Liquid Nitrogen Tank Selection Guide: From Beginner to Proficient, Teach You to Choose the Most Suitable Liquid Nitrogen Tank

25-Feb-25


Liquid nitrogen tanks, as specialized containers for storing liquid nitrogen, are widely used in fields such as biological samples, medical care, and scientific research. How to choose the most suitable liquid nitrogen tank for oneself when facing the dazzling array of liquid nitrogen tanks on the market? This article will provide a detailed analysis of the key points for purchasing liquid nitrogen tanks, from beginner to expert.

 

1、 Clarify requirements and determine types

Storage type vs. transportation type: Storage type liquid nitrogen tanks are mainly used in fixed places such as laboratories, with large capacity and excellent insulation performance; Transport type liquid nitrogen tanks place greater emphasis on portability and seismic resistance, with relatively smaller capacities.

Gas phase vs. liquid phase: Gas phase liquid nitrogen tanks store gaseous nitrogen at relatively high temperatures, suitable for samples such as cells that do not have strict temperature requirements; Liquid nitrogen tanks store liquid nitrogen at temperatures as low as -196 ℃, suitable for samples such as embryos and stem cells that require extremely high temperatures.

 

2、 Focus on core parameters

Capacity: Choose the appropriate capacity based on sample size and storage time to avoid insufficient capacity or waste.

Caliber: Large caliber is convenient for accessing samples, but has a higher evaporation rate; Small caliber evaporation rate is low, but accessing samples is relatively inconvenient.

Static evaporation rate: The lower the evaporation rate, the slower the consumption of liquid nitrogen, and the lower the cost of use.

Material: High quality aluminum alloy material is lightweight, strong, and corrosion-resistant, making it the preferred material for liquid nitrogen tanks.

Vacuum degree: The higher the vacuum degree, the better the insulation performance, and the lower the liquid nitrogen evaporation rate.

 

3、 Details determine success or failure

Lock cover design: A well-designed lock cover can effectively prevent liquid nitrogen evaporation and ensure sample safety.

Protective cover: The protective cover can prevent frosting on the surface of the liquid nitrogen tank and avoid frostbite to personnel.

Accessories: Lifting tubes, freezing racks, and other accessories can facilitate the access and management of samples.

 

4、 Brand and Service

Choose a well-known brand: The product quality and after-sales service of well-known brands are more guaranteed.

Pay attention to after-sales service: Liquid nitrogen tanks are precision instruments, and comprehensive after-sales service can solve your worries.

 

5、 Safe use

The temperature of liquid nitrogen is extremely low, and protective equipment should be worn during operation to avoid frostbite.

The liquid nitrogen tank should be placed in a well ventilated area to avoid use in confined spaces.

Regularly check the vacuum degree and sealing of the liquid nitrogen tank to ensure safe use.

 

summarize

Choosing a liquid nitrogen tank requires comprehensive consideration of personal needs, product parameters, brand services, and other factors. I hope this article can help you choose the most suitable liquid nitrogen tank to safeguard your sample storage.
