Gas permeability tester with Temperatuer and Humidity generator

Product catalog summary

Overview: The document provides detailed information about the VAC-V2 Gas Permeability Tester by Labthink Instruments Co., Ltd. This instrument is designed for measuring the gas transmission rate, solubility coefficient, diffusion coefficient, and permeability coefficient of various materials such as plastic films, composite films, and aluminum foils.

Professional Technology:

The instrument can measure multiple properties in a single operation.
It allows testing of three distinct specimens simultaneously with independent results.
Features wide-range temperature and humidity control for diverse testing conditions.
Offers proportional and standard test modes, with extendable test ranges for high permeability materials.
Capable of testing under extreme conditions using data fitting functions.
Customizable for testing poisonous, inflammable, and explosive gases.
Controlled by a computer for automatic testing processes.
Includes a reference film for fast calibration and accurate data.
Equipped with an RS232 port for data transfer and supports Lystem™ Lab Data Sharing System.

Test Principle: The instrument uses a differential pressure method where a specimen is placed in a gas diffusion cell, creating a sealed barrier between two chambers. Gas is introduced into the higher-pressure chamber, and its permeability is measured by monitoring pressure changes in the lower chamber.

Standards Compliance: The instrument conforms to ISO 15105-1, ISO 2556, GB/T 1038-2000, ASTM D1434, JIS K7126-1, and YBB 00082003 standards.

Applications:

Basic applications include testing films, sheeting, and various gases.
Extended applications cover inflammable and explosive gases, biodegradable films, aerospace materials, paper and paper board, paint films, glass fiber cloth and paper, cosmetic tubes, and rubber sheeting.

Technical Specifications:

Film test range: 0.05 ~ 50,000 cm³/m²·24h·0.1MPa (standard volume).
Number of specimens: 3 with independent results.
Temperature range: 5°C ~ 95°C with ±0.1°C accuracy.
Humidity range: 0%RH to 100%RH with ±1%RH accuracy.
Specimen size: Φ97 mm with a test area of 38.48 cm².
Test gases include O2, N2, and CO2.
Instrument size: 760 mm(L) x 575 mm(W) x 450 mm(H), weight: 88 kg.

Configurations: The standard configuration includes the main body, professional software, sample cutter, vacuum grease, filter paper, and vacuum pump. Optional parts include blades, vacuum grease, pump oil, and filter paper.

Note: The gas supply port requires Φ6 mm PU Tubing, and customers must prepare the gas supply.

PERME® VAC-V2 Gas Permeability Tester Yarina Gao [email protected] VAC-V2 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, and aluminum foils. Professional Technology            Gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient of the specimen could be obtained at one operation 3 distinct or equivalent specimens could be tested individually with independent test results at one operation Wide range and high precision temperature and humidity control to meet various test conditions The instrument comes with two test modes: proportional mode and standard mode Test range could be extended based on user requirements to test the materials with high permeability Test results could be easily obtained even at extreme conditions by data fitting function, which could fit any temperature 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 Standard RS232 port for convenient data transfer 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 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 Applications This test instrument is applicable to the determination of gas permeability of: Including plastic films, plastic composite films, paper-plastic Basic Applications aluminum foil, aluminum foil composite films, and many others Sheeting composite films, geomembranes, coextruded films, aluminized films, Various Gases Including engineering plastics, rubber, and building materials, e.g. PP, PVC, and PVDC Test the permeability of various types of gases, e.g. O 2, CO2, N2, Air Labthink Instruments Co., Ltd.144 Wuyingshan Road, Jinan, P.R.China (250031) Phone: +86-531-85068566 FAX: +86-531-85812140
