A comprehensive inventory of liquid nitrogen tank types: advantages and disadvantages of different types of liquid nitrogen tanks and application scenarios

        As a special container for storing liquid nitrogen, liquid nitrogen tanks have a wide variety and each has its own advantages. This article will take stock of different types of liquid nitrogen tanks for you, analyze their advantages and disadvantages and application scenarios, and help you make the best choice according to your own needs.

1. Classification by caliber

        Large diameter liquid nitrogen tank (diameter ≥ 125mm):

Advantages: It is convenient to store samples and can accommodate larger-sized frozen storage racks. It is suitable for storing large samples or large-sized biological materials.

Disadvantages: The liquid nitrogen has a high evaporation rate and a relatively high cost of use.

Application scenarios: places where biological sample banks, hospitals, scientific research institutions need to store large amounts of samples.

        Small diameter liquid nitrogen tank (diameter < 125mm):

Advantages: Liquid nitrogen has low evaporation rate, low cost of use, and good portability.

Disadvantages: It is relatively inconvenient to store samples, and the size of the frozen storage shelf that can be accommodated is limited.

Application scenarios: Laboratory, clinic, etc. need to store a small number of samples or have high requirements for portability.

2. Classification by neck tube structure

        Flat mouth liquid nitrogen tank:

Advantages: Simple structure and low cost.

Disadvantages: Liquid nitrogen is prone to splashing out, which poses safety hazards.

Application scenario: It is gradually eliminated and is not recommended.

        Grooved liquid nitrogen tank:

Advantages: Liquid nitrogen is not easy to splash out, has high safety, and can effectively reduce liquid nitrogen evaporation.

Disadvantages: The cost is relatively high.

Application scenarios: Widely used in biological sample storage, medical care, scientific research and other fields.

III. Other types

        Gas phase liquid nitrogen tank: It stores gaseous nitrogen with a relatively high temperature, suitable for samples such as cells that do not have strict temperature requirements.

        Liquid phase liquid nitrogen tank: Stores liquid nitrogen with a temperature as low as -196℃. It is suitable for samples with extremely high temperature requirements such as embryos and stem cells.

        Self-suppressed liquid nitrogen tank: Built-in boosting system, which can automatically discharge liquid nitrogen for easy use.

        Transport type liquid nitrogen tank: specially designed for transportation, with good earthquake resistance and portability.

Summarize

        Different types of liquid nitrogen tanks have their own advantages and disadvantages and application scenarios. When choosing a suitable liquid nitrogen tank, you need to comprehensively consider the sample size, storage time, usage frequency, budget and other factors. I hope this article can help you better understand the types and characteristics of liquid nitrogen tanks and provide a reference for your choice.
