ATC ME2 Pharmaceutical Container Closure Integrity Tester (CCIT)

Overview

The ATC ME2 is a fully automated, non-destructive Container Closure Integrity Tester (CCIT) engineered for high-reliability detection of micron-scale leaks in sterile pharmaceutical primary packaging. It implements the Mass Extraction Method (MEM), a gravimetric vacuum-based technique standardized in ASTM F3287–17 and aligned with USP guidance on deterministic leak testing. Unlike probabilistic methods such as dye ingress or microbial challenge, MEM quantifies real-time mass loss (in µg/min) under controlled vacuum conditions, enabling objective, traceable, and repeatable pass/fail determinations. The system is designed for integration into development labs, QC release testing environments, and stability study workflows—supporting regulatory submissions requiring data integrity, audit trails, and method validation per ICH Q5A(R2), FDA 21 CFR Part 11, and EU Annex 1 requirements for aseptic processing.

Key Features

• Vacuum-driven mass extraction architecture delivering ≥1 µm equivalent leak sensitivity for glass and polymer containers
• Temperature-compensated transducer array ensuring measurement stability across ambient lab conditions (15–30 °C)
• Modular test chamber design accommodating vials (2–50 mL), ampoules, pre-filled syringes, cartridges, blow-fill-seal (BFS) units, and IV bags without mechanical reconfiguration
• Integrated Leak-RX software platform compliant with FDA 21 CFR Part 11—including electronic signatures, role-based access control, and immutable audit trails
• Automated IQ/OQ documentation package supporting GMP-compliant installation and operational qualification
• Full method validation support: precision, accuracy, specificity, robustness, and limit of detection (LOD) assessment per ICH Q2(R2)

Sample Compatibility & Compliance

The ME2 validates integrity across diverse fill formats—including aqueous solutions, lyophilized powders, suspensions, and oil-based formulations—without interference from headspace gas composition or internal pressure differentials. It meets ASTM F3287–17 requirements for quantitative leakage rate reporting and supports compliance with ISO 11607-1/2 (packaging validation), USP (deterministic test selection), and EMA CHMP/Q5A(R2) guidelines on viral clearance and container-closure system qualification. All test protocols are preconfigured to align with GLP/GMP data governance standards, including ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Software & Data Management

Leak-RX v4.2 provides full lifecycle data management: method creation, batch-level test sequencing, real-time trend visualization, statistical process control (SPC) charting, and automated report generation (PDF/CSV). Raw sensor data—including vacuum ramp profiles, mass loss curves, and environmental metadata (temperature, barometric pressure)—are stored in encrypted SQLite databases with SHA-256 hashing. System validation includes embedded electronic signature workflows, user authentication via LDAP/Active Directory, and configurable retention policies meeting 21 CFR Part 11 Subpart B §11.10 and §11.30 requirements. Audit logs record every action—including parameter edits, result overrides, and export events—with timestamps and operator IDs.

Applications

• Development-stage container-closure system qualification during formulation and packaging design
• Process validation of sealing operations (e.g., crimping, stoppering, laser welding)
• Stability protocol execution per ICH Q1–Q5, including accelerated and long-term storage condition monitoring
• In-process quality checks during commercial manufacturing campaigns
• Root cause analysis of sterility failures through correlation with MEM-derived leak rates
• Regulatory submission support: CCIT data packages for ANDA, BLA, and MAA filings

FAQ

Does the ME2 require calibration with certified leak standards?
Yes—annual calibration using NIST-traceable calibrated leak devices (1–10 µm equivalent orifice) is recommended and supported by ATC’s certified service network.
Can the system detect leaks in frozen or refrigerated samples?
The ME2 operates at ambient temperature; samples must be equilibrated to room temperature prior to testing to ensure consistent vapor pressure and avoid condensation artifacts.
Is method transfer between ME2 instruments feasible?
Yes—Leak-RX supports standardized method export/import, and inter-instrument reproducibility is verified per ASTM F3287 Annex A2 using reference samples.
What sample preparation is required before testing?
No sample modification is needed; intact, commercially filled units are loaded directly into the chamber after visual inspection for gross damage.
How does MEM compare to helium leak testing?
MEM offers comparable sensitivity (≥1 µm) without requiring helium charging, vacuum chambers, or specialized gas handling infrastructure—reducing operational complexity and cost of ownership.
