Labonce Labonce-520LCGS Dual-Chamber Pharmaceutical Stability Testing Chamber (Independent Dual-Zone, Drug Packaging Dedicated)

Overview

The Labonce Labonce-520LCGS is a dual-chamber, independently controlled pharmaceutical stability testing chamber engineered specifically for drug packaging qualification and ICH-compliant stability studies. It implements precise thermohygrometric regulation across two physically isolated compartments—Chamber A (temperature + humidity + visible light + near-UV irradiation) and Chamber B (temperature + humidity only)—enabling concurrent execution of multiple ICH Q1–Q5 protocols under strictly segregated environmental conditions. The system adheres to the fundamental principles of accelerated and long-term stability testing as defined in ICH Guideline Q5C (Stability Testing of Biotechnological/Biological Products), Q1A(R3) (Stability Testing of New Drug Substances and Products), and the Chinese Pharmacopoeia (2020 Edition), with full support for GMP and cGMP-aligned laboratory workflows. Its ultra-low humidity capability (down to 10% RH at 60°C and 20% RH at 25°C, ambient ≤25°C) meets stringent regulatory requirements for moisture-sensitive packaging materials, including blister foils, desiccant-containing vials, and polymer-based primary containers.

Key Features

• Dual independent chambers: Chamber A integrates temperature, humidity, visible light (100–8,000 lux, ±500 lux @ 4,500 lux setpoint), and near-UV irradiation (0.84–5 W/m²; cumulative dose ≥200 W·hr/m²); Chamber B provides dedicated temperature/humidity control without illumination.
• High-fidelity environmental control: Temperature range 15–65°C (±0.5°C fluctuation, ±1.0°C deviation); humidity range 10–90% RH (±2.0% RH fluctuation, ±3.0% RH deviation).
• GMP-ready controller: Full-color programmable touchscreen interface with three-tier user access (Operator, Supervisor, Administrator), electronic audit trail compliant with FDA 21 CFR Part 11 requirements, and password-protected parameter modification logs.
• Thermal integrity design: Monolithic high-density polyurethane foam insulation (≥120 mm thickness); inner chamber constructed entirely from electropolished AISI 304 stainless steel (mirror finish); outer casing finished with corrosion-resistant powder-coated steel.
• Robust refrigeration & dehumidification: Dual-stage, hermetically sealed imported compressors; optimized air circulation with low-turbulence ducting to ensure uniformity across all shelf levels.
• Integrated safety architecture: Independent over-temperature cutoff, compressor overheat/overpressure protection, water-level monitoring with dry-run prevention, and dual redundant humidity sensors with automatic fault detection.

Sample Compatibility & Compliance

The Labonce-520LCGS accommodates standard pharmaceutical packaging formats—including blister cards, HDPE/PP bottles, glass vials with rubber stoppers, and aluminum-laminated pouches—within its 250 L internal volume per chamber (600 × 500 × 830 mm W×D×H). All internal surfaces are non-shedding, non-reactive, and compatible with routine cleaning validation using ethanol, isopropyl alcohol, or hydrogen peroxide vapor. The system satisfies ISO 14644-1 Class 8 cleanroom-compatible operation and supports GLP/GMP documentation requirements through traceable calibration records, IQ/OQ/PQ protocol templates, and full environmental deviation reporting. It is validated for compliance with ICH Q1B (Photostability Testing), Q5C, and USP “Packaging and Storage Requirements.”

Software & Data Management

Data acquisition is performed continuously at 1-second intervals and stored internally with timestamped metadata (including operator ID, event type, and parameter change history). Raw datasets—including temperature, relative humidity, visible light intensity, and near-UV irradiance—are exportable via USB flash drive in CSV format for integration into LIMS or statistical analysis platforms (e.g., JMP, Minitab). Optional Ethernet connectivity enables remote monitoring and alarm notification via SMTP email or SMS gateway (requires external GSM module). All data storage conforms to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), supporting regulatory inspection readiness.

Applications

• ICH Q1A(R3) long-term (25°C/60% RH) and accelerated (40°C/75% RH) stability studies on finished dosage forms.
• ICH Q5C photostability assessment per Q1B: simultaneous exposure to visible light and near-UV radiation in Chamber A while maintaining identical thermal-hygrometric baselines in Chamber B for comparative analysis.
• Primary packaging compatibility testing: evaluation of moisture barrier performance under ultra-low RH conditions (e.g., 25°C/20% RH, 60°C/10% RH) to assess delamination, seal integrity, and desiccant efficacy.
• Accelerated aging of polymer-based containers per ASTM D3045 and ISO 11341 standards.
• Real-time stability monitoring for clinical trial supply chains requiring documented environmental continuity.

FAQ

Does the Labonce-520LCGS meet ICH Q1B photostability requirements?
Yes—Chamber A is configured with calibrated visible light (4500 ±500 lux) and near-UV (≥200 W·hr/m² cumulative dose) sources, fully aligned with ICH Q1B test conditions.
Can the system operate reliably at 25°C/20% RH?
Yes—the unit achieves and maintains this condition when ambient temperature remains ≤25°C, verified by factory-installed NIST-traceable hygrometers.
Is electronic audit trail functionality compliant with 21 CFR Part 11?
Yes—the system implements role-based authentication, immutable event logging, and digital signature support for critical operations, satisfying Part 11 Subpart B requirements.
What is the maximum allowable ambient operating temperature?
The recommended ambient range is +5°C to +35°C; sustained operation above 35°C may compromise humidity control stability and compressor duty cycle.
Are calibration certificates provided with the instrument?
Yes—each unit ships with a factory calibration report for temperature, humidity, and irradiance sensors, traceable to national metrology institutes.
