Labonce Labonce-8000GS Walk-in Stability Chamber for Pharmaceutical Testing

Overview

The Labonce Labonce-8000GS Walk-in Stability Chamber is an engineered environmental test system designed specifically for long-term, real-time stability studies of pharmaceutical products in accordance with ICH Q1A(R3), Q5C, and regulatory requirements outlined in the Chinese Pharmacopoeia (2020 Edition) and USP . It operates on a precision-controlled forced-air convection principle, utilizing a dual-loop temperature and humidity regulation architecture to maintain highly reproducible conditions across its 8,000-liter internal volume. Unlike benchtop chambers, the Labonce-8000GS integrates validated uniformity performance—demonstrated via mapping per ISO 14644-3 and ASTM E2297—into a walk-in configuration, enabling simultaneous storage and monitoring of multiple batches, reference standards, and accelerated stress samples under GxP-aligned operational parameters.

Key Features

• Stainless steel 304 interior chamber and airflow ducting, corrosion-resistant and compliant with cleanroom-grade surface finish requirements
• Redundant refrigeration system with imported hermetic compressors and optional variable-frequency drive (VFD) for ≥50% energy reduction during low-load operation
• Capacitive humidity sensor (imported, factory-calibrated) with drift <0.5% RH/year and no routine recalibration required
• 7-inch industrial-grade color touchscreen controller supporting multi-step programmable profiles, real-time trend graphs, and configurable alarm thresholds
• Triple-tier user authentication (Operator / Supervisor / Administrator) with role-based permissions and encrypted login audit logs
• Comprehensive safety suite: mechanical keyed door lock with anti-jamming mechanism, internal emergency release button, thermal cutoffs, and integrated water-level detection
• Dual independent temperature/humidity monitoring probes installed at spatially validated worst-case locations (per IQ/OQ protocols)
• Onboard micro-printer for immediate hard-copy record generation; internal flash memory stores ≥12 months of 1-minute interval data

Sample Compatibility & Compliance

The Labonce-8000GS accommodates diverse pharmaceutical dosage forms—including tablets, capsules, injectables, lyophilized powders, and biologics—within standardized ICH storage conditions (e.g., 25°C/60% RH, 30°C/65% RH, 40°C/25% RH). Its design supports both long-term (25°C/60% RH) and intermediate (30°C/65% RH) stability testing per ICH Q5C. Optional low-temperature configurations (2–8°C or ≤20°C) enable concurrent cold-chain validation studies. All control logic, data handling, and user interaction pathways comply with ALCOA+ principles. The system meets traceability requirements for GLP and GDP environments and can be fully qualified (IQ/OQ/PQ) per Annex 15 and WHO TRS 992. Optional network server integration provides centralized fleet management and satisfies FDA 21 CFR Part 11 electronic record/electronic signature (ERES) criteria when deployed with time-stamped, immutable audit trails.

Software & Data Management

The embedded controller firmware records all operational events—including setpoint changes, alarm activations, door openings, and calibration interventions—with timestamps, user IDs, and contextual metadata. Audit trail entries are write-once, non-erasable, and exportable via USB to CSV or PDF formats with digital signature verification. Data retention exceeds 12 months at 1-minute logging intervals without external storage dependency. Optional Ethernet-enabled gateway modules support secure HTTPS-based remote monitoring, automated report generation (PDF/Excel), and integration into LIMS or MES platforms using RESTful APIs. All exported files include cryptographic hash verification to ensure data integrity during transfer and archival.

Applications

• ICH-compliant stability protocol execution for new drug applications (NDAs), abbreviated new drug applications (ANDAs), and marketing authorization applications (MAAs)
• Real-time and accelerated stability studies per ICH Q1A(R3), Q1B, and Q5C guidelines
• Reference standard storage under controlled conditions meeting USP and Ph. Eur. 2.2.48 requirements
• Excipient compatibility screening and formulation robustness assessment
• Process validation support for packaging integrity (e.g., blister seal strength under humidity stress)
• GMP warehouse environmental qualification and ongoing monitoring (per EU GMP Annex 15)

FAQ

Does the Labonce-8000GS support FDA 21 CFR Part 11 compliance?
Yes—when configured with the optional network server module and enabled audit trail settings, the system meets electronic record and electronic signature requirements including role-based access control, audit trail review capability, and non-erasable data export.
Can the chamber be validated for GMP use?
Yes—the Labonce-8000GS is supplied with full qualification documentation templates (IQ/OQ/PQ), mapping protocols, and calibration certificates traceable to NIST standards. Installation includes on-site temperature/humidity uniformity mapping per ISO 14644-3.
What is the minimum temperature achievable in the optional low-temperature configuration?
The system supports custom configurations down to 2°C ±1.0°C (refrigerated storage) or ≤20°C (cool storage), with independent validation reports available upon request.
Is remote monitoring supported out of the box?
Remote monitoring requires the optional Ethernet gateway module. Once installed, users access real-time chamber status, historical trends, and alarm history via secure web interface or mobile application.
How is humidity accuracy maintained over extended operation?
The chamber employs a factory-trimmed capacitive RH sensor with automatic self-diagnostic routines. Drift compensation algorithms and periodic auto-zero cycles ensure long-term accuracy without field recalibration.
