An analysis device for in vitro diagnosis, comprising: - at least one rack intended to receive a plurality of containers equipped with sealing elements and containing samples of biological liquid to be analyzed, - a loading module arranged to move the at least one rack between a loading position and a first intermediate position along a first movement direction transverse to the plane of the at least one rack, - a shaking module arranged to move the at least one rack between the first intermediate position and a second intermediate position and to shake the at least one rack, the shaking module being arranged such that the at least one rack extends substantially along a same orientation in the first and second intermediate positions, the shaking module including: - guiding means arranged to guide in translation the at least one rack between the first and second intermediate positions along a guiding direction, - translational driving means arranged to drive in translation the at least one rack between the first and second intermediate positions along said guiding direction, and - an unloading module arranged to move the at least one rack between the second intermediate position and an unloading position along a second movement direction transverse to the plane of the at least one rack, and - a sampling module arranged to take samples of biological liquid in the containers received in the at least one rack, characterized in that the shaking module further including pivoting means arranged to pivotally drive the guiding means around a pivot axis, and in that the analysis device further comprising: ∘ a loading rotor disposed between the loading and unloading modules (14, 37) and of a substantially vertical axis of rotation, and rotation driving means associated with the loading rotor and arranged to drive in rotation the loading rotor around its axis of rotation, the loading rotor comprising a plurality of housings able to receive containers containing samples of biological liquid to be analyzed or reagent products, the sampling module being arranged to take samples or reagent products in the containers received in the loading rotor, and/or ∘ a preparation and measuring module including: - a preparation rotor of a substantially vertical axis of rotation, the preparation rotor comprising a plurality of preparation cuvettes, the sampling module being arranged to supply the preparation cuvettes with samples of biological liquid or reagent products previously taken, and - rotation driving means associated with the preparation rotor and arranged to drive in rotation the preparation rotor around its axis of rotation. - at least one rack intended to receive a plurality of containers equipped with sealing elements and containing samples of biological liquid to be analyzed, -
