What are the advantages of using a gas-phase liquid nitrogen freezer to preserve stem cells?
1. The tank body is made of high-quality stainless steel, with polished surface, good load-bearing, low temperature resistance and corrosion resistance;
2. The tank mouth is designed with an offset structure, large capacity, high vacuum, and low liquid nitrogen loss;
3. Two storage methods, gas phase and liquid phase, can maintain a low temperature environment of -190° on the top of the jar;
4. Rotating trays are used internally for partitioned storage, making it easier to take out cells;
5. It has an intelligent monitoring system and can modify parameters in the settings according to needs;
6. The system can display high and low liquid levels in real time. Ultra-high and ultra-low will provide liquid level alarms, over-temperature alarms, and automatic control of fluid replenishment
