Abstract: An automated device for deconcentration and potentiation of homeopathic remedies, comprising a preparations flask held by a support fastened to a horizontal shaft driven in rotation. The mouth of the flask describes a circle and can be moved among several positions, particularly an original position for introduction of the dose to be diluted or rediluted and for introduction of the solvent, and a position for pouring the dilution into a wide-mouth bottle containing granules to be impregnated and put into rotation. Between each deconcentration, the flask is cleaned by washing means and drying means located on its path in other positions.
