Liquid nitrogen tank is a specialized equipment used for storing and transporting liquid nitrogen gas, widely used in various fields such as scientific research, medical care, food, and industry. Choosing the appropriate liquid nitrogen tank can not only improve work efficiency, but also ensure safety and service life. When making a purchase, capacity, material, and safety are the most critical considerations. This article will provide you with a comprehensive purchasing guide to help you find the most suitable liquid nitrogen tank for your needs.

1. Choose the appropriate capacity
The capacity of a liquid nitrogen tank directly determines its storage capacity and usage time, therefore, the appropriate volume should be selected according to actual needs.

Laboratory and medical use: It is usually necessary to store cells, tissues, vaccines, etc. It is suitable to choose small liquid nitrogen tanks ranging from 10L to 50L, which are easy to move and manage.

Industrial applications, such as metal cold treatment and electronic manufacturing, typically require larger capacities, such as large liquid nitrogen tanks of over 100L, to meet high-intensity production needs.

Transportation and portability requirements: If frequent movement of liquid nitrogen is required, it is recommended to choose a portable liquid nitrogen tank with a capacity generally between 5L-20L and equipped with convenient handles or rollers.

2. The influence of material on performance
The material of the liquid nitrogen tank determines its durability, insulation performance, and impact resistance. At present, liquid nitrogen tanks on the market are mainly made of the following materials:

Aluminum alloy: lightweight, strong corrosion resistance, suitable for fine application scenarios such as laboratories and biomedicine.

Stainless steel: With higher strength and superior pressure resistance, it is suitable for industrial production and environments that require high-strength storage.

High performance composite materials: Some new liquid nitrogen tanks use multi-layer composite materials, further improving insulation and durability.

3. Ensure safety
The safety of liquid nitrogen tanks is crucial, and the following points should be considered when purchasing:

Vacuum insulation design: High quality liquid nitrogen tanks should have a double-layer vacuum insulation structure to reduce liquid nitrogen evaporation and improve storage efficiency.

Safety valve and pressure relief device: can prevent the risk of overpressure caused by liquid nitrogen evaporation, ensuring safe use.

Sealing performance: Check the sealing of the tank to prevent liquid nitrogen leakage and avoid frostbite or low-temperature injury.

Seismic design: If frequent movement of liquid nitrogen tanks is required, models with seismic support structures should be selected to avoid collision damage.

summarize
Choosing a suitable liquid nitrogen tank requires comprehensive consideration of capacity, material, and safety. After clarifying the usage scenario, choose the appropriate capacity while ensuring that the tank material is durable, has good insulation performance, and safety measures. High quality liquid nitrogen tanks can not only improve work efficiency, but also reduce liquid nitrogen loss and ensure safe use. When making a purchase, it is recommended to choose products produced by reputable manufacturers to ensure quality and reliability.
