The Freezers

Manual cold caps can be used at any location with the dry ice method. However a biomedical freezer is of benefit to both patients and infusion centers. It saves patients/helpers the cost and effort of acquiring and handling dry ice, keeps all caps uniformly cold, and minimizes the number of helpers needed by the patient. Of note, both methods work equally well.

The cold cap process requires any freezer that can maintain a temperature of -30°C (-22°F). (Note that each cap has to be stored in its own box to ensure uniform temperature throughout.). Specifications for the freezer that The Rapunzel Project generally donates are as follow:

  • Model Number 34-13CCF, white chest style freezer
