The application relates to the field of biotechnology, and discloses an exosome concentration detection kit, a detachable double-cassette main body, which comprises a cassette-type main body I and a cassette-type main body II; the cassette-type main body I is provided with valve gas transmission pipes on both sides, an internal waste liquid collecting bin and a collecting interface bin are arranged in the inner cavity, an optical detection window is detachably assembled on the top through fixing bolts, a chip card slot is arranged on the opposite surface of the main body II, and a fluorine rubber sealing ring is attached to the inner wall of the card slot; and a reagent bin fixing groove and a sample adding port are arranged on the top of the cassette-type main body II. The mechanical cooperation of the detachable double-cassette main body and the automatic fluid control equipment realizes the pre-packaging and fixing of all complex reagent pipelines in the cassette, the user does not need to manually pipette or connect any pipeline, only three actions of "adding a sample, putting the detachable double-cassette main body, and one-key starting" are needed, and the fluid control equipment can automatically complete puncture, sealing, fluid time sequence control and valve switching of up to 7-8 steps.
