TOPIL Seal-Check™ Vacuum Leak Tester – High-Precision Seal Integrity Testing System for Flexible & Rigid Packaging

Key Features

• Precision Vacuum Control: Digital PLC control allows for adjustable vacuum levels up to -90kPa, ensuring compatibility with various packaging materials.

• Intuitive Visual Testing: The high-transparency acrylic chamber provides a 360∘ view, allowing operators to easily spot bubble emission sites.

• Automatic Test Cycles: Set your target vacuum and hold-time; the machine handles the rest—automatic suction, timing, and pressure release.

• Standardized Compliance: Built to meet and exceed ASTM D3078 (Standard Test Method for Determination of Leaks in Flexible Packaging).

• Non-Destructive Testing: Designed to identify seal failures without damaging the contents (when using dry-test methods), saving product costs.

• Rugged Construction: Features a reinforced, extra-thick acrylic vacuum chamber and a high-performance, oil-free vacuum pump.

Technical Deep-Dive

1. Advanced Leak Detection Technology

The Seal-Check™ utilizes the differential pressure principle. By creating a vacuum in the chamber, the pressure difference causes air inside the package to escape through any seal defects, creating visible bubbles in the water—providing an undeniable visual proof of a failed seal.

2. Digital Intelligent Control

Our latest model replaces outdated analog gauges with a high-precision digital controller.

• Precision: Resolution down to $0.1\text{kPa}$.

• Memory Function: Save multiple test profiles for different product lines (e.g., "Coffee Pouches" vs. "Blister Packs").

• Auto-Calibration: Built-in software ensures the sensor stays accurate over years of use.

3. Industrial-Grade Reliability

As part of our 22-year legacy, we use only premium components. The vacuum seal ring is made of high-rebound silicone that maintains a perfect vacuum even after thousands of test cycles, avoiding the "leakage at the lid" issue common in cheaper models
