A device for biochip hybridization or washing is provided, which comprises a carousel (12), a translational movement controller, a revolving movement controller, and optionally a heating chamber (13). The revolving movement controller controls the revolving movement of the carousel and allows it to move in a wobbling fashion, allowing liquid movement of the hybridization or washing boxes (11) during hybridization and/or washing of biochips on the carousel. The translational movement controller brings the carousel back to horizontal position once the revolving movement controller stops, thereby ensures that the liquid do not spill out. The heating chamber circulates hot air within the device, thereby ensures that the hybridization and washing in a thermostatic condition.
