Advantage
High density storage
Compared with similar products, our tanks occupy a small area and store more samples, which can save space and reduce the storage cost per sample.
Excellent temperature uniformity
Vacuum insulated stainless steel box structure, high vacuum coverage, to ensure excellent thermal insulation
Stable openning temperature
Innovative box cover and neck offset small opening design can greatly reduce liquid nitrogen volatilization rate. Even if the lid is opened for a long time, the temperature inside the box can be kept stable, and the temperature in the box can not be higher than -150 ° C for 48 hours
Advanced temperature monitoring system
The monitoring system based on microprocessor and top and bottom platinum resistance temperature probes can display the highest and lowest temperature of the box in real time with an accuracy of ± 1 ° C. Users can set their own alarm point, with the option of silent alarm
Automatic liquid nitrogen infusion and liquid level monitoring system
The liquid level monitoring system based on differential pressure sensor can display the liquid level in real time to ensure the safety and reliability of the liquid nitrogen automatic perfusion process. 10 inch LCD touch screen can display top temperature, bottom temperature, liquid level height and operating status and other parameters.
Thermal bypass
The hot gas bypass can remove room temperature nitrogen from the pipeline before liquid nitrogen injection, ensuring that only ultra-low temperature liquid nitrogen is injected into the tank, avoiding temperature fluctuations in the liquid nitrogen tank during the filling process, which affects sample safety, and also reducing additional liquid nitrogen consumption.
Multi-humanized design
The stainless steel auxiliary working table can be used for temporarily placing the frozen storage shelf to speed up the sample taking and putting;The integral folding step reduces the operation height and is convenient for taking and placing;Internal rotating tray with spare opening for easy to find accidentally dropped samples.
Application
It is suitable for long-term liquid nitrogen immersion (vaporization) preservation of large quantities of biological samples such as stem cells, plasma, semen, embryos, various tissues and organs.
