The thin film oxygen permeability tester (isobaric method) is a professional equipment used to test the oxygen permeability performance of thin films and packaging materials. This instrument is based on the principle of isobaric testing, and accurately measures the oxygen barrier performance of materials by simulating actual environmental conditions, providing scientific basis for material research and development, quality control, and packaging design.
The tester adopts the principle of isobaric testing, also known as Coulomb electric quantity method, and its basic working process is as follows:
Clamp the pre processed sample between the testing chambers to ensure good sealing. The test gas flows high-purity oxygen or air on one side of the film, and high-purity nitrogen on the other side. Oxygen molecules diffuse through the membrane to the nitrogen side and are carried by the flowing nitrogen gas to the sensor. The sensor accurately measures the concentration of oxygen carried in the nitrogen flow and calculates parameters such as oxygen permeability through analysis.
Application areas of thin film oxygen permeability tester (isobaric method):
Food packaging industry: Testing the oxygen permeability of various food packaging materials to ensure the quality of food preservation inside the packaging and extend the shelf life.
Pharmaceutical packaging industry: Testing the oxygen barrier performance of pharmaceutical packaging materials to ensure the stability and effectiveness of drugs.
Medical device industry: Evaluate the oxygen permeability of medical device packaging materials to ensure the safety of medical devices during transportation and storage.
Daily chemical industry: Testing the oxygen permeability of packaging materials for cosmetics, detergents, and other products to prevent product deterioration due to oxidation.
Photovoltaic electronics industry: Testing the oxygen barrier performance of packaging materials for photovoltaic materials and electronic components to ensure product quality.
The thin film oxygen permeability tester (isobaric method) complies with the following international and national standards: ISO 15105-2、ASTM D3985、ASTM F1307、ASTM F1927、GB/T 19789、JIS K7126-B、YBB 00082003
The common technological advantages of instruments are:
Multi purpose: Some models of thin film oxygen permeability testers can be configured with container testing accessories to perform dual testing modes of thin film and container, making conversion convenient and meeting different testing needs. Recommended instrument: Jinan Languang C230H Oxygen Transmittance Testing System.
High stability: Using world-class components, the instrument operates stably and reliably, with minimal external interference during the testing process.
Easy to operate: The test parameters are displayed on a large LCD screen, and the operation buttons are designed to be user-friendly. The testing process can continue during power outages.
Data Management: Supports the permanent (separated) storage of experimental data, making it easy to query and compare. Technical support can be used to calculate other gas permeation values of materials.
