1.1 INTENDED USE
The LeakVIEW is a package testing system based on the Pharmaceutical industry standard Bubble
Emission test method. The unit may also be used without water, where the visible leakage of pack
contents may be observed.
The system is intended for use in laboratory and manufacturing environments.
1.2 OPERATING PRINCIPLE
The LeakVIEW comprises a test chamber and vacuum generator controller. The vacuum and test time
may be programmed and monitored on the control panel. The test chamber is filled with water (enough
to cover the perceived range of packs when they are inflated), alternatively the test chamber may be
left empty for tests where visible pack content leakage is observed or for burst testing.
For a standard bubble emission test the following sequence takes place:
1.
The packs are placed in the chamber and the lid is closed. This causes the pressure plate to
submerge the pack.
2.
The operator presses the
START
button. This causes the air supply to the vacuum generator to
be switched on for the EVACUATION phase.
3.
When the target vacuum is achieved, the vacuum generator is switched off and the system en-
ters then vacuum HOLD phase, where the vacuum will be held constant.
4.
The operator observes the pack for any bubble stream due to a pin hole or seal defects.
5.
When the test time has elapsed, the system enters the VENT phase and the vacuum is de-
stroyed, the lid can then be opened and the pack removed.
