Overview
The Labthink C660B Seal Integrity Tester is a precision-engineered vacuum decay-based instrument designed for objective, repeatable assessment of package seal integrity across regulated and high-reliability industries. It operates on the principle of controlled negative pressure application within a sealed water-submerged test chamber—leveraging differential pressure to detect gross leaks, micro-leaks, and structural weaknesses in flexible and rigid packaging systems. When vacuum is applied, defects manifest either as visible gas effervescence from sealed cavities (bubble emission method) or as reversible/irreversible dimensional changes (e.g., expansion and incomplete recovery upon venting), enabling dual-mode pass/fail evaluation per ISO 11607-2, ASTM D3078, and GB/T 15171. Unlike subjective visual inspection or destructive dye penetration, the C660B delivers quantitative, operator-independent results traceable to calibrated vacuum control—making it suitable for validation, routine QC release testing, and post-stress evaluation (e.g., after drop, compression, or thermal cycling).
Key Features
- Multi-mode test methodology: Standard vacuum decay, multi-step graded vacuum profiling, and automated dye-integration mode (replacing manual methylene blue immersion with programmable vacuum-assisted dye ingress timing and dwell control)
- Precision vacuum regulation: High-stability diaphragm vacuum pump and proportional solenoid valve enable ±0.25% full-scale accuracy and 0.1 kPa resolution over 0–90 kPa range
- Real-time graphical monitoring: On-screen dynamic curve display of vacuum level vs. time—including ramp rate, hold stability, and recovery behavior—supports immediate root-cause inference
- Intelligent pass/fail classification: Automated counting of compliant units per batch, with configurable acceptance thresholds based on bubble onset time, expansion magnitude, or recovery kinetics
- Industrial-grade HMI: 7-inch capacitive touchscreen with IP65-rated front panel, one-touch workflow initiation, and firmware-upgradable architecture via Ethernet or USB
- Bilingual interface (English/Chinese) with unit system flexibility (kPa, psi, mbar) and built-in power-loss recovery—retains active test parameters and logged data during unexpected shutdowns
- Local data sovereignty: On-device storage for up to 1,200 standard-test records; optional USB export and thermal printer output (both configurable)
Sample Compatibility & Compliance
The C660B accommodates a broad spectrum of primary and secondary packaging formats without modification: rigid containers (glass, aluminum, PET jars), semi-rigid trays (blister packs, clamshells), flexible pouches (laminated foil, PE/PP coextrusions), tubes (aluminum, laminated plastic), and composite cartons. Its modular vacuum chamber system supports three factory-certified sizes—with custom dimensions available—to ensure full submersion of oversized medical device kits or automotive sensor housings. The system complies with critical regulatory expectations: data audit trails meet FDA 21 CFR Part 11 requirements when paired with optional GMP-compliant software modules; test protocols align with ISO 11607-2 Annex A for sterile barrier systems; and documentation output satisfies EU MDR Annex I essential requirements for leakage verification of Class IIa/IIb devices. All firmware and calibration records are version-controlled and timestamped.
Software & Data Management
When integrated with Labthink’s optional PC-based SealTest Suite, the C660B enables advanced statistical process control (SPC), trend analysis, and electronic batch record generation. The software enforces role-based access control (RBAC) with four-tier user permissions (Operator, Supervisor, QA, Administrator), mandatory electronic signatures for result approval, and immutable test log archiving. Optional DataShield™ integration provides RESTful API connectivity to LIMS, MES, or ERP platforms—enabling automatic metadata ingestion (operator ID, sample ID, lot number, environmental conditions) and centralized dashboard visualization. All raw vacuum-time datasets are stored in vendor-neutral CSV format, supporting third-party statistical review tools (e.g., JMP, Minitab) without proprietary codec dependencies.
Applications
- Pharmaceutical packaging: Sterile vial stopper integrity, blister pack channel seal verification, and pre-filled syringe barrel/cap interface testing
- Medical device packaging: Tyvek®-based pouches, thermoformed trays, and combination products requiring ISO 11607-1 validation
- F&F packaging: Retort pouch seal strength correlation, modified atmosphere packaging (MAP) headspace integrity, and infant formula can seam evaluation
- Electronics: Hermeticity screening of MEMS sensor enclosures, battery module housings, and automotive ECU casings
- Consumer goods: Pen cartridge leak detection, cosmetic tube crimp integrity, and child-resistant closure performance under vacuum stress
FAQ
What vacuum levels does the C660B support, and how is accuracy maintained across the range?
The instrument achieves 0 to –90 kPa (–13 psi) with ±0.25% full-scale accuracy, verified via NIST-traceable pressure transducers and factory calibration at three points (–30, –60, –90 kPa). Drift compensation algorithms adjust for ambient temperature fluctuations during extended hold periods.
Can the C660B be used for quantitative leak rate calculation?
No—it is a qualitative/semi-quantitative pass/fail tester per ASTM D3078 and GB/T 15171. For quantitative flow measurement (e.g., cc/min), Labthink recommends pairing with its VAC-VBS vacuum bubble emission system or complementary helium leak testers.
Is compressed air supply included with the system?
No. Users must provide clean, dry, oil-free compressed air at 0.5–0.7 MPa. The unit features a standardized 6 mm polyurethane tubing interface compatible with common industrial air manifolds.
How does the system support 21 CFR Part 11 compliance?
With optional GMP software add-on, it provides electronic signatures, audit trail logging (including parameter changes and result overrides), and data encryption—fully validated per Annex 11 principles for computerized systems in pharmaceutical manufacturing.
