Seal Integrity Testing After Sterilization (EO, Gamma, Steam)
The integrity of a medical device's packaging is paramount to ensuring the sterility and safety of the product throughout its shelf life. Post-sterilization seal integrity testing ensures that the packaging remains intact after exposure to sterilization methods such as Ethylene Oxide (EO), Gamma irradiation, or Steam Sterilization (autoclaving). This service is crucial for medical device manufacturers aiming to comply with regulatory standards and ensure product safety.
The primary focus of this service is on detecting any breaches in the packaging that may have occurred during the sterilization process. A compromised seal can lead to contamination, affecting both the sterility and shelf life of the packaged item. This testing is particularly important for single-use devices, as even a small breach can render the device unusable or potentially harmful.
Our laboratory utilizes advanced instrumentation and adheres strictly to international standards such as ISO 11607-3:2021, which provides guidelines on packaging integrity testing. The testing process involves several key steps:
- Sample Preparation: Packaging samples are collected from the production line.
- Visual Inspection: Initial checks for visible defects or breaches.
- Pressure Decay Method: This method measures changes in pressure within a sealed chamber, indicating any leaks.
- Bubble Testing: A pressurized fluid is introduced into the package to detect leaks by observing bubbles formed at breach sites.
The results of these tests are meticulously documented and reported. Compliance with regulatory requirements such as those set out in 21 CFR Part 820, ISO 11607-3:2021, and the European Union’s MDD (Medical Device Directive) is ensured.
| Method | Equipment Used | Key Parameters Measured |
|---|---|---|
| Pressure Decay Method | Digital pressure sensor, Vacuum pump, Pressure chamber | Leak rate in liters per minute (L/min) |
| Bubble Testing | Syringe with pressurized fluid, Bubble detection camera | Visual detection of leaks |
The Seal Integrity Testing after Sterilization ensures that medical devices maintain their sterility and integrity throughout the shelf life. This service plays a critical role in maintaining compliance with regulatory standards and ensuring product safety.
Scope and Methodology
The scope of Seal Integrity Testing After Sterilization (EO, Gamma, Steam) includes the evaluation of packaging integrity after exposure to various sterilization methods. This service ensures that any breaches in the packaging do not compromise the sterility or shelf life of the medical devices.
| Method | Description | Key Considerations |
|---|---|---|
| Pressure Decay Method | A digital pressure sensor measures changes in pressure within a sealed chamber to detect leaks. | The method is sensitive and can identify minute breaches. |
| Bubble Testing | Pressurized fluid is introduced into the package, and any leaks are detected by observing bubbles formed at breach sites using a camera. | This test provides visual confirmation of leak locations. |
The methodology involves collecting samples from the production line, performing initial visual inspections for visible defects, followed by the application of either the Pressure Decay Method or Bubble Testing. The results are documented and reported to ensure compliance with regulatory standards such as ISO 11607-3:2021.

- Quality Control: Regular testing ensures that packaging integrity is maintained throughout the production and distribution processes.
| Sterilization Method | Testing Frequency | Potential Impact on Packaging Integrity |
|---|---|---|
| Ethylene Oxide (EO) | Every production batch and after every 100 sterilization cycles | Breaches can occur due to the high temperature and humidity. |
| Gamma Irradiation | After each sterilization cycle | Breach risk increases with higher doses of radiation. |
| Steam Sterilization (Autoclaving) | Every production batch and after every 50 sterilization cycles | Breaches can occur due to pressure changes during the process. |
