Liquid Nitrogen Dewar Tanks: Superior Cryogenic Storage & Transportation Solutions

Liquid Nitrogen Dewar Tanks: Superior Cryogenic Storage & Transportation Solutions

Product Description:

In the relentless pursuit of technological advancement, humankind has continuously strived to overcome the challenges posed by extreme temperature environments. A pivotal breakthrough came with the mastery of highly vacuumed, multi-layer insulation technology. This innovation effectively mitigated heat leakage caused by convection, conduction, and radiation, issues that plagued earlier cryogenic storage methods dating back to 1898 when Sir James Dewar pioneered the vacuum flask.

Leveraging state-of-the-art highly vacuumed multi-circle insulation technology, we manufacture a comprehensive line of biological liquid nitrogen Dewar tanks. Our tanks are engineered to provide exceptional low-temperature insulation, minimizing nitrogen evaporation and maximizing holding times. This makes them indispensable across a wide spectrum of industries, including:

• Agriculture: Cryopreservation of animal semen for artificial insemination programs, preserving genetic diversity and improving livestock quality.

• Medical Treatment: Storage of vaccines, blood samples, tissues, and organs for transplants and research, ensuring their long-term viability.

• Scientific Research: Preservation of biological samples, including cell cultures, bacteria, viruses, and fungi, vital for ongoing scientific discovery.

• Machine Manufacture: Cryogenic treatment of metals to enhance their mechanical properties, and precision assembly of components requiring extreme dimensional stability.

• **Food Industry: ** Flash freezing of food products for optimal preservation of flavor, texture, and nutritional value.

• **Pharmaceuticals: ** Safe and stable storage of temperature-sensitive drugs and biologics.

In these diverse fields, liquid nitrogen serves as an invaluable cryogen, enabling the storage of animal semen, vaccines, mushroom spores, and other sensitive biological materials. It also facilitates the cryogenic treatment of metals and the precise assembly of components requiring exceptional dimensional control.

Key Applications:

1. Animal Semen Preservation: Our Dewar tanks play a critical role in preserving the semen of superior livestock breeds, including cattle and sheep, as well as rare and endangered species like pandas. They enable long-distance transport and storage of genetic material, contributing to improved breeding programs and conservation efforts.

2. Biological Sample Preservation: Vaccines, bacteria, viruses, cell cultures, and human and animal tissues and organs can be safely stored in liquid nitrogen for extended periods. This allows for the long-term preservation of viability, enabling researchers and medical professionals to thaw and utilize these samples as needed.

3. Deep Cryogenic Metal Treatment: Exposing metals to extremely low temperatures achievable with liquid nitrogen results in significant microstructural changes. This process enhances hardness, strength, wear resistance, and overall durability, extending the lifespan of critical components and improving their performance.

4. Precision Parts Cryogenic Assembly: The use of liquid nitrogen in cryogenic assembly processes improves the quality and overall performance of equipment. By shrinking components to extremely precise dimensions, liquid nitrogen enables tight fits and enhanced structural integrity, leading to improved reliability and longevity.

Quality and Standards:

Our liquid nitrogen Dewar tanks are designed and manufactured to meet or exceed industry standards. Currently, the relevant national standard is GB/T5458-1997 "Biological Liquid Nitrogen Containers." This standard, established by the Department of Agriculture, drafted by the National Quality Supervision and Inspection Center of Cryogenic Vessels, and implemented by the National Technical Supervision Bureau, ensures the safety and reliability of cryogenic storage solutions.

Since our inception, we have been committed to continuous improvement and innovation. By leveraging advanced technologies and rigorous quality control measures, we have consistently enhanced the performance and reliability of our products.

Compared to national standards, our biological liquid nitrogen containers demonstrate substantial improvements in key performance parameters, including technical quality indicators and static liquid nitrogen retention period. Moreover, our quality indicators are approaching those of similar products manufactured in Europe and the United States, reflecting our dedication to providing world-class cryogenic storage solutions.
