The Short Path Evaporator integrates the features and advantages of thin film or wiped film evaporators but adds internal condensing for applications where the operating pressures must be between 0.5 mmHg and 0.001 mmHg or less.

SPE's are widely used in fine and specialty chemicals for thermal separation of intermediates, concentration of high value products, and molecular distillation under fine vacuum conditions. Their key features make them uniquely suitable for gentle evaporation and concentration of heat sensitive products at low pressures and temperatures.
