Labthink Oxygen Permeability Test Equipment for Contact Lenses

Product catalog summary

Overview: The LABTHINK VAC-V2 Gas Permeability Tester is designed for precise and reliable measurement of gas permeation rates in various materials such as films, sheeting, and foils. It is capable of testing the gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient.

Applications: The tester is suitable for a wide range of materials including films, sheeting, biodegradable films, aerospace materials, paper, paint films, glass fiber cloth, soft tube materials for cosmetics, and rubber sheeting. It can also handle various gases, including inflammable and explosive ones.

Features: The instrument allows testing of three specimens simultaneously, with independent results. It offers high precision temperature and humidity control, two test modes (proportional and non-proportional), and can be customized for testing poisonous, inflammable, and explosive gases. The device is computer-controlled, ensuring automatic test processes, and supports data sharing through the Lystem™ Lab Data Sharing System.

Technical Specifications: The tester has a test range of 0.1 to 100,000 cm³/m²·24h·0.1MPa, can handle three specimens at a time, and has a vacuum resolution of 0.1Pa. The test chamber maintains a vacuum degree of less than 20Pa, and the specimen size is Φ80 mm with a test area of 28.27cm². It supports gases like O2, N2, and CO2, with a test pressure range of -0.1MPa to +0.1MPa and a gas supply pressure of 0.4MPa to 0.6MPa. The instrument dimensions are 670mm x 490mm x 350mm, and it weighs 57 kg.
