Stable and quality leak tester from China Bubble emission method ASTM D3078 model 0~-90 KPa Test Range

The leak tester is a crucial instrument for accurately detecting leaks in flexible packaging. Utilizing the bubble emission method, in compliance with ASTM D3078, this device is designed to identify gross leaks and ensure the integrity of packaging materials. The testing process involves generating positive pressure inside the pouch after vacuum evacuation, forcing small leaks to reveal themselves as air bubbles.
This leak tester is ideal for various industries, including packaging, food, pharmaceuticals, and beverages, where reliable leak detection is essential for maintaining product quality and preventing contamination. Its robust features and customizable options make it a valuable tool for laboratories and quality assurance teams worldwide.
Key Features of the Leak Tester

1. Stable Vacuum Ejector Technology: The leak tester uses a vacuum ejector that outperforms traditional vacuum pumps in creating a stable internal pressure, crucial for consistent and accurate test results.
2. Digital Control Settings: Equipped with a digital interface, users can set the vacuum degree and test duration with precision. This feature enhances the flexibility and repeatability of testing.
3. Automatic Vacuum Maintenance: The leak tester automatically maintains the vacuum level throughout the test cycle, ensuring steady conditions for optimal results.
4. Air Back-Flushing Feature: This built-in feature prevents contamination by automatically flushing out air between testing cycles, maintaining cleanliness in the chamber.
5. User-Friendly Operation: Designed for ease of use, the tester requires minimal training for operation, making it an excellent choice for fast-paced laboratory environments.
6. Durable PMMA Chamber: The transparent PMMA chamber is thick and high-quality, offering superior durability and allowing easy observation of test progress.
7. Customizable Chamber Sizes: We understand that one size does not fit all. Our leak tester offers customizable chamber sizes to meet the specific needs of your applications.

Applications of the Leak Tester
This leak tester is extensively used for testing flexible packaging such as pouches, bags, and sachets, ensuring they meet stringent quality control standards. It is suitable for a variety of industries, including:

• Packaging Industry: Ensuring the airtight seals of food, beverage, and pharmaceutical products.
• Food & Beverage Packaging: Detecting leaks that could compromise product freshness or safety.
• Pharmaceutical Industry: Ensuring drug packaging integrity to prevent contamination and product degradation.
• Research and Development: Testing new materials and packaging solutions to verify their leak resistance.

How the Leak Tester Works
The leak tester operates using the bubble emission method, in line with ASTM D3078. Here's a breakdown of the process:

1. Vacuum Application: The packaging material (typically a pouch or bag) is placed inside the testing chamber. A vacuum is drawn inside the chamber to simulate the conditions under which the packaging will be tested.
2. Positive Pressure Creation: After the vacuum is applied, positive pressure is created inside the pouch. Any small leaks within the packaging will force air to escape, creating visible bubbles.
3. Observation of Leaks: The leak tester allows for easy visualization of the leaks through the transparent PMMA chamber, enabling technicians to quickly identify packaging flaws.
4. Test Duration: The digital control interface enables precise settings for test duration and vacuum levels, ensuring repeatable, reliable results every time.
