NeuronBC BGT-120 Bag Integrity Tester

Overview

The NeuronBC BGT-120 Bag Integrity Tester is a compact, portable pressure decay-based integrity verification system engineered for non-destructive, quantitative assessment of sealed flexible pharmaceutical packaging—specifically single-use bioprocess bags, fluid containment bags, and sterile transfer containers used in upstream and downstream biomanufacturing. It operates on the principle of controlled pressurization followed by high-resolution monitoring of pressure decay over time, in strict accordance with ASTM F2095-01 “Standard Test Method for Determining Integrity of Seals in Flexible Barrier Materials Using Pressure Decay.” This method quantifies leakage rates by measuring the rate of pressure loss under defined conditions, enabling detection of defects as small as sub-10 µm channels or micro-leaks at seal interfaces. Designed for integration into GMP-compliant environments, the BGT-120 supports lifecycle validation activities—including Installation Qualification (IQ), Operational Qualification (OQ), Performance Qualification (PQ), and Standard Operating Procedure (SOP) documentation—and delivers traceable, auditable results aligned with regulatory expectations for single-use system qualification.

Key Features

• High-resolution pressure sensing with 0.1 Pa resolution and ≤50 Pa response threshold, ensuring sensitivity to minute pressure deviations indicative of micro-leakage.
• Intelligent gas dosing algorithm that employs low-volume, frequent pneumatic pulses—minimizing transient bag deformation and preventing false-negative outcomes caused by elastic relaxation or creep effects.
• 7-inch full-color capacitive touchscreen interface with intuitive navigation, real-time graphical pressure curve display, and auto-adaptive test protocol selection based on user-defined bag volume, material compliance, and target leak threshold.
• Built-in rechargeable lithium-ion battery enabling field-deployable operation without mains dependency—ideal for cleanroom mobile use, cross-facility audits, or manufacturing suite walkdowns.
• Integrated thermal printer for immediate hard-copy generation of test reports, including timestamp, operator ID, test parameters, raw pressure decay data, pass/fail verdict, and digital signature confirmation.
• Role-based access control with configurable user permissions, electronic signatures, and optional 21 CFR Part 11-compliant audit trail module supporting GLP/GMP-regulated workflows.

Sample Compatibility & Compliance

The BGT-120 is validated for use with standard single-use bioprocess bags ranging from 1 L to 2000 L capacity, fabricated from multi-layer ethylene vinyl acetate (EVA), polyolefin, or thermoplastic polyurethane (TPU) films. It accommodates both flat-bottom and gusseted configurations, provided the bag includes a dedicated pressure port or compatible septum-sealed inlet. The instrument meets essential requirements of ISO 11607-2 (Packaging for terminally sterilized medical devices), aligns with USP guidance on package integrity evaluation, and supports risk-based validation strategies per ICH Q5C and Annex 1 (2022). Its pressure decay methodology avoids contact with product-contact surfaces, eliminating contamination risk and preserving sterility assurance during testing.

Software & Data Management

Firmware v3.2+ provides local storage of ≥10,000 complete test records—including pressure vs. time datasets, environmental metadata (ambient temperature/humidity), operator credentials, and pass/fail logic flags. Data export is supported via USB 2.0 to CSV or PDF formats, with optional Ethernet/Wi-Fi connectivity for integration into LIMS or MES platforms. All electronic records incorporate cryptographic hashing and immutable timestamps. When equipped with the audit trail option, the system logs every configuration change, user login/logout event, report generation, and parameter modification—fully satisfying FDA 21 CFR Part 11 Subpart B requirements for electronic record retention and signature attribution.

Applications

• Pre-use qualification of single-use bioreactor bags, harvest bags, and buffer storage containers.
• Post-sterilization integrity verification following gamma or E-beam irradiation.
• In-process leak screening during assembly line integration of tubing welds, filter housings, and connector interfaces.
• Root cause analysis of seal failures in stability studies or deviation investigations.
• Supplier qualification and incoming inspection of pre-sterilized bag lots.
• Supporting Annex 1 (2022) requirement for “continuous verification” of container-closure integrity in aseptic processing.

FAQ

What gases are compatible with the BGT-120 for pressurization?

Compressed air, nitrogen, or other inert process gases with dew point ≤ −40 °C and oil-free filtration (ISO 8573-1 Class 1:4:1) are recommended.
Does the BGT-120 require external calibration services?

No routine external calibration is required; the integrated pressure transducer is factory-calibrated against NIST-traceable standards, with user-performed zero-point verification supported via software menu.
Can test methods be customized for non-standard bag geometries?

Yes—users may define custom test profiles including ramp rate, hold duration, decay window, and pass/fail thresholds via the advanced settings menu.
Is the device suitable for use inside Grade A/B cleanrooms?

Yes—the unit meets IP54 ingress protection rating, features smooth non-porous housing, and generates <50 dB(A) acoustic noise, complying with EU GMP Annex 1 environmental constraints.
How is data backup and recovery managed?

Test records are automatically mirrored to internal flash memory and removable USB storage; firmware supports scheduled automated backup and encrypted archive export.
