LSST-01 Leak and Seal Strength Tester System

Ensuring seal reliability is a key issue to maintaining product quality, preventing contamination, and complying with safety standards. The LSST-01 helps manufacturers perform tests that validate the integrity of various packaging forms, reducing the risk of leaks during transportation and storage.

Application

The LSST-01 Leak and Seal Strength Tester is designed to assess packaging integrity through pressure decay leak testing, a widely recognized method for confirming the durability and reliability of seals. It plays a crucial role in ensuring that packaging provides the necessary product protection, especially for industries like food, pharmaceuticals, medical devices, and consumer goods. The tester evaluates sustainable packaging options, identifies cost-effective sealing solutions, and monitors variations in sealing parameters during production.

Test Description

Test Method: Pressure Decay Leak Testing

Pressure decay testing is a trusted technique in the field of leak detection. This method works by pressurizing the sample to a target level and sealing off the air source. The system then monitors for a reduction in pressure, which indicates a potential leak.

With the LSST-01, users can perform:

Burst testing

Measures the point at which a package bursts due to increasing internal pressure.

Creep testing

Tests the package’s durability under constant pressure for a set time.

Creep-to-failure testing

Gradually increase the pressure until the package fails, assessing its threshold.

The Pressure Decay Leak Testing method allows precise control over pressure levels and sensitivity, making it suitable for detecting both large leaks and subtle pressure drops.

Frequently Asked Questions

What packaging types are compatible with the LSST-01?

The LSST-01 can test a wide variety of packaging types, including flexible bags, pouches, trays, and tubes, etc.

How does pressure decay testing ensure accurate leak detection?

Pressure decay testing monitors internal pressure drop within a package. Any drop beyond set thresholds indicates a leak, allowing for early detection and corrective action.

What is the benefit of multiple test modes (burst, creep, creep-to-failure)?

Multiple test modes provide flexibility in evaluating different aspects of package performance, from seal strength to long-term durability under pressure.

Is the LSST-01 compliant with ASTM standards?

Yes, the tester is designed to comply with standards such as ASTM F1140, ASTM F2054 etc. for package integrity testing, making it an ideal solution for regulated industries.
