摘要： The invention concerns a cryogenic system (1) for vitrifying a substance comprising biological material to be preserved in a receiving region of a thin tube (8), comprising a tank (10) containing a bath (11) of a cryogenic agent and a support member (80) mounted on said tank in a predetermined first position in which said tube is orientated upright, the receiving region being immersed in a liquid zone (17) of said bath, and an opening of said tube being situated above said bath, in a zone of ambient air above said bath, in order to introduce the substance into the tube, the support member being mounted on said tank in a second predetermined position, in which said receiving region is immersed in the liquid zone and said opening is situated immediately above said liquid zone, in a gaseous zone (18) of said bath above said liquid zone and below said zone of ambient air, and being raised from said second position
