Transport Container For Keeping Frozen Material Chilled

摘要

Disclosed is a transport container for shipping frozen material, particularly biological tissue samples. Said transport container comprises a jacket-shaped insulation (superinsulation) and a removable inner container (44) which is provided with at least one coolant chamber (47) with a coolant filling (47′), and at least one chilling chamber (46) that is located inside the coolant chamber (47). The coolant, e.g. mercury having a melting temperature of about −39° C., is permanently and hermetically enclosed in the coolant chamber (47) and is solidified in a freezing process using liquid nitrogen, for example, before being shipped. The chilling chamber (46), and thus the sample, is maintained at said temperature level during shipping while the coolant or mercury melts slowly.
