Purity 99.999%: Liquid Nitrogen with purity 99.999% is used in semiconductor wafer fabrication, where ultra-high purity ensures defect-free electronic components. Boiling Point -196°C: Liquid Nitrogen with a boiling point of -196°C is used in cryogenic preservation of biological samples, where stable ultra-low temperatures maintain cell viability. Low Viscosity: Liquid Nitrogen characterized by low viscosity is used in rapid food freezing processes, where quick heat transfer preserves texture and nutrients. High Thermal Stability: Liquid Nitrogen exhibiting high thermal stability is used in cryogenic grinding of polymers, where controlled cooling improves particle size uniformity. Odorless and Inert Gas: Liquid Nitrogen as an odorless and inert gas is used in inerting storage tanks, where oxygen displacement prevents oxidation and fire risks. Stable Storage Temperature -210°C: Liquid Nitrogen with a stable storage temperature of -210°C is used in superconducting magnet cooling, where precise temperature control enhances magnetic performance. Low Impurity Content: Liquid Nitrogen with low impurity content is used in pharmaceutical production, where contamination risks are minimized. Rapid Expansion Coefficient: Liquid Nitrogen with a rapid expansion coefficient is used in shrink fitting of metal parts, where thermal contraction allows for seamless assembly. |
| Packing | A double-walled, insulated metal dewar containing 10 liters of liquid nitrogen, featuring safety labeling, secure handles, and a pressure-relief valve. |
| Container Loading (20′ FCL) | 20′ FCL container loaded with Liquid Nitrogen in cryogenic tanks, ensuring secure, insulated transport to maintain ultra-low temperatures. |
| Shipping | Liquid nitrogen must be shipped in well-insulated, approved cryogenic containers (dewars or pressure vessels) designed for extremely low temperatures. The containers must be securely sealed and properly labeled according to hazardous materials regulations, indicating “Non-Flammable Gas” (UN1977). Proper ventilation during transport is essential to prevent pressure buildup and ensure safety. |
| Storage | Liquid nitrogen is stored in specialized, insulated containers known as Dewar flasks or cryogenic tanks. These vessels are designed to minimize heat transfer, preventing rapid vaporization. Storage areas should be well-ventilated to avoid asphyxiation hazards from nitrogen gas buildup. Containers must be clearly labeled, kept upright, and regularly checked for pressure buildup to ensure safe handling and storage. |
| Shelf Life | Liquid nitrogen does not have a shelf life; it slowly evaporates over time and must be kept in insulated containers. |
