1000 Liter Cryogenic LN2 Tank for Preservation of Specimen

General description of the liquid nitrogen dewar containers 

The whole tank uses advanced evacuation technology, adiabatic technology and high vacuum retention technology to ensure the safe storage of specimen, good uniform temperature and the lowest liquid nitrogen consumption, When specimen in vapor storage, the entire storage area temperature differences do not exceed 10ºC, and the top of the frozen rack lowest temperature can reach -190ºC. Biobank Series provides you with the best storage experience - fast specimen access, reliable protection, convenient liquid nitrogen auto-fill and flexible storage capacity.

Advantages of Minwen's liquid nitrogen cryo dewar tanks.

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;

Vacuum insulated stainless steel structure, high vacuum coverage to ensure excellent insulation properties

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 stil be very stable; temperature couldbe not higher than -150C within 48 hours;

Microprocessor-based control system and the vertical double platinum resistance temperature probe can display real time temperature, accuracy of +1°C. 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.

The hot gas bypass can remove nitrogen which is at indoor temperature before the liquid nitrogen is fled, to ensure that only liquid nitrogen is filled into the tank and avoid temperature fluctuations in the liquid nitrogen tank during the filling process. lt would make sure the safety of the sample and also reduce the additional liquid nitrogen consumption.
