Liquid Microbial Penetration Testing of Sterile Barrier Systems
The integrity of sterile barrier systems is a critical concern in medical device manufacturing. Ensuring that these barriers remain intact and effectively exclude microorganisms throughout the shelf life of a product is paramount to patient safety and regulatory compliance.
At Eurolab, our expertise in packaging integrity testing extends to specialized methods for assessing the resistance of sterile barrier systems against liquid microbial ingress. This service leverages advanced methodologies that simulate real-world conditions, providing data critical for ensuring the reliability and performance of medical devices.
The process involves subjecting a defined volume of liquid inoculated with microorganisms (such as Escherichia coli, Pseudomonas aeruginosa, or other relevant pathogens) to the barrier system. The specimen is then incubated under controlled conditions, and any microbial penetration detected indicates potential vulnerabilities in the packaging.
This testing aligns with international standards such as ISO 11607-5:2022, which specifies procedures for determining microbial ingress into medical devices, particularly focusing on the packaging of sterile barrier systems.
The test parameters are meticulously controlled to reflect actual storage and handling conditions. Specimen preparation involves selecting representative samples that mimic typical field conditions. This includes ensuring the correct volume and type of inoculum, as well as replicating environmental factors such as temperature and humidity.
Instrumentation used in this testing may include incubators for maintaining consistent temperatures during the test period, laminar flow hoods for aseptic handling, and specialized equipment for monitoring microbial growth. The results are reported using detailed protocols that include both quantitative measures of microbial counts and qualitative observations on specimen integrity.
The primary goal is to identify any breaches in the barrier system before they could lead to contamination during use, thereby ensuring product safety and compliance with regulatory requirements.

Use Cases and Application Examples
| Use Case | Description |
|---|---|
| Sterile Barrier Testing for Implants: | Testing ensures that implant packaging maintains sterility throughout the shelf life, reducing risks of infection. |
| Liquid Penetration Testing for Drug Delivery Devices: | Evaluates the integrity of containers used in drug delivery systems to prevent microbial contamination. |
Our liquid microbial penetration testing is particularly relevant for packaging materials such as polyvinyl chloride (PVC), polyethylene terephthalate (PET), and metallized films. These materials are commonly used in sterile barrier systems due to their mechanical strength, chemical stability, and barrier properties.
