Where to Buy Liquid Nitrogen?
Liquid nitrogen is commonly available at plumbing supply stores, industrial gas suppliers, and sometimes local universities. Prices usually start around $1 per liter, and purchase conditions may vary, including container requirements.
1. Plumbing Supply Stores
Plumbing supply stores often stock liquid nitrogen. Plumbers use it to clear drain blockages by freezing and breaking up clogs. These stores cater to non-industrial customers needing smaller amounts. Prices are typically affordable, often about $1 per liter. Some stores allow purchases only if customers bring their own insulated container, like a vacuum flask or insulated tub. Availability can vary, so calling ahead is recommended.
2. Industrial Gas Suppliers
Major industrial gas suppliers such as Air Gas, Linde, and Praxair provide liquid nitrogen in bulk. These companies serve laboratories, manufacturing, and medical industries. They can supply large volumes and offer delivery services. Pricing depends on quantity and delivery method, but remains competitive. Customers usually require a contract or account to purchase from these suppliers.
3. University Laboratories
Some universities produce liquid nitrogen onsite for scientific research. Access to this supply is generally limited to internal users. However, establishing contact with university laboratory staff or departments may make it possible to obtain small amounts, such as a thermos. This option works best for educational or experimental needs where large purchases are unnecessary.
Pricing and Purchase Conditions
- Typical price: around $1 per liter
- May require bringing your own container
- Purchase availability depends on local regulations and supplier policies
Summary of Sources
| Source | Typical Use | Quantity Available | Pricing |
|---|---|---|---|
| Plumbing Supply Stores | Drain blockage clearing | Small, retail quantities | Approx. $1/L, container may be needed |

| University Laboratories | Research and educational use | Small amounts on request | Usually free or nominal charge |
Key Takeaways
- Plumbing supply stores sell liquid nitrogen mainly for clearing drains.
- Industrial gas suppliers like Air Gas and Linde provide bulk liquid nitrogen to labs and industries.
- Local universities may allow access to small amounts for research purposes.
- Prices usually start near $1 per liter, with some sellers requiring appropriate containers.
- Contacting suppliers ahead ensures availability and understanding of purchase policies.
Where to Buy Liquid Nitrogen? The Ultimate Guide to Sourcing This Cool Commodity
If you’re wondering where to buy liquid nitrogen, the answer depends on how much you need and what you’re using it for. But here’s the gist: you can grab liquid nitrogen from plumbing supply stores, industrial gas suppliers, or even your local university lab. It’s more accessible than you might expect.
Let’s break down the options, prices, and a few insider tips to make your quest for liquid nitrogen a breeze. Spoiler alert: it’s often cheaper than milk, but it’s definitely cooler.
Plumbing Supply Stores—Your Unexpected Nitrogen Pit Stop
First stop: plumbing supply stores. Yes, it sounds odd, but plumbers actually use liquid nitrogen for a neat trick—breaking up drain blockages. Imagine clogged pipes, and then *boom*, nitrogen to the rescue by freezing and cracking stubborn gunk. They’re one of the biggest non-industrial users, so these stores often keep some liquid nitrogen stock on hand.
Smaller quantities are available here, and sometimes, you can buy from them if you bring along your own insulated container, like a vacuum flask or insulated tub. Not all shops will sell off the cuff, so calling ahead is wise.
Why plumbing stores? Because liquid nitrogen can freeze water quickly and create pressure to clear pipes—making it a plumber’s secret weapon. If your needs are modest and plumbing related, this stop is definitely worth considering.
What Does Liquid Nitrogen Cost?
| Source | Price per Liter | Buying Conditions |
|---|---|---|
| Plumbing Supply Store | Approx. $1.00 | Bring your own container, usually |
| Industrial Gas Suppliers (e.g., Praxair, Air Gas, Linde) | Generally $1 or less per liter (bulk pricing) | Minimum order might apply |
| University Labs | Varies, often free or low cost if personal contact | May require permission or special arrangements |
Yes, liquid nitrogen is about $1 per liter. That price occasionally surprises folks because it’s actually less expensive than many common household liquids, like milk. However, watch out for buying conditions. Some places won’t sell unless you supply an approved container — safety first! This could be a fancy vacuum flask or a professional dewars flask designed for cryogenic liquids.
Industrial Gas Suppliers: The Go-To for Larger or Lab Needs
For labs and industries, industrial gas suppliers like Air Gas, Linde, and Praxair dominate the scene. These companies aren’t just selling nitrogen; they offer high-quality, pure-grade liquid nitrogen, perfect for experiments, manufacturing, or culinary uses.
Our lab friends swear by Praxair. They buy in bulk, which means prices can get better with volume. But beware: they might have minimum order sizes, and the purchase process usually involves paperwork, safety certifications, and a proper transport container.
Think of these suppliers as the grocery store for liquid nitrogen lovers, but with a *membership card* and safety gear required.
Universities: A Hidden Vault of Liquid Nitrogen
You might not have thought about this, but university labs often produce their own liquid nitrogen. Chemistry and physics departments especially keep it stocked for experiments. If you happen to know someone there, or can get in touch with a lab manager, you could score a thermos or small container filled with this chilly marvel.
This option requires some networking skills and a bit of luck. Not every university will sell or share it readily, but those who do often like helping out hobbyists, researchers, or students. Keep in mind, this might be the most cost-effective or FREE source if you have campus connections.
Quick tip: If your chemistry teacher or a university professor has a flask lying around, it doesn’t hurt to ask nicely!
How to Safely Transport and Store Liquid Nitrogen
Here’s one thing you don’t want to skip: safety. Liquid nitrogen can cause severe frostbite and can displace oxygen in enclosed spaces. Whenever you buy it—whether plumbing store, industrial supplier, or university lab—make sure you have a proper insulated container.
Vacuum flasks or specialized Dewar containers keep liquid nitrogen from boiling off too quickly. Don’t attempt to use ordinary bottles or thermoses; they’re not designed for such cold temps.
Also, transport liquid nitrogen in a well-ventilated area, and avoid sealed containers that can explode due to pressure buildup.
Still Wondering Where to Buy Liquid Nitrogen?
If you’re asking yourself, “But where exactly do I start?”, here’s a practical checklist:
- Determine your volume needs—small hobby quantity or industrial-size?
- Start with your local plumbing supply store for small amounts and quick grabs.
- Check online for industrial gas suppliers like Praxair, Air Gas, and Linde, especially if you need more than a few liters.
- Hit up your local university science labs—networking might get you a great deal!
- Always bring or buy the appropriate container. Don’t trust plastic water bottles here.
- Prioritize safety—handle with care, even if you just want to impress friends with some “cryogenic magic.”
Finding liquid nitrogen doesn’t have to be a mysterious scavenger hunt. Whether you’re a plumber clearing a pipe, a scientist doing cool experiments, or a curious foodie making nitrogen-frozen desserts, sources are out there. The price and ease of purchase largely depend on your usage and local suppliers.
Parting Thought
Liquid nitrogen feels like magic because it’s so cold and versatile. But it’s also a commodity, bought and sold quietly at plumbing stores, scientific hubs, and industrial suppliers alike. So next time you ask “Where to buy liquid nitrogen?”, picture those plumbers unblocking pipes and chemists chilling test tubes. It’s all connected.
