Liquid nitrogen is a vital component in various industries, particularly in scientific research, medical applications, and food preservation. Proper storage of liquid nitrogen is crucial to ensure safety and efficiency. Let us understand the solutions and equipment available for liquid nitrogen storage, focusing on the types of tanks and dewars, with a special focus on products for Liquid Nitrogen storage by INOXCVA.
Understanding Liquid Nitrogen Storage
Liquid nitrogen is stored at extremely low temperatures, typically between -196°C and -210°C. The method of storage depends on the volume needed and the specific application. Two primary types of equipment are used for this purpose: liquid nitrogen storage tanks and liquid nitrogen dewars.
Liquid Nitrogen Storage Tanks
Liquid nitrogen storage tanks are designed for large-scale applications. They can hold hundreds to thousands of litres of liquid nitrogen, making them ideal for industrial or research settings where a significant volume is required.
Some of key features are as follows:
- Capacity: These tanks are optimized for long-term storage with minimal heat gain, often resulting in boil-off losses of less than 0.05% per day.
- Construction: Typically made from stainless steel, these tanks are built to withstand extreme temperatures and external conditions.
- Safety Features: Most tanks come equipped with overpressure safety valves and monitoring systems to keep track of pressure and liquid levels.
- Accessibility: Larger tanks may include ladders and access systems for easy operation.
Liquid Nitrogen Dewars
Dewars are smaller containers specifically designed for storing and transporting liquid nitrogen. They are named after James Dewar, who invented this type of container in the 19th century. Dewars come in various sizes, generally ranging from 1 to 400 litres.
The characteristics include:
- Design: Dewars typically have a cylindrical shape with a tapered neck to minimize heat intrusion. This design helps reduce evaporation.
- Insulation: Like storage tanks, dewars utilize vacuum insulation methods, often incorporating aluminium foil and glass paper layers to enhance thermal performance.
- Portability: Smaller dewars are lightweight and easy to transport, making them suitable for laboratory use or field applications.
Selecting the Right Equipment
When selecting between liquid nitrogen storage tanks and dewars, consider the following factors:
- Volume Requirements: Decide how much liquid nitrogen you need to store. For large quantities, opt for a tank; for smaller needs, a dewar may suffice.
- Application Type: Different applications may require specific features. For instance, medical labs may need high-capacity systems with security features like locking lids.
- Safety Considerations: Always prioritize safety features such as pressure relief valves and low-level alarms to prevent accidents.
INOXCVA Liquid Nitrogen Storage Tanks
- High Capacity: INOXCVA offers tanks capable of holding large volumes while ensuring low boil-off rates.

- Advanced Monitoring: Many models feature integrated monitoring systems that provide real-time data on pressure and liquid levels.
INOXCVA Liquid Nitrogen Dewars
- Versatile Sizes: INOXCVA’s dewars come in various sizes suitable for different applications, from small lab experiments to larger transport needs.
- Efficient Insulation: Their dewars employ advanced insulation techniques that significantly reduce heat transfer, thus preserving the liquid nitrogen longer.
- User-Friendly Design: Many models include features such as handles for easy transport and vented lids to prevent pressure build-up.
Best Practices for Liquid Nitrogen Storage
To ensure safe handling and storage of liquid nitrogen, adhere to these best practices:
- Use Appropriate Containers: Always store liquid nitrogen in specially designed containers like dewars or cryogenic tanks; avoid using domestic vacuum flasks.
- Ventilation is Key: Store liquid nitrogen in well-ventilated areas to prevent oxygen depletion due to evaporation.
- Regular Monitoring: Implement routine checks on the levels and pressure within your storage units to ensure they remain within safe operating limits.
Conclusion
Liquid nitrogen plays an important role across various fields by enabling cryopreservation and other critical processes. Understanding the differences between liquid nitrogen storage tanks and dewars is critical for selecting the right equipment for your needs. Cryogenic equipment providers like INOXCVA provide robust solutions that prioritise safety and efficiency in cryogenic storage.
