Non-PVC Co-Extruded Large Infusion Film Oxygen Permeability Tester / Infusion Soft Bag Oxygen Transmission Rate Tester

Non-PVC Co-extruded Large Infusion Membrane Oxygen Permeability Tester / Infusion Bag Oxygen Permeability Tester The Non-PVC Co-extruded Large Infusion Membrane Oxygen Permeability Tester / Infusion Bag Oxygen Permeability Tester is based on the pressure difference testing principle. It is a professional instrument used for testing the gas permeability of film samples. It is suitable for plastic films, composite films, high barrier materials, sheets, metal foils, rubber, tire gas tightness, permeation films, etc., to measure gas permeability, solubility coefficient, diffusion coefficient, and permeation coefficient at various temperatures. Testing Principle of the Non-PVC Co-extruded Large Infusion Membrane Oxygen Permeability Tester / Infusion Bag Oxygen Permeability Tester: The pressure difference testing principle is employed, where the pre-treated sample is placed between the upper and lower test chambers and clamped. First, the low-pressure chamber (lower chamber) is subjected to vacuum treatment, and then the entire system is vacuumed. When the specified vacuum level is reached, the testing lower chamber is closed, and a certain pressure of test gas is filled into the high-pressure chamber (upper chamber), ensuring a constant adjustable pressure difference is formed on both sides of the sample. In this way, gas will permeate from the high-pressure side to the low-pressure side under the pressure gradient, and by monitoring the internal pressure of the low-pressure side, the various barrier parameters of the tested sample can be derived.
