Overview
The Labthink C690B Vacuum Decay Leak Tester is an engineered solution for quantitative, non-destructive package integrity verification based on the vacuum decay principle—a deterministic physical method recognized in ASTM F2338–22, USP , and YY/T 0681.18. Unlike subjective dye ingress or bubble emission tests, this instrument measures minute pressure differentials within a sealed test chamber to calculate leakage rates with traceable metrological rigor. It operates by evacuating a calibrated chamber containing the test sample to a user-defined vacuum level, then monitoring real-time pressure recovery over time using high-stability piezoresistive sensors. The resulting decay curve is mathematically modeled to derive equivalent leak orifice size (in µm), enabling objective pass/fail decisions aligned with regulatory thresholds for sterile and aseptic packaging.
Key Features
- Vacuum decay methodology compliant with ASTM F2338–22, USP Category 3 (Deterministic, Quantitative), and ISO 11607–2 Annex D
- User-configurable vacuum setpoint from –100 kPa to 0 kPa, supporting diverse container geometries and material compliance requirements
- High-resolution pressure transducer with ±1 µm repeatability and 0.1 µm resolution—traceable to NIST-certified calibration standards
- Integrated micro-flow control system enabling precise simulation of reference leaks without manual valve adjustment or external flow restrictors
- 12.1-inch industrial-grade capacitive touchscreen with flat-layout GUI; real-time pressure curve visualization and automatic statistical reporting per test cycle
- Onboard data logging with timestamped records, power-loss recovery, and USB export capability; optional integrated thermal printer for immediate hardcopy output
- GMP-ready architecture featuring multi-level user permissions, electronic signatures compliant with FDA 21 CFR Part 11 (when configured), and full audit trail generation
Sample Compatibility & Compliance
The C690B accommodates rigid and semi-rigid primary packaging formats up to Ø45 mm × 80 mm—including vials (e.g., serum, lyophilized, and pre-filled syringes), ampoules, cartridge vials (cartridge systems), IV bags (with rigid ports), and food-grade containers (e.g., PET bottles, aluminum cans, and laminated pouches). Its dry, non-invasive operation eliminates solvent exposure, residue risk, or post-test handling contamination—critical for sterility assurance. All firmware and software modules support ALCOA+ data integrity principles. Validation documentation packages—including IQ/OQ/PQ protocols, uncertainty budgets, and method suitability reports—are available to support GLP/GMP audits and regulatory submissions (e.g., FDA BLA/MAA, EMA Annex 1 alignment).
Software & Data Management
Labthink’s proprietary TestMaster™ software provides full lifecycle data governance: automated calculation of leak rate (std cm³/s), equivalent hole diameter (µm), and confidence intervals; batch-level trending via Levey-Jennings charts; and CSV/PDF export with embedded metadata (operator ID, timestamp, environmental conditions, calibration status). When deployed with optional GMP-compliant computer systems, the platform enforces role-based access control, electronic signature workflows, and immutable audit trails meeting 21 CFR Part 11 Subpart B requirements—including record retention, electronic record authentication, and system validation documentation. Raw sensor data and processed results are stored in encrypted SQLite databases with SHA-256 hashing for forensic traceability.
Applications
- Pharmaceutical quality control: Routine testing of lyophilized vial stopper integrity, pre-filled syringe plunger seal verification, and ampoule tip seal assessment prior to sterilization release
- Biologics and cell/gene therapy packaging: Detection of sub-3 µm defects in single-use bioreactor bags and cryovials where microbial ingress risk must be quantified below ISO 11607–2 acceptance limits
- FDA-mandated container closure integrity testing (CCIT): Supporting validation of alternative methods per USP for Level 1–3 risk classifications
- Food safety compliance: Verification of hermetic seals in retort pouches, canned goods, and modified atmosphere packaging (MAP) under shelf-life stability programs
- Method transfer and comparability studies: Bridging vacuum decay data with helium mass spectrometry or laser-based headspace analysis for cross-platform correlation
FAQ
What regulatory standards does the C690B comply with?
ASTM F2338–22, USP , YY/T 0681.18, ISO 11607–2, and EU Annex 1 requirements for deterministic CCIT.
Can the system be validated for GMP use?
Yes—full IQ/OQ/PQ documentation, calibration certificates traceable to NIST, and 21 CFR Part 11 configuration options are available.
Is compressed air required for operation?
Yes—clean, oil-free compressed air at ≥500 kPa (72.5 PSI) is needed for vacuum pump cooling and actuation; source must meet ISO 8573–1 Class 2 purity.
What is the smallest detectable leak size?
The instrument achieves ≤3 µm equivalent orifice detection (per USP reference standard), with resolution down to 0.1 µm and repeatability of ±1 µm.
Does the system support custom test chamber designs?
Yes—Labthink offers application-specific chamber engineering, including positive/negative control reference samples and fixture adaptation for non-standard container geometries.
