Bubble Leak Tester BLT-V
The BLT is designed to test the integrity of sealed packs (with some headspace) via a bubble emission test. Easy to use for leak tests and burst tests on single or multiple packs.
Description
Sealed packs are placed into the bubble leak tester water bath, a soft close hinged lid submerges them below the water level. An isolation switch is opened causing the pack internal pressure to increase to the pre-set pressure. The operator observes the packs through the chamber walls, a steady stream of bubbles indicates the location of any leaks. Burst testing can be conducted by gradually increasing the pressure and observing the pressure gauge when the pack opens.
For the positive pressure BLT, see Bubble Leak Tester BLT-P.

Features & Benefits
- Leak / Seal integrity tests to pre-set pressures.
- Burst testing to determine seal strength.
- No trace gas in pack needed, no mains electric, semi-portable.
- Simple & fast for quality control.
- Drain / Fill valve, convenient for regular change of water.
- Various water tank sizes.
Also available is the BLT-P range which tests the integrity of sealed pack using a positive pressure via a needle / tube inserted in a pack. This alternative model meets standard ASTM F2096.
