The invention relates to a disc type reaction device. The device comprises a reaction disc mechanism and two uniform shaking mechanisms, wherein the reaction disc mechanism comprises a circular barrel, and a circular plate which is rotatably arranged in the circular barrel; each uniform shaking mechanism comprises a charging mechanism and a discharging mechanism which are positioned on one side of the circular barrel; a heating mechanism is arranged; the arc length distance of one uniform shaking mechanism to the charging mechanism is 1/3 to 1/4 of a circle, and the arc length distance between the two uniform shaking mechanisms is 2/3 to 3/4 of a circle; the distance from the second uniform shaking mechanism to the discharging mechanism is equal to the size of a reaction cup storing hole; the distance from the charging mechanism to the discharging mechanism is equal to the size of the reaction cup storing hole. According to the disc type reaction device, the two uniform shaking mechanisms, the charging mechanism and the discharging mechanism are reasonably arranged, and the requirements on washing, refilling of reaction solutions, and space between the charging position and the discharging position, as well as the time requirement, are completely met.
