Liquid Nitrogen Container
Liquid nitrogen containers, also known as liquid nitrogen tanks or LN2 storage vessels, are cryogenic containers designed for the safe storage and transport of liquid nitrogen at ultra-low temperatures. Standard sizes range from compact 20-liter units to large horizontal tanks with capacities up to 425 liters, allowing users to select the right solution for their application.
These cryogenic liquid nitrogen tanks are widely used for long-term preservation, including biological samples, semen storage, and laboratory materials. Their vacuum-insulated design minimizes heat transfer and reduces liquid nitrogen evaporation, ensuring extended holding time and stable performance.
Design and Construction
DSW liquid nitrogen containers are manufactured from high-strength, aerospace-grade aluminum alloy, making them lightweight, durable, and easy to handle. The double-walled structure with multilayer vacuum insulation provides excellent thermal efficiency, while integrated safety features ensure reliable and safe operation.
Versatile Cryogenic Applications
These portable cryogenic dewars are suitable for low-pressure storage and transport of various liquefied gases, including liquid nitrogen (LN2 / LIN), liquid oxygen (LOX), and liquid argon (LAR). Liquid nitrogen, with a boiling point of −320.4°F (−196°C), is commonly used for rapid freezing, cooling, and cryogenic preservation in scientific and industrial environments.
Safety and Handling
Each liquid nitrogen container is designed as a dedicated transfer and storage vessel, equipped with carrying handles, pressure relief valves, and vented lids. These features allow for safe handling, controlled pressure release, and efficient transport.
DSW liquid nitrogen dewars are simple, efficient, and versatile cryogenic containers, suitable not only for liquid nitrogen but also for liquid oxygen and liquid argon storage across laboratory, medical, agricultural, and industrial applications.

What are cryogenic dewars?
Cryogenic dewar, dewar tanks, or container vessels are designed to store cryogenics (substances with lower boiling points than most).
To achieve this feat, dewar flasks contain an air gap between their outer walls and the liquid stored within, which acts as an insulator for optimal storage conditions.
Cryogenic dewars come in various forms, from household thermoses with two walls separated by a space (such as thermoses used for hot and cold beverages) to complex models designed for specific uses (such as LN2 dewars).

High-Strength Material
The dewar tank is made of aviation aluminum, which has the characteristics of high hardness rustproofness, and can withstand low temperatures.
Well Insulated Dewar
The compound heat insulation of the inner liquid nitrogen tank makes the storage more durable, with fewer welding seams and no vacuum leakage.
Long-Term Preservation
The silicone vacuum nozzle seals the vacuum environment, making this liquid nitrogen tank an ideal low-temperature storage device.
Detail Design
The lockable lid reduces liquid nitrogen evaporation; the enhanced handle is easy to move, and the inside of the bottle stopper is made of PU.
Full Accessories Included
It comes with six canisters, 4 with holes at the bottom, and two sealed canisters. With a bag, this liquid nitrogen tank is portable to carry.
Wide Usage
This nitrogen tank can transport biological samples and refrigeration materials and is also used in the cryogenic processing of metallic materials precision parts.
The liquid nitrogen Dewars is a non-pressurized vessel specifically designed and made of materials that can withstand the extreme temperatures associated with liquid nitrogen.
Liquid nitrogen is odorless, colorless, tasteless, and nonirritating; therefore, it has no warning properties and must be carefully handled.
Determine what size dewar you need. You will need a sturdy metal container called a dewar to purchase liquid nitrogen. Dewars are the safest way to transport liquid nitrogen because they are specially designed to insulate gases (which keeps the LN2 cool) and relieve pressure (which will prevent bursting).
