The Bottle Leak Tester (BLT) is an advanced solution designed to detect leaks in a wide variety of bottle types and shapes. Utilising the non-destructive vacuum decay method, the BLT ensures that bottles are properly sealed without compromising their contents. This highly precise system offers an important tool for industries such as food, beverage, and pharmaceuticals.

How the BLT Works

The BLT employs the vacuum decay method, a trusted standard (ASTM F2338) for detecting leaks by measuring pressure changes in a sealed chamber. The machine’s pre-formed, FDA-approved membrane wraps securely around the bottle, creating a minimal measuring space that allows it to detect both large and micro leaks. This method ensures that the bottle’s top, body, or any part of the container is properly tested for leaks while protecting the contents of the package.

  1. Non-Destructive Testing: The BLT tests bottles without damaging the packaging or the contents, allowing products that pass the test to be returned to the production line. This reduces waste and operational costs, making the system highly efficient.
  2. Adaptable for Various Bottle Types: The BLT can handle a wide range of bottle shapes and sizes, ensuring flexibility for different product lines. It’s ideal for testing both the entire bottle and specific parts, such as the seal or cap.
  3. High Sensitivity for Micro Leaks: With the ability to detect leaks as small as 0.9 cm³/min, the BLT provides precise feedback, making it perfect for industries where even the smallest packaging flaw could compromise product quality.
  4. Quick and User-Friendly Operation: The system provides real-time results with simple pass/fail indicators, enabling operators to immediately determine if a bottle meets quality standards. This instant feedback helps streamline the quality control process, reducing downtime on the production line.
