The ST500 Atmosphere Purification Device is a new type of experimental processing equipment that integrates high-temperature degassing, cryogenic condensation, liquid nitrogen freezing, vacuum pumping and monitoring, built-in compressor refrigeration, and control units into one system. It is designed based on laboratory experimental processing standards and operating procedures.

Applicable to solid media such as molecular sieves and silica gel; the two-stage condenser and freezer significantly improve the efficiency of water vapor collection, preventing pipeline blockages; equipped with a built-in freezing cold source, the freezing temperature is stable and adjustable, ensuring convenient operation; the desorption temperature can reach 500°C, with a vacuum level ≤-97kPa, achieving near-complete water vapor desorption and effectively avoiding memory effects.
