Abstract
A thermal transport device having a hollow within which a plasma storage freezer is deployed. The freezer acts as a cold "battery" by having a eutectic fluid contained therewithin. The freezer is placed in a commercial, powered refrigeration unit for chilling ("charging") the eutectic fluid of the plasma storage freezer to approximately -30.degree. C. The freezer is then deployed within the thermal transport device and sent to a remote locale for collecting blood plasma. Blood plasma is disposed between a central heat sink and lateral heat sinks of the freezer freezing the blood plasma quickly and maintaininig its initial high quality because of negligible time loss for freezing. Ultimately, the device is returned to a commercial powered refrigeration unit for ("recharging") rechilling the eutectic fluid for subsequent reuse.
