ASTM F1307-02 standard for oxygen transmission rate states an alternative test method using a coulometric sensor. This method involves exposing the outside of a package to a known oxygen concentration while purging the inside with nitrogen. By applying different sealing methods, various types of package can be tested (bottles, pouches, etc.).

Labthink C230H Oxygen Transmission Rate Tester is designed and manufactured based on the coulometric sensor method. This instrument offers dual testing capabilities for films and packages. The unique fixing structure allows for strong sealing around container openings.

As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website https://en.labthink.com to learn more!
