Gas Permeability Tester for Flexible packaging Materials

Product catalog summary

Overview: The VAC-V1 Gas Permeability Tester by Labthink Instruments Co., Ltd. is designed for determining the gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of various materials such as plastic films, composite films, and more. It operates on the differential pressure method.

Professional Technology:

Simultaneous measurement of multiple coefficients in one operation.
Two test modes: proportional and standard.
Extended test range for high permeability materials.
High precision temperature control for varied test conditions.
Data fitting function for extreme conditions.
Capability to test poisonous, inflammable, and explosive gases with customization.
Computer-controlled automatic test process.
Fast calibration with reference film and data sharing via Lystem™ Lab Data Sharing System.

Test Principle: The specimen is mounted in a gas diffusion cell, creating a sealed barrier between two chambers. A pressure difference is established, and gas permeates through the specimen. Monitoring pressure changes in the lower chamber allows for the determination of gas permeability and barrier properties.

Standards: Conforms to ISO 15105-1, ISO 2556, GB/T1038-2000, ASTM D1434, JIS K7126-1, YBB 00082003.

Applications:

Basic Applications: Films, sheeting, and various composite materials.
Extended Applications: Various gases, inflammable and explosive gases, biodegradable films, aerospace materials, paper and paper board, paint films, glass fiber cloth and paper, cosmetic tubes, and rubber sheeting.

Gas Permeability Tester for Flexible packaging Materials-1

I PERME® VAC-VI Gas Permeability Tester VAC-V1 is based on the differential pressure method, and is professionally applicable to the determination of gas transmission rate as well as solubility coefficient, diffusion coefficient and permeability coefficient of plastic films, composite films, high barrier materials, sheeting, metal foils, rubber, tires, and permeable membranes. Professional Technology • Gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of the specimen could be obtained at one operation • The instrument comes with two test modes: proportional mode and standard mode • Test range could be extended based on user requirements to test materials with high permeability • High precision temperature control to meet different test conditions • Test results could be easily obtained even at extreme condition by data fitting function, which could fit any • The instrument could be used to test poisonous, inflammable, and explosive gases (customization required) • The instrument is controlled by a computer and test process is automatic • Reference film for fast calibration to ensure accurate and universal test data • Fast-access calibration port for temperature and humidity, and standard RS232 port for convenient calibration • Support 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 the 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: This test instrument is applicable to the determination of gas permeability of: Including plastic films, plastic composite films, paper-plastic Films composite films, geomembranes, coextruded films, aluminized films, aluminum foil, aluminum foil composite films, and many others Including engineering plastics, rubber, and building materials, e.g. PP, Labthink Instruments Co., Ltd.144 Wuyingshan Road, Jinan, P.R.China (250031) Phone: +86-531-85068566 FAX: +86-531-85812140
