Gross Leak Tester
LSST-02
LSST-02 Gross Leak Tester, adopt positive pressure method, is used to test gross leaks in packaging by internal pressurization (bubble test) of sterile medical device package. It is also applicable to quantitative determination of seal strength, seal quality, burst pressure, seal integrity, compression resistance, torsion force and joint/disengaging force of various flexible packages, aseptic packages, plastic tamper-evident closures, flexible tubes, caps and other materials.
Product Features
5 test modes including gross leak, burst, creep, creep-to-failure, pressure maintaining
7 inch HD LCD, touch screen interface, displaying test data and curves in real time
Dual test methods of restraint distension and unrestraint distension for choice.
Safety design such as over-voltage safety protection and power-down memory ensure the stability of the system
Equipped with standard RS232 interface, which is convenient to PC connection and data transmission
Originality Design
Dual load cells for large and small test range, expand the test range
Adopts high-precision electronic flow controller to realize precise control of gas flow
Pressure and time can be preset
With a powerful data storage function, storing up to 100,000 test records
Results are automatically determined and test data can be printed
The test frame and inflatable head can be raised and lowered for easy operation
Provide various customized leak test functions
Test Principle
There are 5 test modes:
Burst Test: Test the maximum burst pressure of the package (the maximum pressure that the package bears until it fails).
Creep Test: Test the seal strength of the package (the pressure drop value of the package within specific time).
Creep to Failure Test: Test the seal strength of the package (Time to failure of the test package after the set pressure drop value).
Pressure Maintaining Test: Test the seal strength of the package (The test package maintains a specified pressure for a specific time).
Gross Leak Test: Test gross leaks in packaging by internal pressurization (bubble test).
