Dry Ice Information

Dry ice is solid carbon dioxide. It condenses into a colorless liquid at a pressure of 6250.5498 kPa and sublimates at low pressures to form dry ice.

Uses of Dry Ice

Dry ice is utilized in various applications, including:

Artificial rain

Fresh food preservation

Fire extinguishing

Cryotherapy

Preservation of blood plasma and medicines in hospitals

Storage Conditions for Dry Ice

The solidification temperature of dry ice is -78.5°C. It begins to sublimate at temperatures above -78°C. As it sublimates, it turns into a gas that is 600-800 times the volume of its solid form. Therefore, dry ice:

What kind of storage conditions do I need for dry ice?

Because the solidification temperature of dry ice is -78.5, it begins to volatilize when it reaches -78 degrees, it is very easy to volatilize and solidify into a non-toxic, tasteless substance, 600-800 times larger than the solid volume of carbon dioxide gas, So dry ice cannot be stored in completely sealed containers, such as plastic bottles, dry ice and liquid mixes easily, so dry ice must be stored in a special freezer. Dry ice at a temperature below 60 degrees and minus 40 degrees Ultra-low temperature refrigerator can be short-term storage for 5-10 days, but because the temperature is greater than the dissolution point of dry ice, the dry ice will have volatilization, producing Gas, so it is only suitable for short-term storage of small quantities, placed at a temperature below 80 degrees under ultra-low temperature, can be long-term storage.
