GB1038 Thin Film Differential Pressure Gas Permeation Tester, Principle and Selection Recommendation Labthink

GB1038 Thin Film Differential Pressure Gas Permeation Instrument is based on the principle of differential pressure testing. By forming a constant pressure difference on both sides of the sample, gas permeates from the high pressure side to the low pressure side. It monitors the pressure changes on the low pressure side in real time and calculates the gas permeability to accurately evaluate the gas barrier performance of the material. This device is suitable for measuring parameters such as gas permeability, solubility coefficient, diffusion coefficient, etc. of plastic films, composite films, high barrier materials, and metal foils. The implementation standards include GB/T 1038, ISO 2556, ASTM D1434, etc. Jinan Languang, as a packaging and new film material barrier performance testing instrument supplier with deep research and development technology, provides customers with multiple models of differential pressure gas permeation instruments, such as VAC-V2, C106H, C130H, etc. The instruments have high-precision sensors, automated testing processes, and safety protection designs, which can meet the strict testing needs of material gas barrier performance in the fields of food packaging, pharmaceutical research and development, and new energy.
