MLT-01 Micro Leak Tester

Introduction

In today’s competitive market, ensuring the integrity of packaging is crucial for maintaining product quality and consumer safety. Non-destructive leak testing equipment plays a vital role in achieving this goal. The MLT-01 Micro Leak Tester is designed to provide accurate and reliable leak detection for nonporous, rigid or flexible packages, making it an essential tool in various industries, including pharmaceuticals, food packaging, and medical devices.

Understanding ASTM F2338

What is ASTM F2338?

ASTM F2338 is a critical standard that outlines the testing methods for evaluating the integrity of sealed packages through non-destructive leak testing. This standard ensures that products meet stringent quality and safety criteria, particularly in regulated industries. The methods defined in ASTM F2338 are crucial for identifying potential leakage, which can compromise product integrity and lead to significant financial losses.

Test Methods Defined by ASTM F2338

The ASTM F2338 standard includes several methods for detecting leaks, with a focus on the vacuum decay method. This approach involves applying a negative pressure to the test package and monitoring any pressure increase, indicating a leak. Compared to other leak testing methods, the vacuum decay method is highly sensitive and efficient, making it suitable for various applications.

MLT-01 Micro Leak Tester

System Description

The MLT-01 Micro Leak Tester utilizes a sophisticated design that features a network of conduits and valves connecting a test chamber to a high-resolution pressure sensor and an external vacuum source. The system is equipped with a PLC control unit and an HMI touch screen, allowing for intuitive operation. An external gas flow meter ensures optimal system performance, while the specially designed test chamber securely encloses the test package and can incorporate tooling to restrict movement or expansion as needed.

Test Process

The testing process with the MLT-01 Micro Leak Tester consists of four primary stages:

1. FILL Stage: Secure the sample in the chamber and apply negative pressure to create a controlled environment.
2. SETTLE Stage: Allow the system to accommodate any component stretching or flexing that may occur under negative pressure.
3. TEST Phase: Measure any pressure increase during this phase. A significant change indicates the presence of a leak.
4. VENT Stage: Release the remaining negative pressure to the atmosphere and evaluate the results. If the sample stays within the specified range, it PASSES; otherwise, it FAILS.
