass body being movable relative to each other, in order to be able to open and close the specimen zone, characterized in that connected outside to the reactor connection port (6) is a rinsing chamber (7) with sealable openings (8) through which cleaning agents can be fed in, and the dip tube (2) is movable in axial direction in the connection port (6) and can be pulled back until the inlet (4) communicates with the rinsing chamber (7) in order to be able to clean the specimen zone, sealing means (9, 9â€²) being provided at the dip tube in order to keep the internal space of the reactor sealed off from the rinsing chamber (7) if the dip tube is pulled back to the rinsing chamber.
