Dry ice, the solid form of carbon dioxide (CO₂), plays a crucial role in the transportation and storage of temperature-sensitive medical supplies. With a temperature of -78.5°C (-109.3°F), dry ice provides a reliable, non-mechanical cooling solution for vaccines, blood, organs, and pharmaceuticals during shipping. It is widely used in cold chain logistics, ensuring that biological samples and critical medications remain at stable, ultra-low temperatures throughout transit. Unlike traditional ice, dry ice sublimates directly into gas, leaving no liquid residue, making it ideal for sterile environments. This makes dry ice indispensable in global healthcare supply chains, ensuring life-saving medical materials reach their destinations safely and effectively.
