SURFACE MEASUREMENT SYSTEMS VAPOR PRESSURE ANALYZER

DVS - VPA

 

Brand: SURFACE MEASUREMENT SYSTEMS
Product: VAPOR PRESSURE ANALYZER

Description:

The Vapor Pressure Analyzer or VPA measures the vapor pressures of solids, liquids and oils using the Knudsen effusion method.
The vapor pressure is an important material physical property that 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.
The rate of mass loss through the orifice is measured by the Surface Measurement Systems UltraBalance.
The amount of sample which can be loaded varies between 1 and 100 mg and the experimental temperature range is between 20°C and 400°C.
