Cold Chain Technologies presents a solid phase change material (PCM) to maintain the integrity of drugs and vaccines during transport. The new Koolit advanced PCM gel provides uniform thermal payload protection in a flexible, break-resistant gel pack. Because it is a solid, uniform pack, it provides consistent protection regardless of how it is positioned, and the solid material and break-resistant packaging eliminate leakage. The gel pack’s modularity ensures it can be used for multiple package sizes and shapes, as well as easily wrap around the corners of the product box.
