HMI Touch Screen Vacuum Leak Tester, Digital Vacuum Leak Tester, Vacuum Leak Test Chamber, Vacuum Leakage Tester, Package Leak Tester, Packaging Leak Tester, Pouch Leak Tester, Bottle Leak Tester, Bubble Emission Leak Tester, Bubble Leakage Tester, Package Integrity Tester, Seal Integrity Tester, Vacuum Leak Detection Machine, Flexible Packaging Leak Tester and Packaging Leak Testing Equipment.

Working Principle – Bubble Emission Technique

The test sample is placed inside a transparent vacuum chamber and immersed in water or a suitable test liquid. The chamber is closed, and a controlled vacuum is applied through the HMI touch screen.

If the pouch, bottle or package contains a leak, pinhole, crack or defective seal, air escapes from the damaged area and produces visible bubbles. The operator can observe the bubbles through the transparent chamber and identify the leakage point.

Test Procedure

1. Place the pouch, bottle or package inside the chamber.
2. Fill the chamber with water or a suitable test medium.
3. Close and lock the vacuum chamber lid.
4. Select the required vacuum level and test duration on the HMI touch screen.
5. Start the test cycle.
6. Observe the sample for bubble formation.
7. Visible continuous bubbles indicate leakage or package failure.

8. Applicable Standards

   The HMI Touch Screen Vacuum Leak Tester can be configured according to relevant standards and customer requirements, including:

   • ASTM D3078 – Determination of leaks in flexible packages by bubble emission
   • ASTM F2096 – Detecting gross leaks in medical packaging by bubble emission
   • ISO 11607 – Packaging for terminally sterilized medical devices, where applicable
   • Applicable IS/BIS and customer-specific test methods

   Vacuum level, test time, chamber size and sample fixtures can be customized according to the package type and testing requirement.
