Liquid Nitrogen Tank

Liquid nitrogen storage tanks are to store liquid nitrogen (LN2) at extremely low temperatures (-196°C or -321°F). These tanks are typically made of high-grade stainless steel or aluminum, featuring vacuum insulation to maintain the cryogenic temperatures necessary for keeping nitrogen in its liquid form. 

What is Liquid Nitrogen Tank?

A Liquid Nitrogen Tank is designed to store liquid nitrogen (LN2) at extremely low temperatures, typically around -196°C (-321°F). These systems are essential for various applications, including cryopreservation, sample storage, and cooling in scientific research and industrial processes.

A liquid nitrogen delivery system is designed to transport liquid nitrogen (LN2) from a storage tank to various points of use. These systems typically include vacuum-jacketed piping, manifolds, and specialized cryogenic equipment to ensure efficient and safe delivery of LN2 at the required flow and pressure.

Why liquid nitrogen delivery system Necessary?

• Efficiency: Ensures a continuous and reliable supply of LN2 to meet operational demands.
• Safety: Minimizes the risk of spills, leaks, and pressure build-up by controlling the flow and pressure of LN2.
• Temperature Control: Maintains the extremely low temperatures required for LN2 to remain in a liquid state during transport.
• Versatility: Can be customized to suit different scales of operation, from small laboratory setups to large industrial plants.

Liquid nitrogen storage systems are used in a variety of settings:

• Laboratories: For cryopreservation of biological samples, such as cells and tissues.
• Medical Facilities: For cryotherapy and cryosurgery.
• Food Industry: For rapid freezing and preservation of food products.
• Industrial Applications: For cooling in processes like semiconductor manufacturing.

Benefits of Liquid Nitrogen Storage Systems

• Cryopreservation: Ensures long-term viability of biological samples.
• Sample Integrity: Maintains sample quality by preventing degradation.
• Versatility: Used in various fields, from medical to industrial applications.
• Safety: Equipped with safety features like pressure relief valves to prevent accidents.

Frequently Asked Questions (FAQs)

What is liquid nitrogen?

Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature of -196°C (-321°F).

Why is proper storage important?

Proper storage ensures safety, maintains the quality of stored samples, and prevents accidents like pressure build-up and explosions.

What are the main types of liquid nitrogen storage vessels?

Cryogenic dewars (portable, short-term storage) and cryogenic tanks (large-scale, long-term storage).

How should liquid nitrogen be handled safely?

Use cryogenic gloves, face shields, and lab coats; ensure proper ventilation; handle with care; and store correctly.

Can liquid nitrogen be used for food preservation?

Yes, it is commonly used for rapid freezing and preserving food products.

What are the risks associated with liquid nitrogen storage?

Risks include pressure build-up, asphyxiation due to oxygen displacement, and extreme cold leaks.

How does liquid nitrogen storage benefit scientific research?

It allows for cryogenic grinding and cooling, enhancing research capabilities.

What is cryopreservation?

The process of preserving biological samples at extremely low temperatures to maintain their viability.

Can liquid nitrogen be used in medical applications?

Yes, it is used in cryotherapy and cryosurgery to treat abnormal tissues.

What is the difference between vapor phase and liquid phase storage?

Vapor phase storage keeps samples above the liquid nitrogen, while liquid phase storage submerges samples directly in liquid nitrogen.

How long can liquid nitrogen be stored?

With proper storage, liquid nitrogen can be stored for extended periods, but it requires regular monitoring and refilling.

What materials are used to construct liquid nitrogen storage vessels?
