Labthink C660M Intelligent Positive-Pressure Seal Integrity Tester

Overview

The Labthink C660M Intelligent Positive-Pressure Seal Integrity Tester is an engineered solution for quantitative assessment of seal integrity, burst resistance, creep behavior, and mechanical strength in flexible packaging, closures, and dispensing systems. It operates on the principle of controlled pressurization—introducing regulated compressed air into sealed specimens while continuously monitoring internal pressure, inflation flow rate, and time-dependent deformation responses. Unlike vacuum-based leakage detection methods, the positive-pressure approach directly simulates real-world mechanical stress conditions such as stacking, transportation vibration, thermal expansion, and consumer handling forces. The system is calibrated to deliver traceable, repeatable measurements under defined test protocols aligned with international regulatory frameworks governing sterile barrier systems (e.g., ISO 11607-1/-2), pharmaceutical primary packaging (USP ), and food contact materials (GB/T 10004, GB 18454). Its architecture supports both destructive (burst) and non-destructive (creep, hold) evaluation modes, enabling comprehensive failure mode analysis across diverse material configurations—from multilayer laminates to aluminum-plastic blister foils and polypropylene screw caps.

Key Features

• Multi-mode testing capability: burst pressure, creep test, creep-to-failure, and pressure-hold protocols—each configurable with independent setpoints for pressure ramp rate, target pressure, hold duration, and pass/fail thresholds
• Real-time airflow monitoring via proprietary mass-flow sensor technology—enabling precise control and documentation of gas ingress kinetics during pressurization, critical for distinguishing true seal failure from elastic expansion artifacts
• Industrial-grade 7-inch capacitive touchscreen interface with intuitive icon-driven navigation, multi-language support (English/Chinese), and fully customizable test templates
• Embedded data management: 1200-test local storage capacity, automatic timestamping, user ID logging, and audit-trail generation compliant with GLP/GMP requirements when paired with optional DataShield™ software
• Modular hardware design: interchangeable inflation nozzles (Φ1.6 mm, Φ4 mm, Φ10 mm), optional high-pressure upgrade kit (up to 1.6 MPa), and auxiliary fixtures for specialized applications including aerosol valve testing and three-side-sealed pouch evaluation
• Electrical and pneumatic safety compliance: integrated pressure relief valve, overpressure cutoff, and dual-channel pressure transducer redundancy ensuring operational integrity within Class I, Division 2 hazardous location guidelines

Sample Compatibility & Compliance

The C660M accommodates a broad spectrum of package geometries and closure types without requiring custom tooling. Standard test fixtures accept flat pouches (up to 300 × 400 mm), cylindrical containers (diameter ≤120 mm), collapsible tubes (diameter ≤45 mm), and threaded closures (cap diameter ≤80 mm). It meets essential regulatory benchmarks including ISO 11607-2 Annex B (leak test validation), ASTM F1140 (internal pressurization of flexible packages), and YBB 00252005 (plastic cap sealing performance for pharmaceuticals). When configured with GMP-compliant firmware and DataShield™ integration, the instrument satisfies FDA 21 CFR Part 11 requirements for electronic records and signatures—including role-based access control, biometric or password authentication, and immutable event logs. All pressure sensors are NIST-traceable and recalibration intervals follow ISO/IEC 17025 recommendations.

Software & Data Management

The C660M operates autonomously but integrates seamlessly with Labthink’s optional SealTest Pro software suite for advanced statistical process control (SPC), trend analysis, and cross-instrument data aggregation. Raw test data—including pressure vs. time curves, flow-rate profiles, and failure classification tags—are exported in CSV, PDF, or XML formats compatible with LIMS and MES platforms. The embedded DataShield™ module enables encrypted cloud synchronization, remote diagnostics, and centralized calibration status tracking across enterprise-wide instrument fleets. Audit trails capture operator actions, parameter changes, and environmental deviations (e.g., ambient temperature shifts >±2°C), supporting full 21 CFR Part 11 compliance when deployed in regulated manufacturing environments.

Applications

• Plastic防盗 caps: quantification of tamper-evident band retention force, thread engagement integrity, and seal gasket compression resilience under static and dynamic pressure loads
• Flexible pouches: determination of peel-initiated burst pressure, edge seal delamination onset, and laminate layer separation thresholds per GB/T 10440 and ASTM F2054
• Tubes: evaluation of crimp seal integrity, nozzle weld strength, and body-wall collapse resistance under axial loading conditions
• Blister packs: detection of foil-punch delamination, cavity wall fracture, and channel seal leakage in thermoformed PVC/PVDC structures
• Aerosol actuators: verification of valve stem seating integrity, dip tube seal robustness, and metering chamber leak rates at operating pressures up to 0.8 MPa
• Three-side-sealed bags: assessment of heat-seal uniformity, cold seal adhesion stability, and corner stress concentration effects during pressurization

FAQ

What pressure ranges does the C660M support out-of-the-box?
The standard configuration covers 0–600 kPa (0–87 psi); a factory-installed high-pressure option extends the range to 0–1.6 MPa (0–232 psi) with recalibrated transducers and reinforced sealing components.
Is compressed air supply included with the instrument?
No—the C660M requires an external clean, dry, oil-free air source delivering 0.6–0.7 MPa (87–101 psi) via Φ8 mm polyurethane tubing; laboratory-grade compressors or nitrogen generators are recommended.
Can test results be exported to Excel or LIMS systems?
Yes—via USB port or optional Ethernet/Wi-Fi module, raw datasets and summary reports export in CSV, PDF/A-2, or structured XML format, with metadata fields mapped to ASTM E1461 and ISO/IEC 11179 standards.
Does the system meet FDA 21 CFR Part 11 requirements?
When equipped with GMP-compliant firmware, DataShield™, and validated user access controls, the C660M fulfills electronic record and signature criteria—including audit trail generation, electronic signatures, and system validation documentation support.
What maintenance is required for long-term accuracy?
Annual calibration of pressure transducers and flow sensors against NIST-traceable references is recommended; routine verification using certified reference standards (e.g., dead-weight testers) should occur before each shift in regulated environments.
