High-pressure phase analysis – solubility, emulsification.
This phase equilibria unit is built for the measurement and detection of phase equilibria and phase transitions by optical means.
The mixture of solute and solvent gas is agitated by the magnetic stirrer. Whenever samples are drawn from the top or the bottom connection in the cell, the directly connected counterbalance piston moves towards the centre of the cell, this keeping the pressure in the measuring cell constant even during the sampling operation. No need to add additional solvent gas, which would change mass ratio and temperature and consequently result in a disturbed equilibrium.
