Support: Dry Ice FAQs
What is dry ice?
Dry ice is solid carbon dioxide. It is called dry ice because it doesn’t melt into a wet liquid. Dry ice sublimates, which means it goes from its solid form directly to its gaseous form.
Why do I need dry ice for the SimpliPro Colon™ test?
It is necessary to keep the blood samples frozen throughout the shipping process. Dry ice is commonly used to ship items that require freezing.
Is dry ice dangerous?
The surface of solid dry ice is extremely cold. It should not be handled with bare hands. Always wear appropriate protective gloves when handling dry ice. Dry ice should also be used in well-ventilated areas, as it emits carbon dioxide gas into the air. Do not ingest dry ice.
How do I store dry ice?
Dry ice is best kept in an insulated chest or cooler designed for storing dry ice. Do not store dry ice in a freezer, as freezers offer little to no ventilation. Never store dry ice inside a sealed container, as it releases a large volume of carbon dioxide gas as it sublimates.
When shipping the SimpliPro Colon test samples to the lab, place the dry ice directly inside the insulated panels of the shipping box, which should require approximately 5 lbs. Since the box is not air-tight, the gas can escape as the dry ice melts, keeping the pressure in the box low and safe in transit.
How can I dispose of extra dry ice after I have shipped my patient's sample?
It is best to dispose of dry ice in a safe, well-ventilated area to allow the dry ice to sublimate over time. Proper ventilation will decrease the risk of carbon dioxide gas from reaching dangerous levels. Do not add water to the dry ice. Never put dry ice down a sink drain as it can damage pipes.
