The technical characteristics of the oxygen permeability tester for pharmaceutical packaging materials are mainly reflected in the following aspects:

Principle of Oxygen Transmittance Tester for Drug Packaging Materials

The processed sample is clamped onto the testing chamber, with oxygen or air flowing on one side of the membrane and high-purity nitrogen flowing on the other side of the membrane. Oxygen molecules diffuse through the membrane into the high-purity nitrogen on the other side and are carried by the flowing nitrogen to the sensor. By analyzing the oxygen concentration measured by the sensor, oxygen permeability test data is obtained after reaching permeation equilibrium.

Technical characteristics of oxygen permeability tester for drug packaging materials

1、 High precision measurement

Sensor technology: Testers typically use high-precision Coulomb oxygen sensors or similar high-precision gas analysis instruments to accurately measure the permeability of the tested sample to oxygen, ensuring the accuracy and reliability of the test results.

Data calibration and compensation: The tester can automatically calibrate and compensate for environmental factors such as temperature, humidity, etc., further improving measurement accuracy. 2、 Automation and Intelligence

Automated control: The tester is equipped with an automated control system that can automatically complete the testing process, including sample clamping, gas supply, pressure regulation, data acquisition, etc., to improve testing efficiency.

Intelligent software: Testers are usually equipped with intelligent software interfaces, which are easy to operate and can display test results in real time for data processing and analysis. The software also supports multi format storage and data output, including experimental reports Excel、 Cloud sharing, etc., facilitate data management and comparative analysis for users.

In summary, the oxygen permeability tester for pharmaceutical packaging materials has wide application value in the pharmaceutical packaging industry due to its high-precision measurement, automation and intelligence, multi chamber testing and wide applicability, stable and reliable testing environment, as well as repeatability and accuracy.
