What type of ice is used for shipment of chilled medical material?

The correct choice for the type of ice used for the shipment of chilled medical material is wet ice. Wet ice is comprised of regular ice that is kept in its solid-state but surrounded by water. This method provides a consistent low temperature and is crucial for maintaining the integrity of sensitive medical items like pharmaceuticals or biological samples. It offers better cooling efficiency compared to other options, ensuring the materials remain at a proper temperature during transit.

Cubed ice is simply frozen water in cube form, which can melt quickly and may not provide the optimal temperature regulation needed for medical materials. Dry ice, although effective at very low temperatures and commonly used for items that require freezing, is not suitable for chilled medical materials, as it can cause freeze damage to items that are not meant to be frozen. Compressed ice is not typically recognized in standard shipping contexts and does not refer to an ice type used for medical shipments. Understanding the specific requirements for maintaining temperature control in transportation is critical in ensuring the safety and efficacy of medical materials.
