Understanding the Role of a Vacuum Leak Tester
A Vacuum Leak Tester works by creating a low-pressure (vacuum) environment inside a transparent chamber. The test sample is submerged in water within the chamber. When vacuum pressure is applied, any leaks present in the package will result in the formation of bubbles, making them easy to detect visually.
This method is especially suitable for detecting:
Pinholes in foil or plastic packaging
Weak seals in heat-sealed containers
Micro-cracks in rigid bottles or jars
Imperfections in blister packs and tubes
Why Industries Choose Pacorr Vacuum Leak Tester
Pacorr designs its leak testers to meet the evolving needs of production and quality labs. Here's what sets it apart:
✔️ Accurate Vacuum Generation
The tester ensures precise vacuum levels, making it ideal for repeatable and controlled testing conditions.
✔️ Clear Visibility Chamber
The transparent acrylic chamber enhances bubble visibility for instant leak detection.
✔️ User-Friendly Operation
Simple controls, fast vacuum buildup, and intuitive layout enable smooth testing even by new operators.
✔️ Durability and Safety
Built with chemical-resistant, tough acrylic materials for long-term performance in busy QC environments.
✔️ Conforms to International Standards
Follows ASTM D3078 and relevant ISO protocols for flexible and rigid packaging.
How to Perform a Vacuum Leak Test
The leak detection process is easy to implement on-site:
Fill the chamber with water to the desired level.
Place the test sample (e.g., pouch, bottle, pack) inside the water.
Close the lid and activate the vacuum pump.
Hold vacuum pressure for a set duration (usually 30–60 seconds).
Observe bubble formation, if any, from the test sample.
Release vacuum, remove sample, and record the outcome.
If no bubbles appear, the sample is considered leak-proof. If bubbles are present, a leak is confirmed.
