<\/span> The liquid nitrogen tank creates an extremely low internal temperature environment through the evaporation and heat absorption principle of liquid nitrogen. Liquid nitrogen acts as a coolant and absorbs heat when evaporating inside the tank, causing the temperature inside the tank to drop rapidly and maintain it at a very low level. This low-temperature environment can effectively extend the shelf life of samples and maintain their original biological activity or food flavor.<\/span><\/p>\n 1. Biomedicine: In the field of biomedicine, liquid nitrogen tanks are often used to preserve biological samples, such as blood, cells, tissues, etc. A low-temperature environment can slow down the metabolic process of biological samples, prevent cell death, and provide a reliable source of samples for subsequent experimental research.<\/span><\/p>\n 2. Food industry: In the food industry, liquid nitrogen tanks are used for long-term preservation and freezing processing of food. For example, liquid nitrogen rapid freezing technology can maintain the nutritional content and taste of food and extend the shelf life of food.<\/span><\/p>\n 3. Agricultural scientific research: In agricultural scientific research, liquid nitrogen tanks are often used to preserve agricultural biological resources such as seeds and strains. Through low-temperature preservation, the genetic stability and biological activity of resources can be maintained, providing abundant germplasm resources for agricultural scientific research.<\/span><\/p>\n![\"liquid](\"https:\/\/img01.71360.com\/w3\/og8ox4\/20240219\/e2014ca3195a2be766c0b8c67b98f674.webp\" "\\"liquid")
