Container Closure Testing

The container closure system for a drug product provides critical protection for stability and sterility. ARL offers USP <1207> container closure integrity testing (CCIT) on IV bags, syringes, cassettes, and vials. Three types of leaks that can be detected during CCIT include: 

1. Entry of microorganisms
2. Escape of the product dosage form or entry of liquids or solids
3. Escape of nitrogen gas or entry of oxygen, water vapor, or air gase
