Henan Tianchi Cryogenic Machinery Equipment Manufacturing Co., Ltd.

The automated liquid nitrogen storage system is specifically designed for large-scale biological sample storage, such as stem cells, embryos, and blood samples. Tailored for biobanks and preservation centers, this system offers smart management and significantly differs from traditional liquid nitrogen containers. In addition to its large storage capacity and innovative storage mode, it provides six major advantages:

1. Temperature Monitoring:
   Real-time temperature display with ±1°C accuracy. Users can set limits for alarms, ensuring safe storage.

2. Liquid Level Monitoring & Auto Refill:
   Monitors liquid nitrogen levels with customizable high/low alarms. Auto refill ensures nitrogen is added when levels drop, stopping once the set level is reached.

3. Heat Gas Bypass:
   Ensures only low-temperature liquid nitrogen enters the tank, preventing large temperature fluctuations during refilling and maintaining sample integrity.

4. Stable Lid Design:
   Innovative lid with an offset neck minimizes nitrogen evaporation when opened, keeping the samples protected.

5. Stable Temperature Balance:
   The vapor-phase storage method, combined with a double-vacuum and multi-layer insulation, ensures stable internal temperatures (e.g., -150°C even after 48 hours of opening).

6. High Capacity, Compact Footprint:
   With capacities ranging from 350L to 1800L, the system can store hundreds of thousands of samples while minimizing space usage. The unit also includes casters for easy mobility.

This LN tank system revolutionizes storage, providing efficient, safe, and reliable sample preservation for researchers and institutions.
