Where is liquid nitrogen sold

Hence, it is common to use oxygen sensors as a safety measure when working in confined spaces. When working with liquid nitrogen, please take the following precautions to avoid any potential risks:. LN2 is typically available for bulk purchase at a few specific locations. However, to buy liquid nitrogen, you must already have a particular cryogenic storage metal container called a dewar.

This device serves as a way to prevent explosions from the rapid expansion of the liquid to gas. A dewar is a specialized type of vacuum flask that is used to store cryogens i. These dewars use multiple designs that incorporate a high vacuum between two or more layers to maintain reliable thermal insulation between the interior and exterior of the container.

Popular types of dewars include open bucket dewars, flasks with loose-fitting stoppers and self-pressurizing tanks. Dewars are the safest way to transport cryogens like LN2 as they significantly reduce the rate at which the contents boil away.

Never store liquid nitrogen or any other cryogen in a fully-sealed container as this will cause the tank to burst. Before going on your hunt for liquid nitrogen, first, you must determine how much and consequently how large a dewar you need. Dewars typically range from 0. A standard dewar like the U. Solid liter will set you back at least bucks.

Alternatively, you can reach out to your local liquid nitrogen supplier to see if they have dewars at hand. Once you have secured your dewar, the next step is finding a place that sells LN2. Liquid nitrogen is usually sold by the liter for anywhere from 30 cents to a dollar per liter. However, depending on how scarce LN2 is in your area, the price may be significantly higher. While liquid nitrogen is not available over the counter, some distributors like Praxair and Airgas that specialize in distributing gases often stock it.

You can use the store locator on the company websites, search the internet, or consult the yellow pages to find a distributor near you. One unconventional location where you may find liquid nitrogen in abundance is at tire dealerships. Some tire dealerships use nitrogen in place of oxygen for filling tires. These dealerships do this because nitrogen migrates through your tire slower than oxygen. We highly recommend purchasing your dewar before sourcing your nitrogen so that you can transport it effectively.

Also, keep in mind that the liquid will evaporate no matter what, so you want to use it as quickly as possible.

Once exposed to the air, it will start turning into a gas — this is the fog effect you see when looking at it. If you have never used this stuff before, plan to have some fun with it before you start mastering your technique. Please log in with your username or email to continue. No account yet?
