Nitrogen transport tanks, also known as liquid nitrogen transport dewars or cryogenic liquid nitrogen tanks, are specialized containers designed to safely transport and store liquid nitrogen. Liquid nitrogen is an extremely cold cryogenic liquid (-196°C or -321°F) used in various applications, including scientific research, medical and biotechnology industries, and agriculture.

These transport tanks are typically vacuum-insulated to minimize heat transfer and maintain the low temperatures required to keep the liquid nitrogen in its liquid state. They are constructed from materials that can withstand the extreme cold and pressure changes associated with cryogenic substances.

Nitrogen tanks play a crucial role in various industries:

1. Scientific Research: Liquid nitrogen is used in laboratories for cryopreservation, cell storage, and other experiments requiring ultra-low temperatures.
2. Medical and Biotechnology: In the medical field, liquid nitrogen is used for cryotherapy, cryopreservation of biological samples, and storing reproductive cells and tissues.
3. Agriculture: In agriculture, liquid nitrogen is utilized for quick and effective freezing of animal semen and embryos for artificial insemination and animal breeding programs.
4. Industrial Applications: In some industrial processes, liquid nitrogen is used for cooling, cryogenic grinding, and inerting hazardous materials.
