Gas Permeation Testing Equipment for Precision Material Analysis

DESCRIPTION / TECHNICAL SPECIFICATIONS

Introducing an essential instrument for quality control, a gas permeation tester designed to measure the gas transmission rate (GTR) of packaging material. This instrument is widely used in crucial industry sectors such as food, pharmaceuticals, and cosmetics. Its application covers testing on various flexible packaging materials, including plastic film, barrier materials, sheets, metal aluminum, and PVC. The instrument is also a mainstay for colleges, universities, and quality institutions for testing the permeation of gases like O2, CO2, and N2. Its reliability is backed by full compliance with leading international standards, including ISO 2556-2001, ISO15105-1, and ASTM D1434-82 (2003).

The working principle of this device is based on the accurate differential pressure method. A prepared sample is placed between the upper and lower chambers and then clamped securely. The entire system is then put under vacuum. Subsequently, a test gas is introduced into the upper chamber to create a constant pressure, thereby forming a pressure differential between the two sides of the sample. Under these conditions, the gas will permeate from the high-pressure side to the low-pressure side, and by monitoring the pressure changes in the lower chamber, various testing parameters can be precisely obtained.

Engineered for efficiency and ease of use, this instrument features an automatic test function with a user-friendly, non-maintenance design. It offers two test modes for high and low barriers, providing a wide measurement range with high precision. Temperature control is also automated, with the system able to increase and decrease the temperature as needed without any special requirements for the surrounding environment. All testing parameters are displayed in real-time, giving the operator complete process monitoring.

The reliability and accuracy of the test results are guaranteed by the use of superior components that yield high stability. With a measuring range from 0.02 to 5000 cm³/m².day.0.1Mpa, expandable to 50000, this tool is highly flexible for various material types. Its measuring accuracy reaches 0.01cm³/m².day.0.1Mpa with a temperature precision of ±0.1°C. To ensure operational safety, the instrument is equipped with a multi-level security protection design. Its quality recognition is proven by CE, UL, and FCC certifications.

As a global solution, this instrument provides versatile language support for ease of operation in different countries. By combining full automation, high precision, and long-term reliability, this gas permeation tester is a smart investment for any laboratory focused on product quality assurance. It is the definitive tool for ensuring packaging integrity, extending product shelf life, and meeting the strictest international quality standards.
