Labonce Labonce-620CGS-FC Dual-Chamber Drug Stability Testing Chamber

Overview

The Labonce Labonce-620CGS-FC Dual-Chamber Drug Stability Testing Chamber is an ICH Q1-compliant, GMP-aligned environmental simulation system engineered for long-term and accelerated stability studies of pharmaceutical products in accordance with ICH Q1A(R3), Q1B, Q5C, and the Chinese Pharmacopoeia (2020 Edition). Unlike single- or triple-chamber designs, this dual-chamber configuration separates temperature/humidity conditioning (Chamber B) from photostability testing (Chamber A), enabling simultaneous yet independent execution of ICH Q1B photostability protocols and Q1A thermal-hygrometric stress conditions. Chamber A integrates calibrated visible light (100–6000 lux) and near-ultraviolet irradiation (0.84–1.0 W/m²) with real-time sensor feedback, while Chamber B maintains precise thermo-hygrometric control across 15–65°C and 20–95% RH. The system employs Couette-flow-based air distribution, high-density polyurethane foam insulation (≥120 mm thickness), and a dual-door structure—featuring an inner tempered glass door for non-invasive observation and an outer solid insulated door—to minimize thermal/hygrometric perturbation during access.

Key Features

• Independent dual-chamber architecture: Chamber A (temperature + humidity + visible light + near-UV) and Chamber B (temperature + humidity only), each with fully programmable setpoints and real-time monitoring.
• ICH Q1B-compliant photostability module: Integrated visible light (4500 ± 500 lux target) and near-UV (≥200 W·hr/m² cumulative dose) irradiation, with automatic logging of irradiance values and exposure duration.
• High-efficiency refrigeration: Imported hermetic variable-frequency compressor delivering ≥50% energy and water savings versus fixed-speed systems; optimized for continuous operation under high-humidity, high-temperature load profiles.
• Triple-tier user authentication: Role-based access control (Administrator, Supervisor, Operator) with password-protected login, session timeout, and mandatory credential revalidation for critical actions.
• Audit trail compliance: Full electronic record of all parameter changes, alarm events, door openings, and calibration activities—exportable via USB in immutable .csv format per FDA 21 CFR Part 11 requirements.
• Precision environmental control: Temperature stability ±0.5°C (fluctuation), ±1.0°C (uniformity, dark condition); humidity stability ±2% RH (fluctuation), ±3% RH (uniformity, dark condition).
• Robust mechanical design: Exterior powder-coated steel housing; interior 304 stainless steel mirror-finish chamber walls; double-glazed inner door with low-emissivity coating; external door with magnetic seal and thermal break.

Sample Compatibility & Compliance

The Labonce-620CGS-FC accommodates standard pharmaceutical packaging formats—including blister packs, vials, ampoules, sachets, and secondary cartons—on adjustable 304 stainless steel shelves (3 standard shelves per chamber, max 9 total). Chamber dimensions (600 × 500 × 1000 mm W×D×H) support ISO 17025-aligned placement of reference sensors per ICH Q5C Annex 1. All environmental profiles comply with regulatory validation requirements for stability-indicating methods, including qualification against ASTM E2798 (Standard Practice for Validation of Environmental Chambers) and alignment with WHO TRS 1010 Annex 9. The system meets GLP/GMP documentation standards for traceability, data integrity, and change control, and supports IQ/OQ/PQ protocol execution with full metadata capture.

Software & Data Management

Equipped with a 7-inch full-color programmable touchscreen controller, the system provides real-time visualization of chamber setpoints, actual values, compressor output ratio, and sensor health status. Embedded firmware supports up to 100 multi-step programs with ramp/soak logic, event-triggered alarms, and automatic recovery after power interruption. Data is stored internally for ≥12 months (timestamped, CRC-verified) and exportable via USB to external media in read-only format. Optional RS485/Modbus RTU or Ethernet (TCP/IP) interfaces enable integration into centralized LIMS or MES platforms. Electronic records include operator ID, timestamp, action type, pre-change/post-change values, and reason-for-change field—fully compliant with FDA 21 CFR Part 11 Subpart C (electronic signatures) and EU Annex 11.

Applications

• ICH Q1A(R3) long-term (25°C/60% RH) and accelerated (40°C/75% RH) stability studies for APIs and finished dosage forms.
• ICH Q1B photostability testing per Option 1 (optionally Option 2) using both visible and near-UV spectra.
• Forced degradation studies under controlled thermal, humid, and photochemical stress.
• Package compatibility testing (e.g., moisture barrier performance under cyclic RH conditions).
• Reference standard storage under defined climatic conditions per USP and Ph. Eur. 5.20.1.
• Validation of stability-indicating analytical methods requiring environmental correlation.

FAQ

Does the Labonce-620CGS-FC meet ICH Q1B photostability requirements for both visible and near-UV irradiation?
Yes. Chamber A is equipped with calibrated broadband visible (320–800 nm) and near-UV (320–400 nm) light sources, with integrated sensors measuring irradiance in real time. Cumulative exposure is logged automatically and meets the minimum 1.2 × 10⁶ lux·hr (visible) and 200 W·hr/m² (near-UV) thresholds specified in ICH Q1B.
Is audit trail functionality compliant with FDA 21 CFR Part 11?
Yes. The system implements role-based electronic signatures, immutable data export, operator attribution, and time-stamped records of all critical events—including parameter modifications, alarm acknowledgments, and calibration interventions—satisfying Subparts A and C of 21 CFR Part 11.
What is the maximum shelf load capacity and material compatibility?
Each chamber supports up to 9 stainless steel shelves (304 grade, 500 × 600 mm), rated for ≤15 kg per shelf. All wetted surfaces are electropolished 304 stainless steel, ensuring chemical inertness and compatibility with ethanol, IPA, hydrogen peroxide vapor, and other common cleanroom disinfectants.
Can the system be validated per GMP requirements?
Yes. The Labonce-620CGS-FC includes factory-provided IQ/OQ documentation templates, sensor calibration certificates (NIST-traceable), and a comprehensive user manual aligned with ISO/IEC 17025 and EU GMP Annex 15. On-site PQ support is available through certified third-party service partners.
How is temperature and humidity uniformity verified across the working volume?
Uniformity is validated per ASTM E2798 using 9-point mapping (3×3 grid at center plane) with NIST-traceable Class A probes. Typical results demonstrate ≤±0.8°C temperature deviation and ≤±3.5% RH deviation across the full 300 L volume under steady-state conditions.
