Reagent tray for biochemical analyzer, biochemical analyzer composed of reagent tray, and method for positioning reaction cavity

The invention discloses a reagent tray for a biochemical analyzer, a biochemical analyzer composed of the reagent tray, and a method for positioning a reaction cavity, for solving the problems that the existing biochemical analyzer is low in measurement efficiency and high in equipment input cost. The reagent tray comprises a tray cover, a water cup, a tray base and the reaction cavity, wherein the tray cover is connected with the tray base, the water cup is arranged in the middle of the tray base, and the reaction cavity is arranged in the tray base and distributed in a radial shape. The reagent tray also comprises a tray light blocking ring at the upper part of the tray cover, wherein a through hole corresponding to the reaction cavity is formed in the tray light blocking ring. The invention further provides the biochemical analyzer composed of the reagent tray and the method for positioning the reaction cavity. The reagent tray is ingenious in structure and convenient to operate, the ...
