Ｋｒｙｏ - 10程序降温仪是由微电脑控制、采用液态氮作致冷剂的一种低温环境下的高精度温控仪。冷冻室温度可低至 - 160℃、并能按照用户设置的控制程序以各种速率升降温或保持在某一温度 ,因而 ,广泛地应用于骨髓、皮肤的移植和器官的低温保存。一、系统结构与工作原理Ｋｒｙ The Kryo - 10 Program Cooler is a high precision temperature controller in a low temperature environment controlled by a microcomputer and using liquid nitrogen as the refrigerant. Freezer temperature can be as low as -160°C, and it can be used to increase or decrease the temperature at various rates or maintain a certain temperature according to the user’s control program. Therefore, it is widely used in bone marrow, skin transplantation and organ cryopreservation. First, the system structure and working principle Kry
