The storage comprises, from the bottom to the top, a low temperature storage zone (6) for storing the samples, a handling zone (7) housing at least part of an automatic transport device (9) and an access zone (8) where the user can enter for maintenance. A separating wall (14) consisting of removable panels (15) insulates the access zone (9) for the rooms below it. A peripheral housing (2) contains a peripheral chamber (50) for temporarily storing the samples at slightly higher temperatures. A liquid nitrogen container (4) is used to feed dry gas to the storage zone and to maintain it under slight overpressure for preventing the entry of moisture. |
