MPE ASR, manufactured by RayKol Group, is a highly versatile condensation receiving module that excels in precise pressure control, designed for condensation during vacuum evaporation. It offers a range of built-in pressure-decrease modes, including manual, programmed, and frequency-conversion, providing flexibility to adapt to different requirements. The system supports 20-step gradient control with an optional frequency-conversion pump for smooth pressure adjustments, specifically designed for mixed solvents with varying boiling points, its automatic condensing waste discharge system efficiently removes low-boiling solvents first, preventing interference with subsequent samples. Suitable for a wide array of scientific and industrial applications
