ChemicalsNitrogen is used to pressurize pipelines in order to help propel liquids and to help purge piping and equipment to prevent contamination. Partnering with Priority Energy Services, we offer quality nitrogen backed by a constant, consistent supply from mobile nitrogen pumpers.
Life SciencesAs a gas, nitrogen is used as an essential component in various life science processes as well as a protectant against oxidation and contamination. In liquid form, nitrogen is also used to achieve cryogenic temperatures in reactor cooling application.
We hand-craft each ice cream and milkshake to provide a fully customized option. We are making ice cream fun for everyone. For adults, we specialize in alcohol-infused ice cream & milkshakes that start at a 5% ABV. We encourage our guests to get creative with over 30 available flavors and enjoy the fun the innovative use of liquid nitrogen offers. The possibilities are truly endless.
Liquid phase nitrogen can be supplied in individual pre-filled liquid cylinders and refillable Dewars. For larger supply requirements, liquid nitrogen can be delivered to small onsite cryogenic vessels (MicroBulk) or large scale cryogenic vessels (bulk tanks). For the largest scale liquid nitrogen requirements, onsite nitrogen production is available and cost effective (onsite plant design, construction, maintenance).
For smaller requirements, pre-filled liquid cylinders are a versatile supply option. Liquid cylinders dispense nitrogen in either gas or liquid phase. Refillable, portable Dewars service some applications.
Play aside, liquid nitrogen (LN2,) like other forms of nitrogen, is a useful substance that fits several home uses and features in several industrial applications. However, LN2 is not readily available in grocery stores because the material is potentially hazardous and must be handled with care.
As the name implies, liquid nitrogen is the liquid state of the element nitrogen. Like nitrogen gas, it is made up of nitrogen atoms sharing covalent bonds. In literature, liquid nitrogen is often referred to by the abbreviation, LN2 or LIN or LN.
The substance was first liquefied by Polish physicists Zygmunt Wróblewski and Karol Olszewski on April 15, 1883. Since then, liquid nitrogen has gained popularity and increased usage thanks to its low temperature and its ability to quickly freeze other substances on contact.
For secure storage, liquid nitrogen comes in insulated containers that incorporate pressure venting to prevent pressure buildup. Depending on the efficiency of the containment system, stored LN2 can last anywhere from a few hours to a couple of months.
Because of the Leidenfrost effect, liquid nitrogen will not burn you on immediate contact with skin. The rapidly evaporating gas thermally insulates your skin for a brief instant saving you temporarily from cold burns. This effect is similar to the temporary protection you get from touching a hot object with a wet finger for a microsecond. However, the more prolonged exposure that results from LN2 pooling anywhere on your skin will lead to severe cold burns.
Furthermore, you must never swallow liquid nitrogen. Ingesting LN2 can lead to freezing of tissues and severe internal damage. In 1997, a physics student accidentally consumed liquid nitrogen and suffered near-fatal injuries. Similarly, in 2012, one English teen had her stomach operated after drinking a cocktail made with liquid nitrogen.
Furthermore, because of this expansion, liquid nitrogen storage containers must be pressure vented at all times. In 2006, malfunctioning pressure-relief devices of liquid nitrogen tank resulted in a massive explosion at a lab in Texas A&M University. The blast was powerful enough to remove the walls of the lab, shatter a reinforced concrete beam underneath, and propel the nitrogen tank through the ceiling.
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.
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.
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. Hence, nitrogen is often more ideal for maintaining an even pressure distribution. The great thing about tire dealerships is that you can find them almost everywhere. Even better, a well-stocked dealership might have a few dewars for sale.
Another excellent place to check for LN2 is any store that sells welding supplies. Many large scale welding operations use liquid nitrogen. Hence, you are quite likely to get a refill at a supply store. However, welding supply stores that carry the product typically cater to high volume purchases. So, there is no guarantee that they will be willing to take up micro orders.
While supermarkets do not have liquid nitrogen on offer, like with many products, Costco is sometimes an exception. Depending on what part of the country you are in, your local Costco may double as a hardware store or even gas station. Like some tire dealerships, some Costcos are also using nitrogen to fill tires in place of oxygen. If you are in luck, you can even get dewars at some outlets.
Another perfect place to inquire is at your local universities or colleges. Science laboratories on campuses often stock their supply of liquid nitrogen for various researches. Your local college may have some on offer for sale, and they often do so at significantly less than market prices. You could try checking the school website for info or calling their Physics and Chemistry departments.
It is never safe to directly eat or touch liquid nitrogen in any way. Think of it like fire. Both fire and liquid nitrogen are sources of extreme temperatures and can cause a lot of harm. However, it is safe and reliable for food when handled properly.
Liquid nitrogen looks like steamy water and may appear harmless, but it can quickly freeze whatever it touches. Although the fog is safe, the actual liquid is not due to its extremely low temperature. So, make sure to never directly come into contact with or ingest liquid nitrogen and leave the freezing to the food. Enjoy responsibly!
The smoking, liquid-nitrogen treat called Dragon's Breath that kids beg for at kiosks at malls, fairs and festivals across America is dangerous to the point of being life-threatening, the U.S. Food and Drug Administration warned with a recent alert.
Your doctor will use either a cotton swab or a spray \"cryogun\" to apply liquid nitrogen to the wart and some of the skin around it. This may feel like an ice cube touching your skin, but it only lasts a few seconds. Your skin may feel numb briefly and may also hurt, turn red, then form a blister.
You can also get cryotherapy products to remove warts at home. Over-the-counter kits use dimethyl ether propane instead of liquid nitrogen. They probably aren't as effective as the treatment you will get from your doctor in their office.
We offer compressed nitrogen gas and liquid nitrogen (N2) in a variety of purities and concentrations. Download Safety Data Sheets or see the chart below to download the spec sheets for more information on buying liquid nitrogen and nitrogen gas.
Used as a pressurizing gas, nitrogen can help propel liquids through pipelines. It is also used to shield oxygen-sensitive materials from the air and to remove volatile organic chemicals from process streams.

Q: You recently had a column indicating the use of liquid nitrogen for the removal of seed warts and that it is available at pharmacies without a prescription. You have got to be kidding me! Where My local pharmacy acted as if I was an alien asking for moon dust. I thought maybe it was the Freeze Away over-the-counter, but they indicated that was not liquid nitrogen. Please help.
A: I apologize for the confusion. 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. 59ce067264
