<p>A system for crystallogenesis by diffusion, intended in particular for use on board a space ship, and in which a substance to be crystallized contained in a crucible (18) is brought into contact with a precipitating agent. This crystallogenesis system comprises: at least one receptacle (4) in communication with the means for admitting the precipitating agent (2, 3, 8, 9, 10, 11) and the means for evacuating the precipitating agent (12, 13); at least one leakproof capsule (17) containing at least one such crucible (18) and filled with the precipitating agent, the said crucible containing the said substance to be crystallized; and means of connection (5, 6, 7, 23) which enable the interior of the said capsule (17) to be connected automatically to the said means for admitting (2, 3, 8, 9, 10, 11) and to the said means for evacuating (12, 13) the precipitating agent, when the said leakproof capsule (17) is introduced into the said receptacle.</p> |
