CTEX-I Leak test box

Convertible model and scalable

It is used to test, by vacuum, the tightness of the packaging of solid heat-sealed or capped products dans in packaging containing air, such as blisters, sachets, doypacks, yogurt, trays, etc.

The presence of a leak is detected with the appearance of bubbles in the water during depression, and so is precisely localized. A perforated plexiglas plate, called a presser, allows the product to be held in immersion.

This model is available with a vacuum pump system for vacuuming.
