An in-situ microscope device for reactors, especially bioreactors, having an immersion tube in a reactor connecting port, which, inside the reactor, has an inlet for a sample area, also a microscope outer tube, which is coaxially placed inside the 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. Also included is a rinsing chamber having closeable openings, through which cleaning agents can be introduced, is connected to the exterior of the reactor connecting port, and that the immersion tube can move in an axial direction inside the connecting port and can be retracted until the inlet is in contact with the rinsing chamber in order to enable a cleaning of the sample area.
