HPVC 350-vv

The High Pressure Phase Equilibrium unit is designed for determining phase equilibrium  and PVT – analysis at elevated pressure, e.g. in presence of compressed carbon dioxide (CO₂) according to the synthetic or analytic method. By use of a view chamber, formation of different fluid or solid phases may be detected, such as precipitates or gas bubbles in a liquid. Solid samples may be inserted into the view chamber by opening the windows. Liquids are fed to the system by a syringe pump (manual or automatic). One of the continuous fluid phases, usually a gas phase, may be recirculated for obtaining an intensive phase contact. The gas phase may be passed through a six port valve for gas analysis. A sample of the liquid phase may be retrieved directly from the view cell while maintaining the pressure constant with a hand piston or automatic syringe pump.

HPVC 500 vv

This unit is designed for determining phase equilibrium or reactions at elevated pressure, e.g. in presence of compressed gases, according to the synthetic or analytic method. By use of the view chamber, different fluid or solid phases may be observed, such as formation of precipitates or gas bubbles in a liquid. Solid samples may be fed to the view chamber by opening one of the windows. Liquids are fed to the system e.g. by a syringe pump.
A magnetically coupled stirrer assures mixing of the fluid phases in order to intensify phase contact. A sample of the coexisting fluid phases may be retrieved directly from the view cell while maintaining the pressure constant with
a manually driven piston.
