The function of liquid nitrogen biological containers is to preserve liquid nitrogen and reduce evaporation. Therefore, regardless of size, liquid nitrogen tanks should have good thermal insulation, be robust and durable, and be easy to use in order to better meet the needs of production or scientific research.

How to Choose a High-Quality Liquid Nitrogen Tank?

1. If water droplets or frost are found on the cap and top of the liquid nitrogen tank, even with liquid nitrogen inside, it indicates a quality problem and the tank should be stopped from use immediately.

2. If there are no water droplets or frost on the cap and top of the liquid nitrogen tank, touch the outer shell. If the top feels cold and the bottom feels warm, it indicates a quality problem. If the temperature is the same throughout, the tank is fine.

3. If, after opening the cap, the condensation inside the tank does not overflow but sinks, the tank is fine.

4. Listen for bubbling sounds inside the tank through the opening. Frequent bubbling indicates a quality problem; otherwise, the tank is fine.
