AERATED INCUBATOR

An aerated incubator for the cultivation of human or animal cells or tissues is known, having an inner housing which can be closed by means of a door and is surrounded by a heat-insulating outer housing, the outer housing being arranged at a distance from the side walls, the rear wall and the ceiling, and electric heaters being arranged underneath the floor of the inner housing and in the region of the side walls, and having a humidifier device for the atmosphere in the inner space. In order to design an incubator in such a manner that a high relative humidity can be reached in the testing chamber, in which the water can be rapidly and uniformly heated, in which condensation on the inner wall of the container is very largely avoided, and whose heating system can be produced at economical cost, the electrical heating elements are tubular heaters which lie directly against the entire outside of the floor of the inner housing, which has a humidifier device in the form of a trough accepting a water bath, and are angled upwards in the region of the side walls and of the rear wall of the inner housing in such a manner that they project above the floor plane of the inner housing by the height of the water bath and so heat the transitional region between the bottom and the side and rear walls.
