The liquid nitrogen tank is a container used to store liquid nitrogen. As a pressure vessel, it must comply with industry safety standards during its design, manufacture, and use. Liquid nitrogen tanks can generally be divided into two types: liquid nitrogen storage tanks and liquid nitrogen transport tanks.

Key points for using biological liquid nitrogen container:

1. Ensure proper ventilation in the work area. Liquid nitrogen is a colorless, odorless, non-toxic, and tasteless gas. However, in poorly ventilated conditions, the evaporating nitrogen will reduce the oxygen content in the room, posing a risk of suffocation. Therefore, it is essential to improve indoor ventilation and maintain fresh air.

2. Avoid damaging the neck tube. After prolonged use, frost may form on the inner wall of the neck tube. Normally, this frost and ice will not obstruct the lifting of the container, so do not scrape it with a knife. Accidentally scratching the inner wall of the neck tube may cause air leakage, loss of vacuum, and make the container difficult to repair.

3. Do not break the wick. The wick is made of special foam plastic. Sometimes, during use, the wick may become frozen in the neck and cannot be removed. In this case, do not force it to avoid breaking the wick. Use hot air to melt the ice and remove the wick.
