摘要
This disclosure relates to a system for freezing, transporting, storing and thawing aqueous solutions of biological materials, in particular those used in chemical and pharmaceutical processes. In particular, this disclosure relates to ice-crust attenuator devices to prevent ice- crust formation at the top of the solution. The ice-crust attenuator devices (10) have an internal cavity comprising a phase change material to improve thermal insulation. The ice-crust attenuator device may comprise an internal wall made of a moldable material configured to attain a good thermal contact between the ice- crust attenuator device and the outer surface of the container. In another embodiment, the ice-crust attenuator device is configured to be placed in a refrigerated cavity and in contact with the upper surface of a moldable container, to keep the top of the container under insulated conditions. The ice-crust attenuator device may be connected to a holder to accommodate the moldable container.
