Leak and Seal Strength Tester LSST-01

Available from Cell Instruments Co., Ltd.China


Leak and Seal Strength Tester LSST-01 is an instrument for testing seal integrity based on pressure decay method. It is suitable for the quantitative determination of the sealing strength, heat sealing quality, whole bag burst pressure and sealing leakage performance of flexible packaging parts and aseptic packaging parts formed by various heat sealing and bonding processes.


Leakage and sealing strength tester LSST-01 adopts the positive pressure method, that is, the principle of pressure attenuation method. There are three test modes to choose from.

A. Rupture test: fill the test sample with a certain amount of gas to detect the maximum pressure before it ruptures.
B. Creep: Fill the sample with the pressure value of the 70% with the maximum pressure, keep it for a certain period of time, and observe whether the pressure changes.
C. Creep to rupture: Fill the sample with the maximum pressure 90% and record how long it will break.

Technical Characteristics:

1. One machine can realize three test modes: maximum rupture force, creep test and creep to rupture test.
2. PLC programmable controller realizes more accurate pressure and time control
3. 7 inch TFT man-machine interface full touch screen is convenient for test parameter setting and test operation.
4. The test results are automatically stored.
5. The program can be customized according to customer requirements.
6. Multiple test units can be selected.
7. RS232 interface and professional software (optional)
8. The constraint plate can be equipped according to the sample size.
