Testing principle:

Microbial challenge sealing test, also known as microbial immersion sealing integrity test, is usually conducted simultaneously with simulated filling. By simulating the filling of the culture medium according to the simulation filling verification plan, followed by plugging and capping, the visual inspection is qualified. After sterilization in a validated sterilization cabinet, immerse the sealing surface of the container in a high concentration bacterial solution to ensure that the culture medium inside the sample container fully contacts the inner surface of the seal. The neck of the sample and the outer surface of the seal should be fully immersed in the bacterial suspension. After soaking for a certain period of time, remove it and regularly cultivate it to check for microbial invasion and determine the integrity of the container sealing system. At the same time, a positive control test needs to be conducted to confirm the growth promoting ability of the culture medium. In testing, challenges such as vacuum or overpressure are usually applied,MIT-L20The microbial challenge method sealing tester can meet the requirements of relevant negative pressure vacuum and positive pressure overpressure test conditions.

Test application:

Microbial challenge method (immersion) sealing test for packaging systems of composite bags, blister packaging, oral solid medicine bottles, glass infusion bottles, glass injection bottles, glass ampoules, oral liquid bottles, hoses and other products used in drug packaging.
