1. A reaction processing apparatus comprising:
a reaction processing vessel including a channel in which a sample moves and a pair composed of a first air communication port and a second air communication port that are provided at respective ends of the channel;
a first heater in thermal contact with the channel;
a second heater in thermal contact with the channel;
a temperature control system connected to and configured to control the first heater to heat a first temperature region to a first temperature and the second heater to heat a second temperature region to a second temperature higher than the first temperature, the first temperature region and the second temperature region are disposed along the channel between the first air communication port and the second air communication port; and
a liquid feeding system configured to move and stop the sample in the channel,
wherein the liquid feeding system includes:
a single pump having a discharge port configured to discharge air;
a first air channel that connects the discharge port of the single pump and the first air communication port of the reaction processing vessel;
a second air channel that connects the discharge port of the single pump and the second air communication port of the reaction processing vessel;
a first switching valve that is arranged in the first air channel and is configured to switch between a state in which the first air communication port communicates with the discharge port and a state in which the first air communication port is opened to atmospheric pressure;
a second switching valve that is arranged in the second air channel and is configured to switch between a state in which the second air communication port communicates with the discharge port and a state in which the second air communication port is opened to the atmospheric pressure; and
a control unit operatively connected to the pump, the first switching valve and the second switching value and configured to operatively control the single pump, the first switching valve, and the second switching valve.
