Overview
The Labthink C660M Pneumatic Burst and Seal Integrity Tester is an engineered solution for quantitative mechanical evaluation of flexible packaging integrity under controlled pressurization. Based on the positive-pressure inflation principle—where regulated compressed air is introduced into sealed packages to induce controlled expansion and eventual failure—the instrument delivers traceable, repeatable measurements of burst pressure, creep behavior, seal strength, and leak integrity. It operates within a defined pneumatic architecture compliant with international standards governing sterile barrier systems (e.g., ISO 11607-1 & -2), pharmaceutical primary packaging (YBB series), and food-grade flexible containers (GB/T 10004, GB 18454). The system’s core function is not merely pass/fail assessment but full parametric characterization: from initial elastic deformation through viscoelastic creep to catastrophic rupture—enabling material scientists, packaging engineers, and QA/QC laboratories to correlate structural design, sealing process parameters (temperature, dwell time, pressure), and substrate composition with functional performance limits.
Key Features
- Multi-mode pneumatic testing: burst test, creep test, creep-to-failure test, and pressure-hold test—each configurable with either restrained (inflation-inhibited) or unrestrained (free-bulge) deformation conditions using optional fixtures.
- Real-time volumetric flow monitoring: proprietary mass-flow sensing technology enables precise control and documentation of gas inflow rates during pressurization, critical for eliminating variability in high-pressure regimes and ensuring inter-laboratory reproducibility per ASTM F2054 Annex A1.
- Industrial-grade capacitive touchscreen interface: intuitive icon-driven workflow with one-touch test initiation, multilingual support (English/Chinese), and dynamic unit switching (kPa, psi, bar, MPa) without software reconfiguration.
- Robust data governance architecture: local storage capacity for ≥1200 test records with automatic timestamping, user ID logging, and power-loss recovery; optional DataShield™ module enables encrypted export, audit trail generation, and integration with LIMS or MES platforms.
- GMP-compliant operation: supports 21 CFR Part 11–aligned electronic signatures, role-based access control (administrator/operator/auditor tiers), and tamper-evident data archiving—validated for pharmaceutical and medical device packaging qualification protocols.
- Modular hardware expandability: standardized Φ8 mm pneumatic interface accommodates external air compressors; interchangeable nozzles (Φ1.6 mm, Φ4 mm, Φ10 mm) and application-specific fixtures (e.g., aerosol valve holders, three-side-seal pouch clamps, tube cradles) extend scope across packaging formats.
Sample Compatibility & Compliance
The C660M accommodates diverse soft packaging geometries—including flat pouches, gusseted bags, stand-up pouches, laminated tubes, blister cavities, and aerosol valve assemblies—without requiring custom tooling for standard configurations. Its mechanical design permits direct mounting of samples onto the test fixture via reusable silicone gaskets or vacuum-assisted clamping. Regulatory alignment includes full traceability to ISO 11607-2 Annex D (burst testing methodology), ASTM F1140 (internal pressurization of non-porous pouches), ASTM F2054 (creep testing under constant pressure), and Chinese pharmacopoeial standards YBB 00162002 and YBB 00252005 for sterile packaging validation. All pressure transducers are factory-calibrated against NIST-traceable references, and calibration certificates are provided with each unit.
Software & Data Management
While the embedded OS handles real-time acquisition and local display, optional PC-based software provides advanced post-processing: overlay of multiple creep curves, statistical analysis (mean, SD, CV%), pass/fail threshold mapping against specification limits, and automated report generation in PDF or CSV format. Audit trails record all user actions—including parameter edits, test aborts, and calibration events—with immutable timestamps. Data export conforms to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), satisfying FDA and EMA expectations for computerized system validation in regulated environments.
Applications
- Flexible packaging: burst strength of retort pouches, peel seal integrity of medical device trays, creep resistance of stand-up coffee bags.
- Tubular packaging: cap-tube detachment force, shoulder seal burst pressure in toothpaste tubes, lamellar weld strength in aluminum-plastic composite tubes.
- Aerosol systems: valve leakage rate at 0.5 MPa, actuator stem seal integrity, crimp retention under cyclic pressure.
- Pharmaceutical blister packs: cavity rupture pressure, foil delamination onset, edge seal robustness under humidity-conditioned testing.
- Food & beverage closures: tamper-evident band torque correlation with burst threshold, liner compression set under sustained pressure, PET bottle neck finish integrity.
FAQ
What pressure ranges does the C660M support?
Standard configuration covers 0–600 kPa (0–87 psi); extended range up to 1.6 MPa (232 psi) is available as a factory-configured option.
Is an air compressor included with the system?
No—the C660M requires an externally supplied clean, dry compressed air source delivering 0.6–0.7 MPa via Φ8 mm polyurethane tubing.
Can test data be exported to LIMS or ERP systems?
Yes—via USB or optional Ethernet interface using structured CSV or XML output; DataShield™ enables secure API-based synchronization with enterprise systems.
Does the instrument meet FDA 21 CFR Part 11 requirements?
When equipped with GMP-compliant firmware, DataShield™, and validated user access controls, it satisfies electronic record and signature requirements for regulated industries.
What maintenance is required for long-term accuracy?
Annual verification of pressure transducer linearity and zero drift against certified reference standards is recommended; Labthink provides accredited calibration services.
