NeuronBC Integtest V8.0 Filter Integrity Tester with Full Audit Trail Compliance

Overview

The NeuronBC Integtest V8.0 is a fully validated, GMP-compliant filter integrity tester engineered for quantitative assessment of membrane filter integrity in pharmaceutical, biotechnology, and sterile manufacturing environments. It implements standardized non-destructive test methods—including Forward Flow (FF), Pressure Hold (PH), and Water Intrusion Test (WIT)—in strict accordance with ISO 13408-2, ASTM F838, USP , and EU Annex 1 requirements. The instrument operates on a deterministic, real-time Linux-based embedded platform optimized for reproducible pneumatic control and thermodynamic compensation. Its core architecture integrates high-stability pressure transducers (±0.1% FS accuracy), precision mass flow sensors, and adaptive gas dynamics algorithms to ensure measurement fidelity across variable upstream volumes—up to 100 m of extended gas line length without calibration drift. Designed for both offline benchtop use and online integration into CIP/SIP skids, the V8.0 delivers traceable, ALCOA+–compliant data generation from first power-on through final report export.

Key Features

• FDA 21 CFR Part 11–compliant audit trail system with immutable timestamped logs for all user actions, parameter changes, test executions, and system events
• Four-tier hierarchical user management with customizable role-based permissions, mandatory electronic signatures, and password-protected access levels
• 10-inch capacitive touchscreen interface with bilingual (English/Chinese) navigation, intuitive workflow guidance, and context-sensitive help
• Automated self-diagnostic routine at boot-up and periodic runtime checks covering sensor calibration status, valve actuation response, pressure decay stability, and thermal drift compensation
• Triple-curve real-time visualization: differential pressure vs. time, flow rate vs. time, and diffusion flow vs. applied pressure—exportable as vector-based PDF or CSV
• IP54-rated enclosure with Staubli-compatible quick-connect fittings, dust- and splash-resistant housing, and internal thermal printer using pigment-based thermal paper (10-year legibility guarantee)
• Modular I/O architecture supporting RS232, USB host/device, analog 4–20 mA outputs, and optional Profibus, Modbus TCP, or Wi-Fi modules for MES/SCADA integration

Sample Compatibility & Compliance

The Integtest V8.0 supports integrity testing of hydrophilic and hydrophobic filters ranging from 0.1 µm to 0.45 µm pore size, including cartridge, capsule, and disk formats used in prefiltration, sterilizing-grade, and viral removal applications. It accommodates both single- and multi-stage filter trains, with automatic upstream volume compensation enabled via user-defined geometry inputs or auto-detection via pressure ramp profiling. All test protocols adhere to current regulatory expectations for data integrity: each test record includes raw sensor timestamps, environmental metadata (ambient T/RH), operator ID, electronic signature, and cryptographic hash of the complete dataset. System validation documentation (IQ/OQ/PQ protocols and reports) is provided per client request and aligns with Annex 15 and ASTM E2500 standards.

Software & Data Management

Firmware v8.0 runs on a deterministic real-time Linux kernel with no background services or third-party dependencies—ensuring deterministic execution timing and memory isolation. All test data—including raw sensor streams, interpolated curves, configuration snapshots, and audit logs—are stored in an encrypted SQLite database with SHA-256 checksums. USB export generates ZIP archives containing human-readable HTML reports, machine-readable CSV files (with SI-unit headers), and binary backups for forensic replay. Audit trail entries capture operator login/logout, method selection, parameter edits, manual overrides, calibration events, and firmware updates—with no ability to delete or edit historical entries. Optional cloud sync (via TLS 1.2–secured MQTT) enables centralized log aggregation for enterprise-level review and CAPA linkage.

Applications

• Final filter release testing prior to sterile drug product filling
• In-process verification of vent filter integrity during bioreactor operation
• Post-SIP integrity confirmation for autoclaved filtration systems
• Validation of tangential flow filtration (TFF) cassettes in downstream purification
• Quality control of pre-filters in purified water (PW) and water-for-injection (WFI) distribution loops
• Supporting regulatory submissions requiring full traceability of filter qualification data under ICH Q5A and Q5B

FAQ

Does the Integtest V8.0 support electronic signatures per FDA 21 CFR Part 11?
Yes. It implements role-based digital signatures with dual authentication (password + biometric-ready API), certificate-based signing keys, and non-repudiation logging.
Can test data be exported in formats compatible with LIMS or ELN systems?
Yes. USB export provides CSV (with ISO 8601 timestamps and SI units), PDF/A-2b reports, and structured JSON metadata bundles.
Is the instrument validated for use in Grade A/B cleanroom environments?
The V8.0 meets IP54 ingress protection and has been successfully deployed in ISO Class 5–7 environments; full cleanroom compatibility requires site-specific risk assessment per ISO 14644-1.
How is sensor drift compensated during long-duration pressure hold tests?
The system applies real-time temperature-compensated zero-drift correction using redundant thermal sensors and NIST-traceable pressure transducer characterization tables.
What validation documentation is supplied with the instrument?
Standard delivery includes Factory Acceptance Test (FAT) report, CE Declaration of Conformity, and electronic copies of IQ/OQ templates aligned with ASTM E2500 and GAMP 5.
