Features:

• Automated Control

A recent extension of the classic BET technique now allows for the automated, volumetric characterization of adsorption of the vapor of a liquid as a function of increasing or decreasing partial pressures of the liquid vapor. Liquids used include water and other organic liquids such as benzene, hexane, and acetone. Specific applications for the Liquisorb Sorptometer include evaluating how quickly building materials will deteriorate based on their adsorption properties, properties of nonwovens such as moisture vapor transmission and adsorption, and properties of ceramics, including repulsion and adsorption.
