Abstract: A heating device includes: a housing configured with an accommodating space having a plurality of space parts; a heating unit disposed in the accommodating space in the housing and operable to generate heat so that temperature of air in each of the space parts of the accommodating space in the housing is maintained to a respective predetermined temperature; a casing configured with an inner receiving space for receiving an object to be heated therein; and a driving unit mounted to the housing for driving the casing to move back and forth in the accommodating space in the housing such that the casing received with the object therein circularly passes through the space parts, thereby circularly heating the object received in the casing at the predetermined temperatures.

Abstract: A micro-scale heating module for heating a micro-fluidic chip is provided. The micro-fluidic chip typically includes an inlet, an outlet and a working region between the inlet and the outlet. The micro-scale heating module includes a preheating part and a heating part. The preheating part is correspondingly disposed on the inlet of the micro-fluidic chip. The heating part connects with the preheating part and surrounds the working region of the micro-fluidic chip in order to make the temperature distribution in the working region uniform. The advantages of the micro-scale heating module include simplicity in design, large flow rate in the working region and large working surface. Therefore, the micro-scale heating module can be used in cell culture, cell-to-pharmaceutical test, biochemical test and so on.
