Vacuum Decay Method

In line with the FDA approved ASTM F2338-09 standard test method and USP 1207 guidelines, the Multi-Q with vacuum decay method is developed to detect leaks in vials, ampoules, bottles, pre-filled syringes, blow fill seal strips, medical devices, trays and other containers containing water-based liquid, down to 5μm*.

Multi-Q Vacuum Decay

The Multi-Q vacuum decay method is quick and easy. The sample is placed into a closely fitting chamber that is specially designed based on sample type and size. Once enclosed, vacuum is applied to the chamber. The vacuum level inside the chamber and any changes in vacuum are measured over a predetermined test time using absolute and differential pressure transducers. An increase in pressure that exceeds the predetermined pass or fail parameters indicates the presence of a leak.

  • Vacuum Decay

    How does vacuum decay testing work?

    To conduct a vacuum decay test, a container is placed in a tightly fitted chamber which is evacuated to a predetermined level of vacuum. After reaching the pre-set vacuum, a sensor measures the vacuum level over a predetermined time.

    If the integrity of the container under test has been compromised (it has a leak), there will
    be a rise in pressure measured inside the chamber. This will result in a) a gross leak, if the vacuum doesn’t reach the pre-set vacuum level; b) a medium leak, if the vacuum level drops below a pre-set vacuum level during the test or c) a decay or micron leak, if the vacuum level exceeds the decay limit during the test time.
