Vapor Pressure Analyser

Vapor Pressure Analyser

The Vapor Pressure Analyzer (VPA) measures the vapor pressures of solids, liquids and oils using the Knudsen effusion method.

The vapor pressure defines the amount of vapor phase material that exists in equilibrium with the original material. All materials enter the vapor phase by sublimation (solid – gas) or evaporation (liquid – gas).

The vapor pressure of a material at thermodynamic equilibrium is a fundamental property of the material and is only a function of temperature.

  • Experimental temperature  20°C - 85°C
  • Sample pre-heater up to 400°C
  • Rotary pump Vacuum pressure 1 x10-3Torr.
