Labthink MFY-01 Container Seal Integrity Tester

Overview

The Labthink MFY-01 Container Seal Integrity Tester is an engineered solution for quantitative and qualitative assessment of package seal integrity across rigid and semi-rigid containers—including PET water bottles, pharmaceutical blister packs, HDPE/PP jars, aluminum cans, and composite tubes. It operates on the internationally recognized vacuum decay and submerged bubble emission principles defined in ASTM D3078 and GB/T 15171. During testing, the specimen is placed inside a sealed vacuum chamber partially filled with deionized water; a controlled negative pressure is applied to induce differential pressure across the container wall or seal interface. Two distinct pass/fail evaluation modes are supported: (1) visual observation of air leakage via sustained bubble streams from compromised seals or microchannels, and (2) deformation-based assessment—monitoring container expansion under vacuum and subsequent shape recovery upon pressure release—to detect elastic seal failure or material creep not evident via bubble emission alone. This dual-mode capability ensures robust detection of both gross leaks (>100 µm equivalent orifice) and subtle defects affecting long-term barrier performance.

Key Features

• Digital preset vacuum setpoint and hold time control—enabling repeatable test conditions per ISO/IEC 17025 traceability requirements
• High-reliability pneumatic components sourced from globally certified suppliers, ensuring long-term stability and minimal maintenance
• Microprocessor-controlled automatic pressure compensation system maintains constant vacuum level during test duration, mitigating drift-induced false negatives
• Integrated software-driven auto-depressurization and test termination sequence—eliminating manual intervention and reducing operator variability
• Backlit LCD interface with intuitive PVC membrane keypad for rapid parameter entry, real-time status monitoring, and on-device result review
• Modular chamber design supporting three standard internal volumes (with custom dimensions available upon request) to accommodate diverse container geometries—from single-dose vials to 2L beverage bottles

Sample Compatibility & Compliance

The MFY-01 accommodates a broad spectrum of packaging formats used in regulated and non-regulated industries: sterile medical device pouches, child-resistant pharmaceutical containers, food-grade PET bottles, aerosol cans, cosmetic tubes, and automotive fluid reservoirs. Its methodology aligns with critical quality assurance frameworks—including FDA Guidance for Industry on Container Closure Integrity Testing (CCIT), USP , and ISO 11607-2. While primarily deployed for routine QC screening, the instrument’s deterministic physical output (bubble count, expansion magnitude, recovery lag) supports root cause analysis when integrated with statistical process control (SPC) protocols. All hardware and firmware comply with CE marking directives (2014/30/EU EMC, 2014/35/EU LVD), and the system architecture permits audit-ready documentation when paired with Labthink’s optional 21 CFR Part 11-compliant software module.

Software & Data Management

The embedded control firmware logs timestamped vacuum profiles, dwell times, and operator IDs for each test cycle. Optional PC-based Labthink TestSuite™ software enables export of raw data to CSV or PDF, generation of compliance reports aligned with GLP/GMP documentation standards, and integration into enterprise LIMS environments via configurable API endpoints. Audit trails record all parameter modifications, user logins, and test outcomes with immutable timestamps—fully satisfying FDA 21 CFR Part 11 electronic record requirements when enabled. Data encryption at rest and role-based access control further support secure deployment in shared laboratory infrastructures.

Applications

• Verification of heat-seal integrity in laminated pouches post-form-fill-seal (FFS) processing
• Post-sterilization validation of Tyvek®-lidded trays used in Class 100 cleanrooms
• Leak screening of blow-molded PET water bottles following drop impact or compression testing per ISTA 3A
• QC release testing for ophthalmic solution dropper bottles subject to USP
• Evaluation of adhesive bond strength in multi-layer tube bodies under simulated shelf-life vacuum conditions
• Failure mode analysis of crimped aluminum closures on glass vials exposed to thermal cycling

FAQ

What types of containers can be tested with the MFY-01?
Rigid and semi-rigid containers including PET, HDPE, PP, glass, aluminum, and composite materials—provided they maintain structural integrity under vacuum and do not deform irreversibly.
Is compressed air supply included with the instrument?
No. A clean, dry, oil-free air source delivering 0.7 MPa (100 psi) through a Φ6 mm polyurethane tube is required and must be provided by the user.
Does the MFY-01 meet regulatory requirements for pharmaceutical packaging validation?
Yes—when operated per ASTM D3078 and coupled with documented SOPs, it satisfies initial CCIT verification per USP . For fully validated applications, integration with 21 CFR Part 11 software and IQ/OQ/PQ protocols is recommended.
Can test parameters be saved as reusable methods?
Yes. Up to 20 user-defined test configurations—including vacuum level, hold time, and chamber ID—can be stored and recalled directly from the front panel.
What maintenance is required for long-term accuracy?
Annual calibration of the vacuum transducer against NIST-traceable reference standards is advised; routine cleaning of the chamber gasket and water bath is sufficient for daily operation.
