Introduction
We offer a 3.15 L Cryogenic Liquid Nitrogen (LN2) Dewar Tank that can store your LN2. The tank is designed using Dewar technology; insulating process involving a vacuum between two interior walls.
Our tank, made of aircraft-grade aluminum, includes 6 straw-attached canisters for specimen storage and an insulated padded cover with straps to reduce LN2 loss. Portable and lightweight, it weighs 7.5 lbs. empty (13 lbs. full), ensuring easy handling.
Applications
Liquid Nitrogen (LN2) is a versatile element with a wide range of applications, from scientific research to culinary arts. Our LN2 Dewar Tank is ideal for storing temperature-sensitive materials, such as biological samples, and is widely used in educational experiments, food preparation, and industrial processes. Whether you're creating smoky cocktails, making ice cream, or conducting lab experiments, this tank provides reliable and efficient LN2 storage.
Here, we highlight two key fields:
- Culinary field: Liquid nitrogen's culinary use stems from its freezing properties, creating creamy frozen foods with microscopic ice crystals. It's favored in gourmet restaurants for crafting ice creams due to its superior ability to produce a velvety texture unmatched by ice cream machines.
- Medical Field: Liquid nitrogen is widely used in the medical field for preserving biological samples and in various cryogenic applications, making it an essential tool for scientific research and industrial processes.
Features
- Capacity: The U.S. Solid Cryogenic Liquid Nitrogen Tank holds up to 3.15L of LN2.
- Dewar Design: Specially engineered to store extremely cold liquids like LN2 with a slower evaporation rate, thanks to its shape, capacity, and durable materials.
- Evaporation Rate:Fully tested by filling the tank and monitoring nitrogen loss over time.
- Canisters: Includes 6 canisters—4 perforated for biological specimens and 2 sealed for dipping applications.

User Manual and Precautions
For more information about the product, please refer to the User Manual. And please check the Notes and Cautions before and during use.
Please note:
- This cryogenic container ships empty and can be filled at any liquid nitrogen supplier.
- Ensure adequate ventilation during use.
- Cryogen Protective Gloves are recommended to prevent skin contact with liquid nitrogen.
- Upon receiving the tank, pre-cool it with 2/3 liquid nitrogen to test the vacuum.
- Fill with LN2 to precool before use and let it stand for 48 hours.

Evaporation Rate
Statistics
We tested our cryogenic container by filling it with liquid nitrogen. The evaporation rate was determined at room temperature without moving or opening the vessel. We then continuously weighed the container every day to determine the amount of liquid nitrogen that evaporated. The actual holding time varies depending on:
- the presence of canisters
- the size, temperature, and heat capacity of the samples
- the surrounding temperature and humidity
- any movement during sample changes or transport

Handle with care. Keep it cold.
I vacillated and vacillated and finally bought this. Was not sure that 3L dewar for $144 was going to be a decent value. 3L of LN cost about $20. It has now kept the liquid nitrogen in a liquid state for eight days, even after we used portions of it. We only removed the plug briefly in order to transfer LN to another container. Yhe plug is a plastic cap with a long "styrofoam" insert. The dewar was kept in a cool environment. it is my assumption that if you live in a hot climate, and you keep it in a warm atmosphere, that the liquid nitrogen will evaporate faster. I am very happy with this purchase. Very good value. It is not meant for long term storage. Read more

I had been nervous as to how well the tank would store medical grade liquid nitrogen. It��s been 8 weeks since I filled it and it still has plenty left, enough for another 8 weeks at least. Extremely important to put the lid on the metal perforated canister, otherwise the vials will float inside the tank. Use only one, max 2 canisters so they do not get tangled. Plus, there is no need for 6, one or 2 is enough. One alone can hold 12, 1ml vials. Read more
