Phase-change materials are used to preserve temperature-sensitive items such as biological specimens without subjecting the latter to extreme heat or extreme cold. Such use provides active thermal control due to melting and solidification of the phase-change materials at constant temperature.

1. A use of a phase-change material for maintaining in a container an at least one temperature sensitive item at a preselected temperature as close as possible to ambient temperature to minimize heat transfer with respect to the ambient temperature without causing any temperature-related damage to the at least one item. 2. The use according to claim 1, wherein the at least one item is selected from the group consisting of animal parts, human body parts, body fluids and biological cultures. 3. The use according to claim 1, wherein the phase-change material is selected from a group consisting of: n-Tetradecane 1-Decanol n-Pentadecane Chloroacetic acid-o-Cresol eutectic Tetradecylbenzene Sodium Chromate Decahydrate n-Octanoic Acid chloroacetic acid-phenol eutectic Acetic Acid Salt mixture of 37% NaSO 4, 17% NaCl, 46% H 2 O 1-Octadecene Glycerol n-Hexadecane Polyethylene Glycol 600 Double Clathrate of water with Tetrahydrofuran and Hydrogen Sulfide Lithium Chloride ethanolate n-heptadecane Copper Nitrate Hexahyrate Lactic Acid Manganous Nitriate Hexahydrate n-Octadecane Methyl Palmitate 3-Methylpentacosane Orthophosphoric Acid Hemihydrate Lithium Nitrate Trihydrate Calcium Chloride Hexahydrate Gallium Sodium Solfate Decahydrate Levulinic Acid n-Eicosane Sun Wax P-116. 4. A method of using a phase-change material, comprising the steps of (a) lining a container with the phase-change material, selected to have a phase-change temperature as close as possible to ambient temperature to minimize heat transfer with respect to the ambient temperature without causing any temperature-related damage to contents of the container; (b) placing at least one temperature-sensitive item constituting the contents inside the container; and (c) sealing the container to insulate an interior thereof from ambient temperature. 5. The method according to claim 4, wherein the phase-change material is selected from a group consisting of: n-Tetradecane 1-Decanol n-Pentadecane Chloroacetic acid-o-Cresol eutectic Tetradecylbenzene Sodium Chromate Decahydrate n-Octanoic Acid chloroacetic acid-phenol eutectic Acetic Acid Salt mixture of 37% NaSO 4, 17% NaCl, 46% H 2 O 1-Octadecene Glycerol n-Hexadecane Polyethylene Glycol 600 Double Clathrate of water with Tetrahydrofuran and Hydrogen Sulfide Lithium Chloride ethanolate n-heptadecane Copper Nitrate Hexahyrate Lactic Acid Manganous Nitriate Hexahydrate n-Octadecane Methyl Palmitate 3-Methylpentacosane Orthophosphoric Acid Hemihydrate Lithium Nitrate Trihydrate Calcium Chloride Hexahydrate Gallium Sodium Solfate Decahydrate Levulinic Acid n-Eicosane Sun Wax P-116. 6. The method according to claim 4, wherein the at least one item is selected from the group consisting of animal parts, human body parts, body fluids and biological cultures. 7. The method according to claim 5, wherein the at least one item is selected from the group consisting of animal parts, human body parts, body fluids and biological cultures.
