Cryogenic Liquid Nitrogen Storage System Biological Storage Tank-Shandong AUYAN New Energy Technology

The biological sample bank series provides users with an automatic, safe, and reliable cryogenic liquid nitrogen storage system. The tank body is made of high-quality stainless steel, with its own casters and braking devices. The ammonium chain cover is easy to open, and the large-diameter opening is convenient for sample storage. It can be stored in a liquid and gaseous state, and the microcomputer touch control system provides higher convenience and safety. For safe operation, our design ensures low liquid nitrogen consumption and a large sample storage capacity. The whole tank adopts advanced evacuation technology, adiabatic technology, and other technologies to ensure the safe storage of samples, good uniform temperature characteristics, and low liquid nitrogen consumption characteristics. When stored in the vapor phase, the temperature difference in the entire storage area exceeds 10°C, and the lowest temperature at the top of the freezer shelf can reach -190°C. The biological sample library series provides you with an intelligent storage experience, fast sample access, reliable sample protection, convenient automatic real filling of liquid nitrogen, and flexible and diverse storage capacity.

High-density storage	Compared with similar products, it occupies a small area and stores more samples, which can save space and reduce the storage cost of unit samples;
Excellent temperature uniformity	Vacuum insulated stainless steel box structure, high vacuum coverage, to ensure excellent thermal insulation and thermal insulation performance
Stable opening temperature	The innovative box cover and the excellent design of the small opening with an offset neck can greatly reduce the volatilization rate of the liquid atmosphere. Even if the cover is opened for a long time, the temperature inside the box can still be kept constant, and the temperature of the box can be maintained no higher than -150CC within 48 hours;
Advanced temperature monitoring system	The monitoring system based on a microprocessor and upper and lower double-platinum resistance temperature probes can display the highest and lowest temperature in the box in real-time with an accuracy of ±1 c. The user can set the alarm point by himself. It has the option of alarm mute;
Automatic perfusion liquid nitrogen and liquid level monitoring system	Based on the differential pressure sensor and the liquid level monitoring system, the liquid level is displayed in real-time to ensure the safety and reliability of the automatic filling process of liquid nitrogen. The 10-inch LCD screen can display parameters such as top temperature, bottom temperature, liquid level, and operating status;
Hot gas bypass	The hot gas bypass can remove the room temperature ammonia gas in the pipeline before the liquid nitrogen is injected to ensure that only ultra-low temperature liquid nitrogen is injected into the tank, which avoids the temperature fluctuation of the liquid nitrogen tank during the liquid addition process, which affects the safety of the sample and reduces the extra consumption of liquid nitrogen;
Multiple humanized designs	Stainless steel auxiliary workbench can be used for temporary placement of freezer racks to speed up sample picking and placing: the folding steps of the body reduce the operating height, which is convenient and labor-saving for picking and placing. Alternate openings in the inner swivel tray make it easy to find accidentally dropped samples.
