How to Buy Dry Ice?
Carbon dioxide is a gas that makes up 0.041% of the Earth’s atmosphere by volume, and dry ice is carbon dioxide in a solid state. You can use the substance to do a variety of things, from instantly making fog to flash-freezing food, and it is simple to purchase.
Buying and Transporting Dry Ice
Visit your neighborhood grocery or general merchandise store to purchase dry ice. Stores that sell dry ice include Safeway, Walmart, and Costco.
- Plan to purchase dry ice as close to your anticipated need as possible. Due to its constant sublimation (transition from solid to gas), it has a very short shelf life. Every 24 hours, 5–10 pounds of dry ice sublimate.
- Although the majority of people can buy dry ice, some shops will demand that you be at least 18 years old.
Purchase dry ice blocks. Blocks of dry ice are needed for both conducting academic experiments and producing fog effects.
- Although it is also available in pellet form, dry ice is primarily used for medical transportation or dry ice blasting to clean surfaces.
- Dry ice can cost anywhere between $1 and $3 per pound. Prices may vary according to quantity and location, but they are typically reasonable.
A plastic cooler or ice chest should be used to hold the dry ice in an insulated container. Since carbon dioxide freezes at -109.3 degrees Fahrenheit or -78.5 degrees Celsius, a standard refrigerator or freezer won’t significantly increase its shelf life. It is significantly colder than a refrigerator, which is typically 40 degrees Fahrenheit (4.4 degrees Celsius), or a freezer, which is typically 32 degrees Fahrenheit (0 degrees Celsius).
- Never handle dry ice with bare hands; always wear gloves.
- The dry ice will sublimate more slowly the thicker the insulation is in your cooler or ice chest.
- In order to slow down the sublimation process, the container should be opened and closed as little as possible. To reduce dead space and slow down sublimation, you can also stuff the cooler’s open spaces with wadded paper.
- Your freezer’s thermostat might turn off if you store dry ice there. Due to the extreme cold of dry ice, your freezer will turn off to prevent food from becoming too frozen. Therefore, you can put dry ice inside your freezer and it will function as a replacement if your freezer breaks down and you need to keep the food inside frozen.
Roll down the windows in your car and put the cooler inside. Keep in mind that carbon dioxide, which makes up dry ice, is dangerous if inhaled in large amounts.
- If you are transporting dry ice for more than 15 minutes, it is especially crucial to have access to fresh air. When breathed in for an extended period of time while in a poorly ventilated area with dry ice, it can result in rapid breathing, headaches, and even death.
Handling Dry Ice
When pouring or opening dry ice, wear long sleeves and leather gloves. Even though brief contact is safe, prolonged contact with skin can cause cell freezing and a burning sensation akin to fire.
- The protection provided by gloves is superior to that of an oven mitt or towel, though both can be used. Avoid skin contact with dry ice, just as you would with a hot frying pan.
- Burns caused by dry ice should be treated the same as other burns. If your skin is only red, it will eventually heal. Apply antibiotic ointment and bandage the area if your skin blisters or comes off. In the event of severe burns, seek medical attention right away.
Keep dry ice that isn’t being used in well-ventilated areas. An oxygen-deficient environment can result from storing large amounts of dry ice in airtight spaces.
- Your backyard storage shed will have good airflow and won’t put people or animals in danger of suffocation. Ask your school’s chemistry teacher if there is a secure place to store dry ice if you are having trouble finding a good place to keep it.
- Make sure to keep dry ice out of the reach of little ones and animals.
In a room where dry ice has spilled, open the doors and windows. Although it must be able to mix with the air more readily, the dry ice will continue to sublimate.
- Since dry ice is heavier than oxygen, it will gather in the spill area’s low spots. As these places will have the highest concentration of carbon dioxide, keep your face away from pits and other low, enclosed areas.
To get rid of dry ice, place it in a place with good ventilation and let it sit at room temperature. If you have extra dry ice, keep in mind that it is constantly sublimating and only needs to be left alone for it to evaporate.
- You can get rid of dry ice on your porch in the backyard. For at least a day, make sure it is safely out of reach of others.
- Dry ice disposal is also possible in a fume hood. In a fume hood, dangerous chemicals can be stored or used in a ventilated area. You might be able to store the extra dry ice in the fume hood in the chemistry lab at your school. Make sure you first ask a teacher before doing that.
Things to Avoid
In an entirely airtight container, do not keep dry ice. The container will expand and possibly explode as a result of the dry ice being sublimated into carbon dioxide.
- When compressed too tightly, dry ice has the potential to erupt violently. Some people have been brought up on felony criminal charges for purposely confining dry ice until it explodes, creating a dry ice “bomb.”
- Dry ice should not be kept in metal or glass containers as an explosion could result in shrapnel that could cause serious cuts or other injuries.
Do not store dry ice in garages, basements, cars, or other places with poor ventilation. If breathed exclusively, the carbon dioxide produced by the dry ice can suffocate you as it gradually starts to replace oxygen in the bloodstream.
- Before going inside, let storage spaces that once held dry ice breathe.
Refrain from leaving dry ice unattended. Spills and other accidents can happen even when no one is present if strict supervision is not provided.
- Avoid leaving dry ice on tiled or solid surface countertops because the extreme cold may cause cracking.
Dry ice should never be thrown away down the drain, toilet, or garbage disposal. The water in the pipes will probably freeze, and you might even cause them to burst.
The extreme compactness of a pipe will also cause dry ice to expand quicker and may cause an explosion
How Long Does Dry Ice Last?
The duration of dry ice varies depending on a number of variables, including packaging, air pressure, ambient temperature, and insulation thickness.
Your dry ice’s lifespan can be ascertained by talking to a dry ice specialist, like those at CryoCarb.
What Should You Remind Dry Ice Safety?
- Ensure that you always handle dry ice safely!
- Store dry ice in a cooler with the loosely closed. NEVER use an airtight container: the build-up of carbon dioxide gases as the dry ice sublimates could cause the container to burst!
- Place the cooler as far away from heat sources as you can.
- Your freezer is NOT a place to keep dry ice! The freezer will be shut off by the thermostat as a result.
- NEVER store dry ice inside a closed container or in a room. While transporting any of this substance, keep the windows of your car closed.
- After storing dry ice, leave it outside or in a bucket of water in a well-ventilated area for disposal.

FAQs About Dry Ice
Where Can I Buy Dry Ice?
There are numerous grocery and general merchandise stores that sell dry ice. It’s likely to be available at larger chains like Costco and Walmart, but some smaller chains might not have any on hand. One can get dry ice directly and with certainty by contacting a dry ice supplier.
What is Dry Ice Made Of?
CO2 is used to create dry ice. The gas is forced to condense into liquid form by industry professionals using high pressures and extremely low temperatures (109°F) during the manufacturing of dry ice. The CO2 is then injected into a pelletizer or block press, where it is compressed into solid blocks.
How Much Dry Ice Do I Need?
Product weight, packaging, and duration of use are just a few of the variables that affect how much dry ice is required for a particular application. Depending on the precise application, these factors also change.
Taking the quantity required to keep food fresh as an illustration, keeping things frozen is different. Finding out how much dry ice is necessary for a specific application can be made easier by working with a dry ice expert.
