i-OXTRA 7700 Oxygen Transmission Rate Testing System ---Medical Blister Package Test

Product catalog summary

Scope
The i-OXTRA 7700 Oxygen Transmission Rate Testing System is designed to measure the oxygen transmission rate of various materials including plastic films, composite films, sheets, high barrier materials, solar back sheets, aluminum foils, aluminized films, coextruded films, and containers made from plastics, rubber, glass, paper, and metals.

Test Procedures

Preparation: Prepare the test specimen according to specific standards. Insert nitrogen inlet and outlet pipes into the medical blister package and connect them to the integrated inner test chamber.
Enclosure: Enclose the package specimen in an aluminum foil cover and connect the oxygen inlet and outlet pipes to the inside of the cover.
Sealing: Secure the aluminum foil cover tightly and close the thermal container door.
Connection Check: Verify tubing connections, turn the stop valve to "ON," and adjust the pressure regulator to 0.15 MPa.
Parameter Setup: Set test parameters, select "Package" as the specimen type, and start the test.
Flow Observation: Monitor the flow of each test cell. The flow for Cells A, B, C, and Zero should be 10±1 ml/min, and oxygen flow should be 60±10 ml/min. Adjust flows using the valves as needed. A rotameter is required to check the oxygen flow rate.
Results: View test results and reports. Repeat procedures if necessary for additional tests.

E: Set up test parameters. Select specimen type “Package” and start the test. F: Observe the flow of each test cell in process of testing. The flow of Cell A, B, C and Zero should be 10± ml/min and the 1 flow of oxygen should be 60± ml/min. Otherwise the flow should be adjusted by turning the valves in clockwise or 10 counterclockwise direction. Turn in clockwise direction to decrease the flow, while counterclockwise direction to increase the flow. The flow rate of oxygen would not be displayed in test interface. A rotameter should be inserted into the multi-port to check the flow rate of oxygen....
