| 摘要 |
The invention relates to a transport container (1) comprising a superinsulation in the form of an evacuated insulating container (2) comprising a vacuum maintaining material (55). The transport container is provided with a cooling container (16) comprising a heat-conducting metal wool filling (57) and an organic coolant which undergoes a solid/liquid phase change in the temperature range of between -30°C and -850°C and has a heat of fusion of at least 50 J/ml. A slim cylindrical sample chamber (24) is used to receive deep-frozen tissue samples (26), said chamber being surrounded by the cooling container (16) and merging into a long neck opening (25) forming a single component therewith, said opening being largely filled by the insulating shaft (30) of a screwable plug (28) and sealed from the sample chamber (24). The air in the ring gap (32) created can be evacuated by means of an evacuating system (48). The plug (28) is provided with a stopper (38) protruding into the sample chamber (24) and a data logger (41) for recording the temperature in the sample chamber (24). Following the freezing of the coolant, the transport container (1) enables distribution times and intermediate storage of up to 14 days without any risk of damage to the tissue samples (26) received therein. |
