Typical Applications
Packaging Compatibility Studies
Provides comparable data to evaluate and select optimal packaging component combinations.
System Performance Verification
Assesses the long-term stability and low-end sensitivity of high-resolution leak detectors (e.g., helium mass spectrometers).
Process Optimization
Compares how different instruments or parameters respond to identical micro-leaks, informing project refinement.
Core Value
Built on over twenty years of specialization in package integrity, our capillary standards translate deep research into reliable, practical laboratory tools.
○ Proven Reliability: Our design is informed by extensive research into package behavior and leak physics, ensuring a representative and stable leakage model.
○ Precision Compliance Support: Aligned with global regulatory expectations for "challenge samples," our graduated series enable systematic validation of method detection limits.
○ Cost-Effective Performance: Through optimized manufacturing, we deliver better performance at a practical cost, making advanced sensitivity validation an accessible part of your quality system.

More Information
Can one instrument test different package sizes?
Yes. Different package sizes and shapes can be tested by changing the test chamber, fixture or sample holder.
Can the system test pharmaceutical vials?
Yes. Vacuum decay testing can be configured for vials containing powder, lyophilized products or medicinal liquids. A package-specific chamber is normally required.
Which mode should be used for flexible packaging?
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.
