Maintaining Food Quality Using Vacuum Leak Tester

 

These bacteria can be root of severe diseases. Such conditions can be prevented by testing the leakages of the packaging films. Vacuum Leak Tester is a reliable device for leakage tests in wrappers, films, packets, sachets and pouches. The device functions as releasing vacuum pressure in an apparatus at a defined value for a specific time period. If specimen shows any change in shape, means it is having a leakage and should be rejected.

 

 

PRESTO manufactures Vacuum Leak Tester Digital-Eco Model for such leakage tests. Presto Vacuum Leak Tester contains a vacuum generator, a transparent chamber, and a vacuum meter. The transparent chamber known as desiccator is an acrylic sheet container holding a drying agent for reducing moisture. The test sample is placed in desiccator; the vacuum is released by turning the knob in clockwise direction. Desiccator is placed in fixed position. Vacuum Pressure of up to 675mm/hg is released and test continues for 1 minute. On the completion of test time, the vacuum release is stopped. The sample is either passed or failed according to need of quality. As per international standards ASTM F 2338-09, ASTM D 4991-07, ASTM D6653 the instrument is reliable and give accurate results.
