Diffusional Permeability Analyzer is a Laboratory Instrument used to measure the Permeability of materials to gases, vapors, or small molecules through a Diffusion Process. It helps to determine how easily specific gases or molecules can pass through a material over time, providing crucial data for applications such as packaging, membrane development, and the study of gas transport in various materials. It is a valuable tool for understanding and optimizing the performance of materials in Gas Separation, Filtration, and protective barrier applications.
