Determine phase equilibria up to 50 bar

VLE data for realistic process design

The FISCHER® LABODEST® VLE 602/50 is a specialized measuring system for the experimental determination of vapor-liquid equilibria (VLE) under overpressure conditions. It was developed for laboratory applications in the chemical and petrochemical industries, for process developers, equipment manufacturers, and research institutes that require thermodynamically sound data in the range up to 50 bar and 180 °C.

The system is based on the classic dynamic VLE method and is equipped with sight glasses, temperature and pressure sensors, trace heating and semi-automatic sampling. An almost adiabatic measuring cell with integrated PID control enables reproducible measurements under precisely adjustable conditions.

Ideal for designing complex separation processes such as high-pressure rectification or extractive distillation. Vacuum operation up to 25 mbar is also possible as an option.
