The invention relates to an in-situ microscope device for reactors, especially bioreactors, comprising an immersion tube in a reactor connecting port, which, inside the reactor, has an inlet for a sample area. The microscope device also comprises a microscope outer tube, which is coaxially placed inside said immersion tube and which, on the inner end with the objective, is directed toward the sample area that is located between an objective cover glass and an object support glass body arranged opposite the same. The exterior of the microscope outer tube is connected to a camera for recording the image of the sample area, whereby the objective cover glass and the object support glass body can move in relation to one another in order to permit an opening and closing of the sample area. The invention provides that a rinsing chamber (7) having closeable openings (8), through which cleaning agents can be introduced, is connected to the exterior of the reactor connecting port (6), and that the immersion tube (2) can move in an axial direction inside the connecting port (6) and can be retracted until the inlet (4) is in contact with the rinsing chamber (7) in order to enable a cleaning of the sample area. Sealing means (9, 9') are provided on the immersion tube in order to keep the inside of the reactor sealed from the rinsing chamber (7) when the immersion tube is retracted to the rinsing chamber.
