Application scope: Long-term liquid nitrogen immersion (vaporization) preservation for mass biological samples such as stem cells, plasma, semen, embryos and various tissues and organs. Main features: Whole made of 304 stainless steel, surface drawn and polished; Unique vacuum technology and neck design to ensure extremely low liquid nitrogen evaporation loss rate; A vapor phase and liquid phase two storage, ensure the cervical mouth temperature - 190 ℃; Internal use of rotating tray partition storage, access biological products convenient; As part of the external rotation, manual, electric can be used; Control system adopts color touch screen LCD, which can set and modify parameters as required. Liquid nitrogen level adopts patent control system, real-time display of high and low liquid level, ultra-high and ultra-low liquid level alarm, ultra-temperature alarm, and automatic control of replenishment; Remote monitoring and central control port are reserved for remote observation and global SMS alarm. Has the function of piping hot gas by-pass leakage, the hot gas of the pipeline does not enter the tank when replenishing; As a function of cleaning fog, it is convenient to store goods visible and easy to extract; The parameter historical value, operation state and alarm are recorded by event log and graph curve. The bottom of the container is equipped with a castor with high strength and wear resistance. Can be locked for the exclusive management of biological products; Not less than five years of vacuum life. Technical parameters: Model: YDD - 400-320 Effective volume (L) : 304 Liquid nitrogen volume under tray (L) : 66 Diameter (mm) : 320 Effective internal height (mm) : 607 Outside diameter (mm) : 870 Total height (mm) : 1130 Air weight (kg) : 207 Operation height (mm) : 1130
