Overview
The vacuum attenuation method packaging sealing tester is specialized in non-destructive positive and negative pressure micro leakage testing of various empty/pre filled syringes, water and powder injection bottles (glass/plastic), filling and capping bottles, milk powder cans, other hard packaging containers, electrical components and other samples. This sealing instrument adopts advanced design and rigorous, scientific calculation methods to ensure its rapid testing, high accuracy, and high stability. It can also meet users' non-standard (software or testing fixture) customization needs.
Product Details
Product Introduction:
Vacuum attenuation method packaging sealing testerProfessional application for non-destructive positive and negative pressure micro leak testing of various empty/pre filled syringes, water and powder injection bottles (glass/plastic), filling and capping bottles, milk powder cans, other hard packaging containers, electrical components and other samples. This sealing instrument adopts a novel design and rigorous, scientific calculation method to ensure its fast testing, high accuracy, and high stability. It can also meet users' non-standard (software or testing fixture) customization needs.
| Comparison of Leakage Test Methods | ||
| Compare projects | Water bath test | Micro leak detection |
| The minimum detectable aperture | 10~20μm |

| Destructive/Non destructive | destruction test | Non destructive testing |
| test medium | Water (requires maintenance) | air |
| human error | Small leaks are difficult to detect | Numerical management, no need for manual labor |
| Leakage point confirmation | Can locate the leakage point | Cannot confirm the leakage point |
Testing principle:
Determine whether there is gas leakage in the test chamber by comparing the pressure between the standard chamber and the test chamber.
The reference container and the tested container are both sealed and leak free. After placing the sample into the tested container, the pressure change of the tested container is caused by gas leakage of the sample. The pressure change is detected by a differential pressure sensor, and the leakage hole diameter and leakage flow rate can be derived through formula calculation
Technical advantages:
★ Optional built-in 10 inch touchscreen computer and external computer;
★ It can accurately display the leakage aperture (≥ 1 μ m) and leakage amount;
The test chamber and the host are arranged separately, and one set of test chambers is suitable for more than 5 specifications of samples;
★ The testing chamber is made of aluminum alloy or stainless steel, with pneumatic clamping;
★ Built in flow meter, one click completion of flow calibration;
★ Equipped with three calibration methods: zero point, leak hole, and flow rate;
The test results have three judgment modes: pressure attenuation, leakage aperture, and leakage flow rate
The test result shows that the flow error is less than or equal to 0.1 sccm
★ Vacuum resolution ≤ 1pa/0.01mbar/0.0001psi
★ Capable of converting testing units such as kpa/mbar/pa/psi
★ Can detect positive and negative pressure attenuation tests for various soft and hard samples such as penicillin bottles, infusion bags, contact lenses, milk powder cans, electronic accessories, etc;
