- Nitrogen is to be dispensed only into smaller Dewars which either (a) have carrying handles or (b) are on wheels or (c) are 500 mL or smaller, and which have pressure relief valves or pressure venting lids. ...
- Ensure the door to the room housing the liquid nitrogen storage tank is open.
How is liquid nitrogen distributed?
Liquid nitrogen is distributed and stored in insulated containers. The insulation reduces heat flow into the stored nitrogen; this is necessary because heat from the surrounding environment boils the liquid, which then transitions to a gaseous state.
Can you put liquid nitrogen in a plastic container?
Impact resistant containers that can withstand the extremely low temperatures should be used. Materials such as carbon steel, plastic and rubber become brittle at these temperatures. Only store liquid nitrogen in containers with loose fitting lids (Never seal liquid nitrogen in a container).
What is required to transfer liquid nitrogen from a low pressure container?
Transfer of Fluids • All cryogenic cylinders must have pressure relief valves and burst discs to release excessive pressure. All dewars must be approved for liquid nitrogen use and have loose fitting lids.
Can I buy a small amount of liquid nitrogen?
Dermatology supply companies offer a hot-cold container (“Thermos”) to store liquid nitrogen for use in examination rooms. ... These containers can cost between $36–$45 from medical supply companies.
Can you buy liquid nitrogen over-the-counter?
Liquid nitrogen is not available over-the-counter. Instead, the product that removes warts in a similar process uses dimethyl ether. It only cools to about 59 degrees below zero Celsius, whereas liquid nitrogen reaches approximately 195 degrees below zero Celsius. Both will cause serious injury if used improperly.Apr 12, 2011
Can we buy liquid nitrogen?
Liquid nitrogen is not an over-the-counter product, so you may not know gas what types of stores supply it. Companies like Praxair and Airgas distribute gases to customers all over the world, however, so there may be a supplier near you.

Can liquid nitrogen be purchased over-the-counter?
Liquid nitrogen is NOT available over-the-counter. Instead, the product that removes warts in a similar process uses dimethyl ether (DME). It only cools to about -59 C, whereas liquid nitrogen reaches approximately -195 C. Both can be dangerous and will cause serious injury if used improperly.Apr 12, 2011
Is it safe to pour liquid nitrogen on your hand?
You can also pour it on your hand. As long as you do it quickly it will not hurt you and will boil the nitrogen instead. ... A person is so much hotter than liquid nitrogen that the liquid nitrogen immediately boils away and doesn't freeze your hand.
Is liquid nitrogen safe on skin?
Liquid nitrogen has a boiling temperature of -196°C at atmospheric pressure. Direct contact can freeze the skin causing frostbite and cold burns. Delicate tissue, such as eyes, can be damaged by an exposure to the cold gas alone which would be too brief to affect skin.
Is liquid nitrogen harmful for body?
The vapor of liquid nitrogen can rapidly freeze skin tissue and eye fluid, resulting in cold burns, frostbite, and permanent eye damage even by brief exposure.
