The temperature range of a cryogenic container depends mainly on the nature of the substance being stored and the design and manufacturing materials of the container. In general, cryogenic containers can have a very wide range of temperatures, from near absolute zero to tens of degrees below zero Celsius. Here are some common cryogenic container temperature ranges:
Liquid nitrogen containers:
The boiling point of liquid nitrogen is about -196°C at standard atmospheric pressure, so the temperature range of liquid nitrogen containers is usually around -196°C. This container is used to store liquid nitrogen and is commonly used in biology, medicine, scientific research, and other fields.
Liquid Oxygen Container:
The boiling point of liquid oxygen is about -183°C at standard atmospheric pressure, so the operating temperature of the liquid oxygen container is also around this range. Liquid oxygen containers are commonly used in aerospace, medical, and industrial applications.
Liquid argon, liquid hydrogen, etc.
Containers for other cryogenic liquids will also have corresponding temperature ranges, for example, liquid argon has a boiling point of about -186°C, while liquid hydrogen has a lower boiling point of about -253°C.
ULT freezer or freezer:
These devices are typically used in laboratories or healthcare facilities to store biological samples, pharmaceuticals, or other items that require ultra-low temperature preservation. They can range in temperature from -40°C to -86°C or even lower, depending on the model and design.
Special cryogenic storage equipment:
For some special applications, such as the study of superconducting materials or the low temperature conditions of specific chemical reactions, it may be necessary to design specialized cryogenic containers with temperature ranges that can be tailored to the needs and may be as low as a few millimeters (mK) or even lower.
It is important to note that the temperature range of a cryogenic container is not only affected by the stored substance, but also by a variety of factors such as the container material, insulation design, cooling system, and ambient temperature. Therefore, when selecting a cryogenic container, in addition to the required temperature range, factors such as the performance, safety and economy of the container should also be considered.
