NeuronBC GT-2.0 Online Glove Integrity Tester

Overview

The NeuronBC GT-2.0 Online Glove Integrity Tester is an engineered solution for non-destructive, in-situ leak detection of elastomeric or thermoplastic gloves mounted on isolators, RABS, and gloveboxes used in aseptic pharmaceutical manufacturing and containment environments. It operates on the principle of regulated pressure hold testing—applying a controlled positive pressure differential across the glove surface and monitoring pressure decay over time to quantify leakage rate. This methodology aligns with the physical integrity verification requirements specified in ISO 14644-7:2004 and its national adoption GB/T 25915.7–2010, which define performance criteria for glove systems in cleanroom-associated barrier technology. Unlike destructive bubble tests or qualitative smoke methods, the GT-2.0 delivers quantitative, repeatable pass/fail results traceable to calibrated pressure transducers and temperature-compensated algorithms—enabling objective assessment of glove integrity prior to critical process use.

Key Features

• Integrated pressure regulation architecture with high-stability solenoid valves and dual-range pressure sensors (low-range resolution ≤50 Pa), ensuring precise application and monitoring within the 500–5000 Pa test window.
• Real-time pressure decay analysis with automatic calculation of leakage rate (Pa/min), threshold-based pass/fail classification, and dynamic compensation for ambient temperature drift.
• Role-based user authentication system supporting multi-level operator permissions (e.g., Technician, Supervisor, Administrator), electronic signatures, and tamper-evident audit trail generation—fully compliant with FDA 21 CFR Part 11 requirements when enabled.
• Onboard thermal printer for immediate hard-copy documentation of each test sequence, including timestamp, operator ID, glove ID, pressure curve snapshot, and result status.
• Modular tray interface accommodating up to six independently monitored glove ports per unit; tray geometry and port layout are customizable to match client-specific isolator configurations.
• Robust industrial enclosure rated for continuous operation in controlled environments (ISO Class 5–8); noise emission maintained at ≤50 dB(A) to minimize disruption in GMP-controlled labs.

Sample Compatibility & Compliance

The GT-2.0 is validated for use with standard pharmaceutical-grade gloves—including nitrile, chloroprene, butyl rubber, and multilayer laminates—regardless of thickness (0.15–0.6 mm) or curvature radius. No glove disassembly or external adapters are required; the system interfaces directly with industry-standard glove flanges (e.g., ISO-KF, SMS, or custom-threaded mounts). All firmware logic, data handling routines, and electronic record structures conform to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). The device supports GLP/GMP-aligned validation protocols, including IQ/OQ/PQ documentation packages, and meets the functional expectations of Annex 1 (2022) for barrier system integrity assurance.

Software & Data Management

Embedded firmware provides intuitive touch-screen navigation with multilingual UI (English, Chinese, Spanish). Test parameters—including target pressure, hold duration, acceptance thresholds, and calibration offsets—are configurable via secure admin login. All raw pressure-time datasets, metadata, and operator actions are stored locally in encrypted binary format with cyclic overwrite protection (≥10,000 records retained). Optional USB export enables CSV-formatted data transfer for external statistical process control (SPC) analysis or LIMS integration. Audit trail logs capture event type, timestamp, user ID, IP address (if network-enabled), and pre-/post-change values—retained separately from operational data to preserve evidential integrity during regulatory inspection.

Applications

• Routine pre-use verification of isolator gloves prior to aseptic filling, lyophilization, or potent compound handling.
• Periodic requalification of glove integrity following cleaning cycles, sterilization (VHP, steam), or mechanical stress events.
• Root cause investigation during environmental monitoring excursions where glove breach is suspected.
• Supporting Annex 1-mandated risk-based qualification of barrier systems in Category 3 and 4 manufacturing facilities.
• Integration into automated facility monitoring networks via optional Modbus TCP or OPC UA gateways (hardware-dependent).

FAQ

What pressure sources are compatible with the GT-2.0?

Compressed air, nitrogen, or other inert gases meeting ISO 8573-1 Class 2:2:2 purity specifications may be used—provided inlet pressure remains stable between 0.6–0.8 MPa and contains no liquid condensate or particulates.
Can the GT-2.0 validate gloves after autoclaving or vaporized hydrogen peroxide (VHP) treatment?

Yes—provided gloves are fully dried and cooled to ambient temperature prior to testing; residual moisture or thermal expansion artifacts are mitigated by the instrument’s built-in stabilization delay and temperature compensation algorithm.
Is third-party calibration certification available?

NeuronBC provides NIST-traceable calibration certificates for pressure sensors and timing modules upon request; annual recalibration services include full functional verification against ISO 14644-7 Annex B reference procedures.
How is data integrity ensured during power interruption?

Non-volatile flash memory preserves all active test sessions and audit logs during unexpected shutdown; the system resumes operation without data loss and timestamps recovery events in the audit trail.
Does the GT-2.0 support 21 CFR Part 11 compliance out-of-the-box?

Core electronic signature and audit trail functions are embedded in firmware; full Part 11 compliance requires site-specific configuration of password policies, session timeouts, and digital certificate management—documented in the included Validation Support Package.
