Abstract: A nucleic acid loading device, including a housing, a carrying module, a motion module, a liquid circuit module and a control module. The motion module includes a support platform, first and second driving mechanisms, and a carrying member. The liquid circuit module is configured to control a reagent to flow into and out of a reactor. The control module is connected with the motion module and the liquid circuit module, and the control module is configured to control the first and second driving mechanisms, the liquid circuit module and the temperature control unit. A first face of a semiconductor cooler heats or refrigerates during operation, providing heat for an accommodating seat through a heat conducting body such that the reactor can be at different ambient temperatures. The cooperation between the motion and liquid circuit modules may achieve automation and industrialization of loading a sample into the reactor.
