In scientific research and laboratory applications, liquid nitrogen cryogenic freezers are widely used to store biological samples such as cells and tissues. By utilizing the cryogenic properties of liquid nitrogen, biological samples are frozen and stored at a low temperature below -196°C to maintain their activity and long-term preservation. The tank is made of stainless steel, which has high strength and corrosion resistance at low temperatures to ensure the quality and integrity of cell samples.

So, what are the storage advantages of liquid nitrogen cryogenic freezers?

Large diameter and large capacity: 350 liters, 750 liters, 1000 liters, 1800 liters and other capacity options are available to meet the storage needs of different users. The large diameter facilitates sample access, and the sample can be stored in a 360° rotation, with high space utilization. And the liquid nitrogen consumption is low, ensuring the stability and economy of sample storage. ‌

Intelligent management system: The system has functions such as temperature monitoring, liquid level monitoring, abnormal reminders, remote alarms, event recording and automatic rehydration, which reduces the cost of manual supervision, is safe and reliable, and is easy to manage. ‌

Compatible with both gas and liquid storage modes: Supporting both gas and liquid storage modes, samples can be stored in liquid (-196°C) or stored separately from liquid nitrogen in gas (-190°C), adapting to different sample preservation needs. ‌‌

Storage safety: Compared with conventional liquid nitrogen tanks, liquid nitrogen cryogenic freezers use gas phase storage, which can avoid the risk of cross-contamination of cell samples and bursting of cryopreservation tubes, and ensure the safety and integrity of cell samples. ‌‌‌

In addition, the design of the liquid nitrogen freezer also takes into account human factors, such as the side-mouth structure and the partitioned storage of rotating trays, making it more convenient to store and access biological samples. ‌ These features together ensure the long-term stable storage of biological samples in a deep cryogenic environment.
