Product Advantages

1. Big storage capacity
   Compared with similar products, our products need less space and could store more samples; save space and also reduce the cost.
2. Excellent temperature uniformity
   Vacuum insulated stainless steel structure, high vacuum coverage to ensure excellent insulation properties.
3. Stable temperature while lid is open
   Innovative lid and excellent small neck openings design can greatly reduce the liquid nitrogen evaporation rate. Even keep the lid open for a long time, the temperature inside the tank can still be very stable, temperature could be not higher than -150℃ within 48 hours.
4. Advanced temperature monitoring system
   Microprocessor-based control system and the vertical double platinum resistance temperature probe can display real time temperature, accuracy of ±1℃. The user can set their own alarm temperature value, with alarm mute option.
5. Automatic filling liquid nitrogen and liquid level monitoring system
   Based on the differential pressure sensor, level monitoring system could display real-time liquid level, to ensure that the liquid nitrogen automatic filling process safe and reliable. 10-inch LCD touch screen display: temperature of the top, bottom temperature, liquid level, and operating status etc.
6. Hot gas bypass
   The hot gas bypass can remove nitrogen which is at indoor temperature before the liquid nitrogen is filled, to ensure that only liquid nitrogen is filled into the tank and avoid temperature fluctuations in the liquid nitrogen tank during the filling process. It would make sure the safety of the sample and also reduce the additional liquid nitrogen consumption.
7. Humanization design
   Stainless steel auxiliary table, can be used for temporary placement for the racks to speed up the sample picking and placing; folding steps reduce the height of the operation platform; spare opening on the internal tray for easy to find inadvertently dropped samples.
