VAC-VBS-1

PERME® VAC-VBS Gas Permeability Tester VAC-VBS is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate of films, sheeting, high barrier materials and aluminum foils. Professional Technology • The GTRs of various films for distinct gases are testable • Tests 3 equivalent specimens at one operation and exports test results in average value • Equipped with temperature control device(optional parts) to meet various test conditions • The instrument comes with two test modes: proportional mode and standard mode • The system is controlled by computer and test process is automatic • Reference film for fast calibration to ensure accurate and universal test data • Equipped with RS232 port for convenient data transfer • Supports Lystem™ Lab Data Sharing System for uniform management of test results and test reports Test Principle The pre-conditioned specimen is mounted in the gas diffusion cell as to form a sealed barrier between two chambers. The lower-pressure chamber is firstly evacuated, followed by the evacuation of the entire cell. A flow of gas is thereafter introduced into the evacuated higher-pressure chamber and a constant pressure difference is generated between two chambers. The gas permeates through the specimen from the higher pressure side into the lower side. The gas permeability and other barrier properties of the specimen can be obtained by monitoring the pressure changes in the lower chamber. This test instrument conforms to the following standards: ISO 15105-1, ISO 2556, GB/T 1038-2000, ASTM D1434, JIS K7126-1, YBB 00082003 This test instrument is applicable to the determination of gas permeability of: Basic Applications Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others_ Including engineering plastics, rubber, and building materials, e.g. PP, PVC and PVDC Test the permeability of various types of gases, e.g. O2, CO2, N2, Air Various Gases and He Extended Inflammable, . . Test the permeability of inflammable and explosive gases Applications Explosive Gases Test gas permeability of various sorts of biodegradable films, e.g. Biodegradable Films _starch-based biodegradable bags_ Labthink Instruments Co., Ltd. 144 Wuyingshan Road, Jinan, P.R.China (250031) Phone: +86-531-85068566 FAX: +86-531-85062108 Labthink International, Inc. 200 River's Edge Drive, Medford, MA, 02155, U.S.A.
