Low temperature storage of biological samples

The refrigeration system adopts a single compressor refrigeration and a two-stage cascade refrigeration method. And it is equipped with multiple protection functions to ensure the safe operation of the equipment. Through the refrigeration of the unit itself, the liquid low-temperature refrigerant is sent to the end evaporator for cooling, creating a low-temperature environment that meets the requirements of the process conditions.

Adopting single machine self stacking technology, it occupies a small footprint and can integrate two sets of systems for switching and use
Constant temperature range:
-60℃±1℃
-80℃±1℃
-120℃±1℃
