The ST500 Atmosphere Analysis Device is a new type of experimental processing equipment that integrates high-temperature digestion, zero-degree freezing, liquid nitrogen freezing, negative pressure trapping and monitoring, built-in compressor refrigeration, and control units into one system. It is designed according to laboratory standards and operating procedures.

Applicable to solid media such as molecular sieves and silica gel; the two-stage freezing and cryogenic trap significantly improves the efficiency of water vapor collection, preventing pipeline blockages; equipped with a built-in freezing cold source, the freezing temperature is stable and adjustable for convenient use; the desorption temperature can reach 500°C, with a negative pressure of ≤-97kPa, ensuring nearly complete water vapor desorption and effectively avoiding memory effects.
