Container Closure Integrity Testing Ensuring the integrity and safety of your pharmaceutical containers


The crucial role of Container Closure Integrity Testing (CCIT) for patient safety

To ensure patient safety, maintaining the sterility and stability of drug products is a critical task for drug containment solutions. Container Closure Integrity (CCI) is essential in preserving the efficacy of a drug and preventing contamination. Effective CCI testing verifies that the final product is safe and effective when injected into a patient.

SCHOTT Pharma's services for CCIT assist customers in testing various containment systems to assess their suitability for specific applications, as well as compiling data for drug application submissions. We support data generation in compliance with global standards and authority requirements. Related methods and acceptance criteria ensure that pharmaceutical products can be trusted and approved for the market. With headspace analysis and dye penetration, we provide quantitative insights while adhering to traditional CCIT methods.

Headspace analysis – quantitative insights to CCI performance

Our Container Closure Integrity Testing (CCIT) employs a state-of-the-art approach, combining advanced equipment and precise analytical methods. We use a CCI test vessel in tandem with a headspace gas analyzer. Accommodating a wide range of container types and sizes, this setup is highly versatile and designed to expedite gas ingress in the presence of any container defects.

The core of our testing method is laser-based analysis. This method accurately measures changes in the headspace gas composition or pressure due to gas ingress, offering a highly sensitive and precise assessment of container integrity. This quantitative approach enables a time-resolved performance evaluation of the container’s closure system.

Our CCIT method is adaptable to various product specifications and container types, and applies validated mathematical models to determine the rate of gas ingress. This enables us to develop a customized and efficient CCIT protocol tailored to each specific product’s requirements.

Dye penetration test: This test is meticulously designed to detect microscopic leaks in container seals, which are pivotal to maintaining the integrity and safety of pharmaceutical products. Utilizing specialized dyes, this method is capable of revealing the smallest of breaches in seals. The dye’s distinct visibility under specific conditions allows for the precise and reliable detection of the most minute leaks, assuring the integrity of the seal and the safety and efficacy of the product within the container.
