* Large caliber: Extra-large caliber, including tank calibers of 317, 440, 465, and 635,convenient for sample storage and easy to use.

* Optional Vapor Phase & Liquid Phase: The vapor phase or liquid phase storage method can be freely selected, and the storage area temperature is constant and close to the liquid nitrogen temperature when the vapor phase is used.

* Low Energy Consumption & High Cooling Retention: High vacuum insulation,wrapped multi-layer insulation technology, uniform and stable insulation design, can achieve low energy consumption of the container, and keep the port temperature stable below -190℃.

* Intelligent Monitoring: Optional intelligent monitoring system enables high-precision temperature and liquid level monitoring for LN2 tanks, and provides local and remote warnings via SMS, phone calls, WeChat, etc. to ensure the safety of samples.

*Intelligent Fluid Replenishment:Through precise monitoring of internal temperature and liquid level in LN2 tanks,complemented by an automated refill system, intelligent management of liquid nitrogen replenishment is achieved.
