Barrier Properties Assessment of Packaging for Oxygen-Sensitive Medical Diagnostic Kits

Medical diagnostic kits containing oxygen-sensitive components necessitate packaging with robust moisture and oxygen barriers to ensure the accuracy and reliability of their diagnostic tools. Oxygen and moisture can degrade sensitive reagents and sensors, leading to inaccurate results. Materials such as barrier foil laminates, flexible barrier films, foil pouches, rigid plastics (HDPE, LDPE, PP, PS), and glass vials or ampoules are commonly employed.

To maintain product integrity, packaging for these kits must incorporate features like tamper-evident seals, easy-peel designs, and durable construction, especially when protecting sensitive electronic components. To verify these properties, packaging materials undergo rigorous testing.

Oxygen permeation testing measures the rate at which oxygen passes through the packaging, crucial for oxygen-sensitive components, while moisture vapor transmission rate testing determines the material's resistance to moisture ingress.

Labthink C406H Oxygen /Water Vapor Transmission Rate Test System is based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249，ISO 15106-2 and other relevant standards to provide high precision and high efficiency oxygen and water vapor transmission rate tests for high and medium gas barrier materials. It is suitable for testing the oxygen and water vapor transmission performance of films, sheets and related materials in the fields of food, medicine, medical devices, daily chemicals, photovoltaic, electronic and many others.

The sterile barrier integrity and the physical performance are thoroughly evaluated as well. For instance, tensile strength and elongation tests assess the material's ability to withstand stretching and pulling.

By conducting these comprehensive tests, manufacturers can confidently ensure that the packaging safeguards the medical oxygen diagnostic kits, preserving their safety and performance throughout their intended shelf life.
