If there is not a nearby branch, you can also search the internet and/or your local Yellow Pages for a distributor that services your location.
Search the websites of your local university’s chemistry and physics departments. They will usually have instructions on who to contact, and may even have an online order form for liquid nitrogen purchases. If you can’t find any information about liquid nitrogen purchasing on the department’s website, you can also try calling their main office. Most university departments have a phone number listed on their main page.
Dewars typically range from 3. 6 litres (0. 95 US gal) to 50 litres (13 US gal) in size. Never store liquid nitrogen in a fully-sealed container. This would result in an excess of air pressure, and cause the container to burst. [5] X Research source
Prices for dewars vary depending on their size, but usually cost at least $200USD and usually more. If you don’t purchase liquid nitrogen often, you might want to consider renting a dewar. Places that sell liquid nitrogen often have dewars available to rent.
When shopping online, it’s best to buy from certified sellers with high ratings, in order to ensure quality and reliability.
Some places will even require an open vehicle, such as a truck, for transporting liquid nitrogen. [6] X Research source Check the policy of your local supplier before driving over in a hatchback. You can always ask your liquid nitrogen supplier if they offer home delivery.
If you are ordering liquid nitrogen delivered to your home or workspace, the supplier will deliver it to you in the dewar you requested.
