Article source:What are the precautions for liquid nitrogen tanks?  Hits:26  Release time:2024-03-19

  Liquid nitrogen tank is a common instrument and equipment commonly used in laboratories. During use, it is necessary to strictly follow the instructions, and there are also some precautions that need to be noted. Let's take a look at some precautions for liquid nitrogen tanks:

  1. The liquid nitrogen tank can only be used to fill liquid nitrogen and cannot be filled with other low-temperature media, otherwise it may react with some flammable substances on the structure of the container and cause an explosion.

  The storage environment for liquid nitrogen tanks should be in a cool and dry indoor environment, and ventilation should also be maintained.

  3. When operating the liquid nitrogen tank, it is necessary to take protective measures, as the temperature of liquid nitrogen is extremely low and can reach -196 ℃. Common protective measures include cotton gloves, wearing leather, and so on.

  When filling with liquid nitrogen, the speed must not be too fast. First, inject a small amount until the inner container gradually cools down, and then accelerate the speed after the boiling phenomenon of liquid nitrogen weakens. Also, do not fill it too full, and the height of the liquid level should not come into contact with the fiberglass neck tube.

  5. After the container is contaminated, it can be cleaned with clean water. First, drain the liquid nitrogen and restore it to normal temperature before cleaning. Also, be careful not to fill too much water during cleaning to avoid damaging the container when pouring sewage again.

  The above are some precautions about liquid nitrogen tanks that everyone must pay attention to. If you want to learn more about relevant content, you can visit the official website of Haisiyuan at www.hsy515.cn!
