Liquid Nitrogen Cryostat – Wide Temperature Range Cryogenic Cooling System
Dexing Magnet's liquid nitrogen cryostat is engineered using the steady-state bubble principle, providing a highly efficient and stable cryogenic solution for various scientific and laboratory applications. This advanced system features a liquid nitrogen reservoir that regulates the gas-liquid interface by adjusting the cone-shaped gas plug. The result is minimized heat leakage and excellent thermal stability.
By fine-tuning the heating power through a precision temperature controller, the sample holder's temperature can be rapidly adjusted within a broad range of 65K to 800K, then accurately stabilized at the desired setpoint.

Comparison with closed cycle cryostat：
Refrigeration method: Liquid nitrogen cryostat uses liquid nitrogen as the cooling medium, while closed cycle cryostat uses compressors or other refrigeration devices.
Temperature control range: The temperature control range of liquid nitrogen cryostat is lower, up to -196 ° C, while the temperature control range of closed cycle cryostat is generally -40 ° C ~200 ° C.
Application: Liquid nitrogen cryostat is mainly used in the field of ultra-low temperature, and closed cycle cryostat has a wider application range.
Cost: Liquid nitrogen cryostat has a high cost performance in terms of performance, stability and price, which saves costs for users.
