MC-B82 Negative Pressure Leak Detector Series

The MC-B82 is a versatile, cost-effective solution for Container Closure Integrity Testing (CCIT) and package seal quality inspection. Designed for pharmaceutical QC laboratories and packaging development, this system utilizes a vacuum system to support three distinct leak test methodologies under one platform: Dye Ingress, Bubble Emission, and Microbial Ingress. Its transparent acrylic chamber and precise vacuum control enable operators to visualize leaks, qualify package integrity per USP <1207> guidelines, and validate Maximum Allowable Leakage Limit (MALL) without the need for expensive tracer gases or complex calibrations.

  • Frequently Asked Questions
  • Q:

    Can one instrument test different package sizes?

    A:

    Yes. Different package sizes and shapes can be tested by changing the test chamber, fixture or sample holder.

  • Q:

    Can the system test pharmaceutical vials?

    A:

    Yes. Vacuum decay testing can be configured for vials containing powder, lyophilized products or medicinal liquids. A package-specific chamber is normally required.

  • Q:

    Which mode should be used for flexible packaging?

    A:

    Pressure decay is generally more suitable for flexible packages that may deform significantly when exposed to vacuum. The final method should be confirmed through package evaluation and feasibility testing.
