  • Patent number: 9720008
    Abstract: This disclosure provides automatic analyzers and reagent wheels thereof. The reagent wheel can have one or more rings of reagent bottle seats that may be used for placing a reagent container and distributed along a circumferential direction. An included angle may be formed between a symmetrical centerline of the reagent container placed on the reagent bottle seat and a radius of a circle where the reagent wheel is located, where the included angle is not equal to zero. Compared with the situation in which the symmetrical centerline of the reagent container overlaps with the radius of the circle where the reagent wheel is located, an improved balance can be achieved between the capacity and the diametric size of the reagent wheel, thus making an improvement in meeting application requirements of the analyzers.
