Shaking device

A device for shaking, within a rigid container, content comprising a material in powder form and a liquid product, for the purpose of conducting a test on the shaken content, said container having a capacity of less than one liter and able to hold an amount of content suitable for conducting the test, comprising:

• a frame,
• a first plate assembled directly or indirectly to the frame,
• a second plate assembled indirectly to the frame, arranged close to the first plate and movable relative to the frame and to the first plate, and
• a drive unit suitable for moving the second plate relative to the frame and to the first plate, wherein,—the container is carried by the second plate and is movably mounted relative to the second plate,
• the first plate comprises a stop, said stop being arranged near to and facing the container, the stop being fixedly mounted on the first plate, and
• the second plate is moved relative to the first plate by the drive unit, in an alternating and repeating translational and/or rotational motion between a proximal position and a distal position, so as to move the container relative to the second plate and cause a series of impacts between the container and the stop in order to achieve a non-periodic shaking of the container by the alternating and repeating motion of the second plate.
