Currently, the technology of using liquid nitrogen to freeze animal semen for artificial insemination has been widely used in livestock production.

Because the temperature of liquid nitrogen is -196°C, and its boiling point is low, it is easy to volatilize and is difficult to store. Non-special containers - liquid nitrogen tanks cannot be stored well, let alone serve as a refrigerant for freezing semen. Therefore, it is difficult to use Liquid nitrogen containers for storing semen have become one of the essential equipment in animal husbandry.

In animal husbandry applications, in addition to preserving animal semen as mentioned above, liquid nitrogen tanks are also mainly used for freezing embryos, preserving veterinary drugs, vaccines, etc. Of course, the main focus is on the preservation and transportation of sperm from male animals such as pigs and cattle.

At this point, I have to mention that as a low-temperature container for storing animal semen, the capacity selection of livestock liquid nitrogen tanks cannot be ignored. Appropriate capacity can help breeders effectively and quickly preserve animal semen.

So how to choose?

Look at the specific usage scenario!

If you go out to collect semen, the quantity is generally not very large, but when you go into mountainous areas, you often use portable small-diameter liquid nitrogen tanks, mostly with a capacity of 6 liters and 10 liters. Although there are also smaller ones of 3 liters, they are static liquids. The storage time of nitrogen is short, and under such dynamic conditions, liquid nitrogen will evaporate faster, so its use is not recommended;

There is also a 16-liter capacity option, which is a small vehicle-mounted tank with better stability and longer storage time of liquid nitrogen.

For long-term storage of frozen semen, you can choose a 30-liter or 35-liter liquid nitrogen tank with a diameter of 125mm. It has a static storage time of about 3 months. It is very suitable for long-term storage at home. Frequent replenishment of liquid nitrogen is not required. The quantity is between 5,000-20,000, which can meet the needs of most frozen semen users.

To sum up, you can choose 6 liters, 10 liters, or 16 liters of liquid nitrogen tanks with a diameter of 50mm for out-of-town semen collection; you can choose 30, 35 liters, and 125mm diameter tanks for long-term storage. Of course, the quantity of frozen semen stored cannot be ignored!
