Isovation validates the isothermal performance of packaging for the transport of temperature-sensitive products, primarily in the healthcare sector (vaccines, medications, samples, organs, etc.) that must be maintained or transported at very low temperatures, from -21 to -80°C and/or for long periods. We offer a complete range of single-use or reusable isothermal packaging, the effectiveness of which has been validated in the laboratory.
Dry ice is carbon dioxide in a solid state. The carbon dioxide naturally present in compressed air becomes liquid and then cools to solidify at a temperature of -80°C. This is why dry ice sublimates when it passes from a solid state to a gas, because in ambient air, the pressure is no longer high enough to transform it into a liquid state. In other words, the dry ice cube at -80°C will diffuse a temperature of -80°C inside the insulated packaging until it disappears completely, leaving no trace of water. Ultimately, dry ice acts as a super cold accumulator inside the insulated packaging.
Thanks to its -80°C diffusion, dry ice offers multiple possibilities: transporting for longer or transporting colder. While insulated packaging equipped with 0°C or -21°C cold accumulators will ensure temperature maintenance for periods of 24 to 96 hours, dry ice can go even further, up to 190 hours. Our design office and sales team can determine the quantity of dry ice you need if necessary.
If your transport time and/or temperature exceed the limits of traditional ice packs, our design office will provide a proposal using dry ice. Also, if you don’t want to manage freezing cold packs because your shipments are one-off or your insulated box can’t accommodate cold packs (transporting frozen desserts on airplanes, constraints on the external dimensions of the packaging that prevent it from accommodating a battery, etc.), you can use dry ice.
To maintain the cold chain, dry ice ensures effective cold diffusion inside the validated insulated packaging. The transportation of healthcare products (vaccines, organs, biological samples, etc.) requires, depending on the transport conditions, ambient temperatures, and duration of transport, insulated packaging approved at -80°C to ensure their stability.
Dry ice must be handled with care. Its temperature of -80°C can cause frostbite; be sure to wear gloves and appropriate equipment to reduce the risk of accidents.
