30L Cryogenic Dewar Flask Liquid Nitrogen Storage Tank Wide Neck Biological Container for Laboratory Use

Nozzle design impacts operation convenience and sealing efficiency. Custom liquid nitrogen containers offer both standardized and non-standardized interface options:

1. KF Flange Nozzle: Industrial-grade sealing solution.

• Feature: International standard KF flange, metal bellows seal for vacuum sealing (leak rate ≤ 1×10⁻⁹Pa·m³/s), ideal for frequent connections (e.g., central nitrogen supply systems).

• Application: Food freezing lines, where KF flange nozzles connect quickly to freezing machines, boosting efficiency by 50% compared to traditional threaded interfaces.

• Customization: Flange size adjustable for pipe diameter compatibility, stainless steel or copper piping, with electro-polished surface to reduce nitrogen residue.

2. Flat Lid Design: Efficient for pure nitrogen storage.

• Feature: Smooth cylindrical lid without fixed sample structures, using a polyurethane neck plug for quick sealing (torque 3-5N·m).

• Application: Used for liquid nitrogen transfer or industrial supply, like food freezing tanks or laboratory nitrogen replenishment.

• Optimization: Optional lockable lid to prevent accidental nitrogen use.

Conclusion: Custom liquid nitrogen containers are not just about adjusting equipment parameters but transforming generic storage into tailored solutions. By customizing nozzle size, internal structure, and material, businesses can significantly enhance storage safety, efficiency, and cost-effectiveness. Whether for biological samples or industrial applications, customized liquid nitrogen containers are key to overcoming storage limitations and advancing low-temperature solutions.
