The invention claimed is: 1. An apparatus for the automated clinical analysis of samples comprising: a circular reagent store having concentric rings for carrying reagent containers; a rotatory carousel having grooves for carrying reaction containers; a reaction container entry device adjacent the rotatory carousel for supplying the reaction containers by means of a detachable rack containing the reaction containers, wherein the reaction container entry device comprises a reaction container pushing device for feeding the rotatory carousel by pushing the reaction containers from the detachable rack towards the grooves of the rotatory carousel; a reagent arm device in a radial arrangement with respect to the circular reagent store, being capable of polar displacement for linking the reagent containers and the reaction containers and for moving the reaction containers out of the rotatory carousel; a scanning device concentric with the rotatory carousel capable of scanning reaction containers moved into the scanning device from the rotatory carousel by the reagent arm device; a linear arm device capable of rectilinear movement for linking tubes carrying samples with the reaction containers; a table for the entry and exit of supports for the tubes carrying samples, the table having a means for automatic displacement of said supports towards a continuous feeder for feeding the supports towards the linear arm device for pipetting the samples to the reaction containers; and a control unit for controlling the apparatus, wherein the reagent arm device comprises an end pushing device for pushing the reaction containers out of the rotatory carousel for removal. 2. The apparatus for the automated clinical analysis of samples according to claim 1, wherein the reaction container entry device comprises two arcuate supports adjacent to the rotatory carousel, each of said arcuate supports being capable of receiving the detachable rack containing reaction containers, the detachable rack being accessible to the reaction container pushing device which is displaceable over a toothed segment radial with respect to the circular reagent store and the rotatory carousel. 3. The apparatus for the automated clinical analysis of samples according to claim 2, wherein the detachable rack comprise a plurality of straight columns joined at one face by means of a laminar wall, the columns thereby being capable of curving on said face in order to adapt to the arcuate supports, a bottom of each column having retaining flanges for retaining the reaction containers, and apertures for allowing the reaction containers to exit the detachable rack. 4. The apparatus for the automated clinical analysis of samples according to claim 3, wherein each column comprises aligned apertures in an outer face and in an inner face, the aligned apertures being of smaller dimensions than the reaction containers. 5. The apparatus for the automated clinical analysis of samples according to claim 1, wherein the temperatures of the reagent store and the rotatory carousel are independently thermostatically controlled by the control unit. 6. The apparatus for the automated clinical analysis of samples according to claim 1, wherein the table for the entry and exit of supports for the tubes carrying samples comprises a magnetic means for passing the supports for the tubes carrying samples to a continuous feeder equipped with a plurality of seats for the supports, the plurality of seats being moveable on the table to transport the tubes carrying samples to and from the linear arm device. 7. The apparatus for the automated clinical analysis of samples according to claim 6, wherein each support for the tubes carrying samples comprises a self-centering receptacle for one of the tubes carrying samples and a magnetic means on a base which permits interaction with the magnetic means of the table. 8. The apparatus for the automated clinical analysis of samples according to claim 7, wherein the self-centering receptacle comprises a plurality of vertical arms operative to establish contact with one of the tubes carrying samples, said vertical arms being rotatable synchronously to thereby produce a self-centering effect. 9. The apparatus for the automated clinical analysis of samples according to claim 8, wherein the vertical arms are rotatable about a lower axes and extend in toothed segments which mesh with a gearwheel arranged centrally to produce the synchronisation of rotation of the vertical arms. 10. The apparatus for the automated clinical analysis of samples according to claim 1, wherein the linear arm device comprises a longitudinally displaceable arm carrying a probe, the arm being operative to collect a sample by passing the probe through a stopper covering a top of one of the tubes carrying samples to thereby extract the sample by pipetting, the arm being further operative to transport the collected sample to one of the reaction containers. 11. An apparatus for the automated clinical analysis of samples comprising: a circular reagent store having concentric rings for carrying reagent containers; a rotatory carousel having grooves for carrying reaction containers; a reaction container entry device adjacent the rotatory carousel for supplying the reaction containers by means of a detachable rack containing the reaction containers, wherein the reaction container entry device comprises a reaction container pushing device for feeding the rotatory carousel by pushing the reaction containers from the detachable rack towards the grooves of the rotatory carousel; a reagent arm device in a radial arrangement with respect to the circular reagent store, being capable of polar displacement for linking the reagent containers and the reaction containers and for moving the reaction containers out of the rotatory carousel; a scanning device concentric with the rotatory carousel capable of scanning reaction containers moved into the scanning device from the rotatory carousel by the reagent arm device; a linear arm device capable of rectilinear movement for linking tubes carrying samples with the reaction containers; a table for the entry and exit of supports for the tubes carrying samples, the table having a means for automatic displacement of said supports towards a continuous feeder for feeding the supports towards the linear arm device for pipetting the samples to the reaction containers; and a control unit for controlling the apparatus, wherein the reagent arm device has a radial structure with respect to the circular reagent store and further comprises a means for rotation and radial displacement of the reagent arm and a probe for collecting reagents to be deposited in at least one of the reaction containers, and wherein the reagent arm device has an end pushing device for pushing the reaction containers out of the rotatory carousel for removal.
