Vacuum leak tester

Vacuum Decay Leak Tester specializes in the detection of leaks in ampoules, vials, injection bottles, freeze-dried powder injection bottles, and pre-filled packages.

Applications

1. Automotive Industry

In automobile manufacturing, sealing performance is directly related to the safety and stability of the entire vehicle. Micro-leak testing ensures the sealing performance of automotive components, such as fuel tanks, braking systems, and exhaust pipes, under high-pressure environments, effectively improving the overall performance and safety of the vehicle.

2. Medical Devices

Leaks in medical devices can have serious consequences. In the medical field, using vacuum leak testers for rigorous quality control to ensure that equipment such as syringes and medical tubing maintain good sealing performance is crucial for patient safety.

3. Food Packaging

To maintain the freshness and safety of food, food packaging materials must have excellent sealing performance. Micro-leak testing can effectively detect the sealing effect of packaging materials, preventing food spoilage due to packaging defects.

4. Pharmaceutical Industry

Pharmaceutical companies have extremely high requirements for the clean environment during the production process. Vacuum leak testers can be used to test the sealing performance of pharmaceutical production equipment and containers, ensuring the sterility and safety of products.

Test Procedures

Single-sensor testing: Uses a single pressure sensor to monitor pressure changes within the test chamber throughout the process.

Dual-sensor testing: Combines a pressure sensor and a differential pressure sensor to provide more accurate measurement data, especially suitable for detecting very subtle leaks.

Multi-sensor testing: Further enhances accuracy by adding additional types of sensors (such as force sensors) for a more comprehensive assessment of leaks.
