A reagent container assembly adapted for being installed in a cavity of an analyzer. The reagent container assembly comprises a housing having an upper opening and defining at least one circular array of chambers, each chamber being adapted for receiving a reagent container, a cover for closing the upper opening of the housing, and a locking mechanism arranged within the housing. The locking mechanism is adapted for locking the cover and for preventing rotation thereof. The locking mechanism is further adapted for locking the housing and thereby preventing rotation thereof when the reagent container assembly is removed from its position in the analyzer. The locking mechanism is further adapted for cooperating with a pin arranged at the bottom of the cavity of the analyzer when the reagent container assembly is installed in the analyzer, the housing being unlocked by the cooperation and thereby allowed to be rotated within the cavity of the analyzer.

What is claimed is: 1. A reagent container assembly for holding reagent containers and for installation in a substantially cylindrical cavity of an analyzer, the cavity having a bolt arranged at a bottom center thereof, said reagent container assembly comprising: a housing defining at least one circular array of chambers which receive the reagent containers, said housing having a top edge of an upper part defining an opening above said chambers; a cover for said upper opening of said housing, said cover having only a single opening configured to allow removal of a reagent container from one of the chambers in the housing or insertion of the reagent container into one of the chambers of housing; and locking means arranged within said housing, said locking means comprising a locking sleeve and a locking pin, said locking means locks said cover at all times both to prevent rotation of the cover with respect to the analyzer when the reagent container assembly is positioned in said cavity of the analyzer, and to prevent rotation of said cover with respect to said housing when the reagent container assembly is removed from its position in said cavity of the analyzer, and said locking means cooperates with the bolt arranged at the bottom center of said cavity of the analyzer when the reagent container assembly is installed in the analyzer to unlock said housing by said cooperation and to allow rotation of said housing with respect to said cover within said cavity of the analyzer. 2. The reagent container assembly according to claim 1, wherein said housing further defines a recess in which said locking pin in a first state seats to lock the cover relative to the housing, and in a second state unseats from the recess to permit the housing to rotate relative to the cover to allow the array of chambers to rotate within the cavity of the analyzer. 3. The reagent container assembly according to claim 1, wherein the housing has recesses which accommodate projections of the analyzer. 4. The reagent container assembly according to claim 1, wherein the cover has two additional openings allowing taking of reagent volumes from reagent containers contained in the housing of reagent container assembly. 5. The reagent container assembly according to claim 4, wherein the cover has two further openings intended to be gripped by a user for lifting the reagent container assembly. 6. The reagent container assembly according to claim 1, wherein when the reagent container assembly is removed from its position in said cavity of the analyzer the cover rests on the housing of reagent container assembly. 7. The reagent container assembly according to claim 6, wherein the cover rests on a top edge of an upper part of housing of reagent container assembly. 8. The reagent container assembly according to claim 1, wherein when the reagent container assembly is lifted from the cavity of the analyzer the cover separates from an upper part of housing by an air gap, wherein the cover and housing remain locked and cannot rotate with respect to each other. 9. The reagent container assembly according to claim 1, wherein the cover has a first arrow head marker and an upper part of housing has a second arrow head marker, wherein alignment of the first and second arrow head markers together is required for installing the reagent container assembly in the analyzer and for removing it therefrom. 10. The reagent container assembly according to claim 1, wherein when the reagent container assembly is removed from its position in the cavity of the analyzer, the locking sleeve is held by its own weight and end portions of the locking pin are in respective recesses of an upper part of the housing, thereby defining a park state. 11. The reagent container assembly according to claim 10, wherein the recesses of the upper part of the housing are both radial guides for end portions of the locking pin and define the height at which the locking pin is located in the parked state. 12. The reagent container assembly according to claim 1, wherein opposite end portions of the locking pin are different in size. 13. The reagent container assembly according to claim 1, wherein the locking pin is inserted between guides which are part of the cover. 14. The reagent container assembly according to claim 1, wherein the housing has recesses, and the locking pin and the recesses are arranged to define only one possible position in which the locking pin lodge in the recesses. 15. The reagent container assembly according to claim 1, wherein the housing has recesses in a lower part of housing which receive projections of the bolt to ensure that housing can only be connected to bolt at a single, defined angular position of the reagent container assembly with respect to a conveyor of the analyzer.
