Vacuum Leak Tester
Product Code: UT-VAW
The vacuum leak tester tests the integrity of the bag seal. The vacuum chamber is evacuated so that the sample immersed in water generates a pressure difference between inside and outside; the out gassing of the sample is then observed to determine the sealing performance of the sample. By vacuuming the vacuum chamber, the internal and external pressures of the sample are generated. Observe the expansion of the sample and its shape recovery after releasing the vacuum to determine the sealing performance of the sample.
