Detailed ways

The specific embodiment of the utility model:

As shown in Figures 1-3, the reagent bottle used for the immunoassay analyzer in this embodiment is made of black light-proof high-density pp material, including a smaller bottle body 1, a larger bottle body 2, and a smaller bottle body. The bottle body and the larger bottle body are connected to each other. The bottom of the larger bottle body is designed to be inclined to the bottom of the smaller bottle body. The bottom 3 of the smaller bottle body is lower than the deepest part 4 of the larger bottle body. The smaller bottle body is used for the reagent arm. For sampling, the larger bottle is used to expand the liquid volume, and the liquid contained in the larger bottle has no residue.

The smaller bottle described in this embodiment has a cylindrical body with a smooth cylindrical bottom, and its opening is higher than the top surface of the larger bottle. A lid is provided on the opening for sealing the reagent bottle.

The larger bottle body described in this embodiment includes cavity one 5 and cavity two 6, cavity one has a gradually larger cavity, and cavity two is a flat rectangular body that communicates with the cylinder and the gradually larger cavity.
