A method for maintaining selectable cold storage temperatures for protracted periods of time using pre-mixed thermal control materials having predetermined melting temperatures equal to the selectable cold storage temperatures is provided. According to preferred embodiments, the thermal control materials are solutions that are filled into cold packs and the solutions are frozen to maintain selected temperatures less than 0° C. The present invention includes methods of storage and transport of materials using the cold packs.
1. A method for maintaining a substance at a cold storage temperature, comprising the steps of: selecting a cold storage temperature to be maintained; preparing a thermal control material having a melting temperature equal to the selected cold storage temperature by determining a molality for a solution whereby the solution of that molality will have a melting temperature equal to the selected cold storage temperature, said thermal control material being the solution; filling a pack with the prepared thermal control material and sealing the pack; an...
