Liquid Nitrogen Container

Liquid Nitrogen Tank

A liquid nitrogen tank is a cryogenic storage container that can be used for preserving and storing semen for an extended period.
The ideal tank for straight cryogenic liquid dispensing
Sizes from 15 litres to 500 litres,Static holding times vary from less than 20 days to more than 300 days.
Convenient fill/withdrawal valve
Easy mobility with sturdy casters and convenient handles
liquid nitrogen containers offer advantages such as easy accessibility for medical purposes, streamlined transportation and loading processes, prevention of contamination, efficient operation, and reliable temperature preservation.

Liquid Nitrogen Container

Standard liquid nitrogen container sizes range from a small 20-litre to a sizeable horizontal tank with 425 litres to store liquefied gases.
A liquid nitrogen container is a specialized type of vacuum flask that stores cryogens such as liquid nitrogen (LN2), whose boiling points are much lower than room temperature.
They are essential for maintaining the extremely low temperature of liquid nitrogen, which boils at −195.79 °C (77 K; −320 °F).
DSW offers a wide range of container sizes, types, and purity grades for both liquid and gas-phase nitrogen with high quality.

This liquid nitrogen container is a good-quality liquid nitrogen tank for laboratory and professional use. It is lightweight, made of aerial-level aluminum alloy, and portable with extended storage time. A wide range of capacities makes it widely used in scientific research, animal husbandry, mechanical processing, etc.

These portable dewars work equally well with liquified gas, liquid oxygen, liquid argon, and liquid nitrogen for low-pressure transport & storage.
Liquid nitrogen is a colorless liquid with an ultra-low boiling point of −320.4 °F that results in freezing anything the substance touches.
Liquid nitrogen is the liquid state of the element nitrogen. Like nitrogen gas, it comprises nitrogen atoms sharing covalent bonds.
In literature, liquid nitrogen is often referred to by the abbreviation LN2, LIN or LN.

It is a transfer vessel that is designed specifically for containing and transporting liquid nitrogen, i.e., it provides carrying handles, pressure relief valves, and venting lids.
These liquid nitrogen Dewars can fulfil many different applications. These are simple, efficient liquid nitrogen dewar that can also be used for liquid oxygen or argon.

The construction of LN2 dewar

Inner Vessel: The innermost chamber is designed to hold the liquid nitrogen securely.
It is typically made of materials that can withstand low temperatures without becoming brittle, such as aluminum or particular stainless steel.
Vacuum Space: Surrounding the inner vessel is a vacuum space that provides insulation to minimize heat transfer and reduce nitrogen evaporation rate.
Outer Jacket: The outermost layer of the container is usually made of sturdy materials like steel or aluminum to protect the inner vessel and provide structural integrity.
Insulation: Superinsulation materials are used between the inner vessel and the outer jacket to provide advanced thermal protection and ensure minimal nitrogen loss56.
Neck Tube: This component joins the inner and outer containers, providing maximum durability and minimum nitrogen loss.

 

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).
Liquid Nitrogen Dewars

Typical applications of LN2 containers:

Scientific Research: Used for experiments requiring low temperatures, such as in physics and biology laboratories.
Medical Facilities: For cryopreservation of biological samples like sperm, eggs, and other genetic material.
Cryosurgery: To remove unwanted tissues such as warts and moles by freezing.
Industrial Processes: In shrink-fitting metal parts, cooling materials during machining, or as a coolant in various manufacturing processes.
Food Industry: For flash-freezing food, preserving freshness, and in molecular gastronomy to create unique dishes.
Cryogenic Storage: To store cells, tissues, and other biological samples for long-term preservation.

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 flask you need. You will need a sturdy metal container called a dewar to purchase liquid nitrogen. Dewar flasks 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).
