Phase Equilibria Apparatus Brochure

Phase Equilibria ApparatusPhase equilibria cell with pressure-balanced piston. 4Phase equilibria unit with stirred optical cell and pressure-balanced piston for isobaric sampling. System includes also pressure generation, pressure and temperature control, colour camera with endoscope and cold-light source. Unit is in operation in a pharmaceutical company (Belgium).Standard Design OptionsMax. operating pressure 500 bar 700, 1000 barMax. operating temperature 80°C 120, 150, 200°CEquilibria cell capacity 25 ml 50 mlSystem for fast determination of solubility data and for the observation of phase behaviour at high-pressure conditions, as base for supercritical fluid extraction processes.Advantagesn Pressure-balanced optical cell allows to take samples without disturbing the equilibrium conditionsn Fast achievement of phase equilibria due to intense stirringn Sapphire windows for the observation of the phase behaviour in function of pressure and temperatureFeaturesn Stirred phase equilibria cell with counterbalance pistonn Camera system with endoscope and cold-light source to represent the inside of the cell on a monitorn Sampling valves for the upper and the lower phaseOptionsn External recirculation of liquid and gas phase with high-pressure gear pumpn Larger cell capacitiesn Sapphire windows up to optical width of Ø 28 mmHigh-pressure gear pump for option «External recirculation» of upper and lower phase. It allows faster mixing of the phases or pulsation-free feeding to an injection loop for online concen- tration measurements (SFP, HPLC, etc.).
