Application

Testing the integrity of package seals helps ensure that the packaging provides required

product protection. Sustainable packaging alternatives, lower cost packaging, and variations

in production line sealing parameters are frequently assessed with seal integrity tests.

Maintaining the reliability of package seals is critical for product quality and safety.

Test Description

A sample is placed into the chamber filled with water. After the lid is put back.

the control unit start to extract the air inside chamber out, until the preset vacuum

is achieved. Because of the pressure difference between inside and outside of sample, air in it will

escape if there is a small leak. The leak is shown by a stream of bubbles from the leak area.

Technical Features

LT-02 leak tester is the first generation automatic vacuum

tester introduced by Cell Instruments. The ASTM D3078 is

the standard test method for determination of gross leaks

in flexible packaging containing a headspace gas by bubble

emission. The test is conducted by submerging the test

specimen in the immersion fluid within the confines of a

vacuum chamber.

☛To achieve stable vacuum and considering the fact that

compressed air is easier to be obtained at user facility, we use Venturi tube for a high level of

vacuum up to –90KPa.

☛Precious and long test time setting.

☛SMC branded vaccum pressure switch.

☛Strong and clear chamber provided, and diffferent sizes and shapes could be customized

☛It could be modifed to work with vacuum pump, to achieve higher vacuum(for ASTM D4991)
