Objective: To test the closure integrity of injection vials and ensure the quality of the drug. Methods: Vacuum decay method was used to test the closure integrity of injection vials. Firstly, the appropriate test chamber was selected, and negative and positive controls were properly prepared. The test parameters were setup and optimized. And then the sensitivity of the vaccum equipment was verified by the positive controls. Finally, the closure integrity of injection vials was tested, and the detection rate of vacuum decay method and dye ingress method were involved in the comparative studies. Results and Conclusion: The vacuum decay method had the highest performance in terms of detection sensitivity. This method has high sensitivity, simple operation and reliable results.
