Equilibrium Sapphire Cell apparatus for CO2 rich mixtures studies

The Equilibrium Sapphire Cell apparatus is designed for studying low-temperature vapor-liquid equilibrium (VLE), specifically tailored for CO2-rich mixtures. This equipment features a stirred sapphire tubular cell mounted between two Hastelloy C276 or Titanium flanges, making it ideal for precise phase behavior studies under controlled pressure and temperature conditions.
