Cryopak Phase 22 packs are incredibly useful for shipping live organisms. The phase changing material has a melting point of 22 C or 71.6 F. If heated into a liquid, it will act as a heat pack and release energy. If it is frozen into a solid, it will act as a heat sink and absorb heat energy, providing a cooling effect. These packs will help stabilize any package to room temperature, and can be used strategically with double boxing or in conjunction with a heat pack or cool pack. Ask us how to use Phase packs today!
Please make sure that there is insulation or packing material between a cool pack and live organisms.
