How to Choose the Right Leak Testing Equipment

Choose the Right Leak Testing Equipment

1. Determine Test Requirements

Identify packaging type: flexible, rigid, or semi-rigid.

Establish acceptable leakage rate thresholds.

Consider sample pretreatment and environmental conditions.

2. Select Appropriate Detection Methods

Pressure decay/vacuum decay method: Suitable for rigid containers.

Bubble Release/Vacuum Chamber Method: Suitable for flexible packaging.

Helium Trapping Method: High-precision applications (pharmaceuticals, medical devices).

Dye Penetration Method: Visual inspection of seals and closures.

Select online/offline inspection based on production speed and batch size.

3. Evaluate Equipment Capabilities

Inspection Performance: Sensitivity, accuracy, repeatability; compliance with ASTM, ISO, FDA standards.

Operational Efficiency: Cycle time, automation level, batch/continuous testing capability.

Material & Packaging Compatibility: Adaptability to diverse shapes, sizes, and materials; modular/customizable design.

4. Evaluate Supplier Expertise & Support

Industry experience and compliance knowledge base.

Customization capabilities for fixtures, test chambers, and software profiles.

Technical support, training, calibration, and maintenance service systems.

5. Common Pitfalls to Avoid

Failure to establish clear leakage rate thresholds.

Neglecting environmental condition impacts.

Inappropriate test chamber sizing.

Overlooking future packaging requirement changes.

Misjudging that a single testing device can accommodate all packaging types.
