Labthink C690H Non-Destructive Leak Detector uses a vacuum-based testing method (and also a positive pressure method) to find tiny leaks in different kinds of containers. It's built according to international standards like ASTM F2338 and is particularly useful for checking various packaging in industries like food, pharmaceuticals, daily chemicals, and electronics, such as vials, ampoule, cartridge bottles, infusion bottles and prefilled syringes. How it works It works by placing the sample in a sealed chamber, creating a vacuum, and then using sensors and a fluid dynamics model to calculate the leak rate and the size of the leak based on how fast the pressure drops. It can operate in two modes: Vacuum mode: It creates a negative pressure (vacuum) around the sample and measures how quickly the pressure inside the sample drops. This works well for most packaging types because the vacuum helps to "pull" out any leaks, making them easier to detect. ...
