NeuronBC BGT-100 Single-Use Bioreactor Bag Integrity Tester

Overview

The NeuronBC BGT-100 Single-Use Bioreactor Bag Integrity Tester is an engineered solution for non-destructive, quantitative verification of seal and membrane integrity in single-use bioprocessing containers—primarily pre-sterilized, gamma-irradiated bioreactor bags, fluid bags, and tubing assemblies used in upstream and downstream biomanufacturing. It implements the pressure decay method in strict accordance with ASTM F2095-01, “Standard Test Methods for Detecting Gross Leaks in Packaging by Pressure Decay,” a scientifically validated and industry-accepted protocol for leak detection in flexible, low-permeability barrier systems. Unlike bubble emission or dye ingress tests, pressure decay quantifies minute pressure loss over time under controlled, isothermal conditions—enabling high reproducibility, operator-independent results, and traceable pass/fail determination without compromising sterility or bag functionality. The BGT-100 is designed for routine use in GMP-compliant environments where regulatory accountability, data integrity, and process validation are mandatory.

Key Features

• Compliant pressure decay methodology per ASTM F2095-01, supporting ICH Q5A, USP <1207>, and Annex 1-aligned risk-based integrity assessment strategies
• High-resolution pressure sensing with 0.1 Pa resolution and ≤50 Pa system response threshold, ensuring sensitivity to leaks equivalent to ≤1 µm equivalent hole diameter under standard test conditions
• Intelligent gas delivery control: micro-pulsed inflation algorithm minimizes transient stress on bag geometry, preventing false positives due to elastic deformation or creep
• 7-inch color capacitive touchscreen interface with intuitive workflow navigation, real-time pressure curve visualization, and automatic parameter adaptation based on bag volume and material compliance
• Built-in thermal printer for immediate hard-copy documentation of test ID, timestamp, pressure profile, result status (“Pass”/“Fail”), and operator signature
• Role-based access control with configurable user permissions, electronic signatures, and optional 21 CFR Part 11-compliant audit trail module for full data provenance
• Compact benchtop footprint (370 × 220 × 210 mm) and lightweight design (4.5 kg) enable deployment across QC labs, cleanroom anterooms, and manufacturing support areas

Sample Compatibility & Compliance

The BGT-100 is validated for use with commercially available single-use bioreactor bags ranging from 5 L to 2000 L nominal volume, including those fabricated from multi-layer ethylene vinyl acetate (EVA), polyolefin, and thermoplastic polyurethane (TPU) films. It accommodates standard bag port configurations (e.g., 3/8″ or 1/2″ sanitary fittings) via adaptable quick-connect couplings. All test methods and system configurations adhere to current Good Manufacturing Practice (cGMP) requirements as defined in FDA 21 CFR Parts 210/211 and EMA Annex 1. Instrument qualification packages—including Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ)—are provided, along with standardized operating procedures (SOPs) and risk assessments aligned with ISO 14644-1 (cleanroom classification) and ISO 9001 quality management frameworks.

Software & Data Management

Data acquisition, analysis, and archival are managed through embedded firmware compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Each test record includes metadata such as operator ID, bag lot number, test date/time, environmental temperature, applied pressure setpoint, decay slope, calculated leak rate, and final verdict. Up to 10,000 test records are retained locally with timestamped indexing. Export options include CSV files via USB port for integration into LIMS or ELN platforms. When equipped with the optional audit trail module, all user actions—including parameter edits, result overrides, and login/logout events—are immutably logged with digital timestamps and cryptographic hashing to satisfy FDA 21 CFR Part 11 and EU Annex 11 electronic record requirements.

Applications

• Pre-use integrity verification of single-use bioreactors prior to cell culture inoculation
• Post-sterilization (gamma/e-beam) integrity confirmation of sealed bags and fluid pathways
• In-process monitoring during transportation or storage under controlled ambient conditions
• Root cause investigation of batch failures linked to potential container breach events
• Supporting comparability protocols during technology transfer or scale-up activities
• Qualification of new bag suppliers or alternative film formulations against legacy specifications

FAQ

What gas sources are compatible with the BGT-100?
Compressed air, nitrogen, or other inert gases may be used, provided inlet pressure does not exceed 0.5 MPa and gas is filtered to ≤0.01 µm to prevent sensor contamination.

Is external calibration required?
The instrument includes factory-calibrated pressure transducers traceable to NIST standards; annual recalibration is recommended and supported by certified service partners.

Can the BGT-100 validate bags larger than 2000 L?
While optimized for standard bioreactor sizes up to 2000 L, extended testing protocols for ultra-large bags (e.g., 5000 L) can be implemented under PQ guidance with adjusted stabilization times and decay thresholds.

Does the system support network connectivity or remote monitoring?
The base model operates as a standalone unit; Ethernet or Wi-Fi modules are available as custom OEM integrations upon request for centralized fleet management.

How is operator training delivered?
On-site installation, operational training, and IQ/OQ execution are included in standard delivery; refresher courses and SOP development support are offered annually.
