Leak Test Device

Standard: ASTM D3078, ASTM E515, GB/T 15171

The STC Leak Testing Device is professionally designed for the leak testing of packaging for food, pharmaceuticals, medical devices, daily-use chemical products, automotive parts, electronic components, stationery, and various other industrial products. This device can also be used to test the sealing performance of samples after ball/weight drop and compression tests.

Test Principle

First, immerse the sample in the water inside the vacuum chamber, and then evacuate the vacuum chamber to create a differential pressure between the inside and outside of the sample. The leak characteristic can be determined by observing the continuous emergence of bubbles from the sample and the sample expanding and returning to its original state after the vacuum is released.

The STC Leak Testing Device can be used to determine the leak characteristics of the following materials:

Basic Applications

• Glass bottles, tubes, jars, and boxes
• Plastic bottles, tubes, jars, and boxes
• Metal bottles, tubes, jars, and boxes
• Paper-plastic composite bags, pouches, and boxes

Extended Applications

• Ballpoint pen refills
• Electronic components
• Medical devices

Features

• The device uses a digitally preset vacuum degree and vacuum holding time to guarantee the accuracy of test data.
• Its main components have stable and reliable performance and are imported from countries known for their production with these features.
• Samples can be tested under a pre-set vacuum condition with automatic constant pressure compensation.
• Professional software supports automatic backwashing and test termination functions to provide a safe testing environment.
• This device is controlled by a microcomputer featuring a PVC operation panel and an LCD screen, making it easy for users to perform the testing process and view test data.
