FAQ
Q: What is a liquid nitrogen tank used for?
Liquid nitrogen tanks are used across a wide range of industries: preserving biological samples (cells, tissue, sperm, embryos) in labs and medical facilities, freezing food quickly in commercial kitchens, cryotherapy in dermatology, cooling materials in industrial machining, and demonstrations in education. Smaller dewars are also popular for culinary use and DIY projects.
Q: Can anyone just buy liquid nitrogen?
In most countries, yes — liquid nitrogen is not a controlled substance. You can purchase it from industrial gas suppliers (such as Air Liquide, Praxair, or local welding supply shops) without a special license. However, suppliers may require you to bring your own approved dewar, and some vendors prefer commercial or institutional customers. Age restrictions may apply depending on your region.
Q: What is a dewar of liquid nitrogen?
A dewar is a double-walled, vacuum-insulated container specifically designed to store cryogenic liquids like liquid nitrogen (LN₂) at extremely low temperatures (−196 °C / −321 °F). The vacuum between the walls dramatically reduces heat transfer, keeping the contents cold for days to weeks. They come in sizes ranging from 1-liter lab flasks to large 200-liter cylinders.
Q: How much does a dewar of liquid nitrogen cost?
The dewar vessel itself ranges from around $100–$300 for small 10–30 L units to $1,000–$3,000+ for large industrial cylinders. The liquid nitrogen inside typically costs $0.30–$1.00 per liter when purchased from an industrial gas supplier, though prices vary by region and volume. Many suppliers also offer rental dewars.
Q: How long can liquid nitrogen sit in a dewar?
It depends on the dewar's insulation quality and size. A well-maintained dewar will hold LN₂ for anywhere from a few days (small, older units) to several weeks (large, high-quality vessels). All dewars experience some evaporative loss — this is normal. Never seal a dewar airtight, as pressure buildup from evaporation can be dangerous.
Q: Why can't we touch liquid nitrogen?
At −196 °C, direct contact causes immediate cryogenic burns — tissue freezes almost instantly, similar in severity to a thermal burn. Prolonged contact destroys cells and can cause permanent damage. Always wear insulated cryogenic gloves, a face shield, and closed-toe shoes when handling LN₂. Splashes are also a risk, so protective eyewear is essential.
Q: Can you eat something after it's been in liquid nitrogen?
Yes — once all the liquid nitrogen has fully evaporated, the food is safe to eat. LN₂ itself is non-toxic (it's just nitrogen, which makes up 78% of the air we breathe). The danger is consuming food while LN₂ is still present, which can cause severe internal cold burns. Always wait until the visible "smoking" effect has completely stopped before eating.
Q: Is using a dewar suitable for beginners?
With proper training and safety equipment, yes. Beginners should start with small dewars, always work in well-ventilated areas (LN₂ displaces oxygen as it evaporates), and never leave a dewar sealed. Reading the supplier's safety data sheet (SDS) and following your institution's or supplier's handling guidelines before first use is strongly recommended.
