Labonce labonce-430CGS-FC Combined Temperature-Humidity-Light Stability Chamber for Pharmaceutical Testing

Overview

The Labonce labonce-430CGS-FC is a tri-compartment pharmaceutical stability chamber engineered specifically for ICH-compliant long-term, accelerated, and intermediate condition testing of drug substances and products. Its three independent chambers—A (temperature + visible light + near-UV), B (temperature + humidity), and C (temperature + humidity)—enable simultaneous execution of multiple ICH Q1 protocols under rigorously controlled and mutually isolated environmental conditions. The system operates on the principle of forced-air convection with dual PID-controlled heating/cooling circuits per chamber, coupled with precision capacitive humidity sensing and calibrated photometric irradiance monitoring. Designed for regulatory-grade data integrity, it supports full traceability requirements under FDA 21 CFR Part 11, EU Annex 11, and Chinese GMP Annexes for stability testing laboratories.

Key Features

• Tri-compartment architecture: Physically separated A (light-exposed), B (temp/humidity), and C (temp/humidity) chambers eliminate cross-contamination of environmental parameters and enable concurrent multi-condition studies.
• Energy-efficient refrigeration: Imported hermetic inverter compressor reduces power and water consumption by over 50% versus fixed-speed systems, maintaining stable thermal performance across ambient temperatures from +5°C to +35°C.
• High-fidelity illumination subsystem: A-box integrates factory-calibrated visible-light (100–6000 lux) and near-UV (0.84–1.0 W/m²) sources with real-time irradiance feedback, meeting ICH Q1B photo-stability test energy thresholds (≥1.2 × 10⁶ lux·hr visible; ≥200 W·h/m² near-UV).
• Triple-tier user access control: Role-based authentication (Administrator, Supervisor, Operator) enforces procedural separation of duties; password-protected login with session timeout and failed-attempt lockout.
• Audit trail functionality: All critical events—including parameter changes, alarm triggers, door openings, and user logins—are timestamped, user-identified, and stored in an immutable binary log file format; exportable via USB to PDF or CSV with cryptographic integrity verification.
• Robust chamber construction: Exterior cold-rolled steel with epoxy-polyester powder coating; interior 304 stainless-steel mirror-finish liner resistant to corrosion, leaching, and microbial retention.
• Thermal and hygric performance: Achieves ±0.5°C temperature fluctuation and ±2% RH fluctuation (no light); uniformity maintained at ±1.0°C and ±3% RH respectively under static load conditions per ISO 16770 and ASTM E2805.

Sample Compatibility & Compliance

The labonce-430CGS-FC accommodates standard pharmaceutical packaging formats—including blister packs, vials, bottles, sachets, and primary/secondary containers—within its configurable shelf layout (1 shelf in A, 2 in B, 4 in C). All internal surfaces are non-outgassing and compatible with sterile handling practices. The system conforms to ICH Q1A(R2), Q1B, Q5C, and the Chinese Pharmacopoeia 2020 Edition Chapter 9001 “Stability Testing of Drug Substances and Products.” It supports qualification documentation (IQ/OQ/PQ) and is pre-engineered for integration into GMP- and CGMP-regulated quality systems, including alignment with WHO TRS 992 Annex 6 and PIC/S PI 007-6 for stability storage facilities.

Software & Data Management

Equipped with a 7-inch full-color programmable touchscreen controller featuring real-time graphical display of setpoints, actual values, and inverter output percentage, the system logs all operational data at user-defined intervals (1–60 min resolution). Embedded memory retains ≥12 months of continuous environmental data. Optional RS485/Modbus RTU and Ethernet interfaces support centralized monitoring via LIMS or SCADA platforms. The integrated thermal printer provides immediate hardcopy of alarm summaries and daily condition reports. Electronic records comply with ALCOA+ principles: Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, and Available—fully supporting 21 CFR Part 11 electronic signature and audit trail requirements.

Applications

• ICH Q1A(R2) long-term (25°C/60% RH), accelerated (40°C/75% RH), and intermediate (30°C/65% RH) stability studies.
• ICH Q1B photostability testing (Option 1 and Option 2 protocols) using calibrated visible and near-UV irradiation.
• Forced degradation studies under controlled stress conditions (e.g., elevated temperature/humidity combinations).
• Reference standard storage under defined climatic conditions per USP and Ph. Eur. 5.19.
• Stability protocol validation and chamber mapping per ISO 16770 Annex B and ASTM E2805 Section 8.
• QC release testing support for humidity-sensitive formulations (e.g., lyophilized powders, hygroscopic APIs).

FAQ

Does the labonce-430CGS-FC meet ICH Q1B photostability requirements?
Yes—the A compartment delivers traceable visible light (4500 ± 500 lux) and near-UV irradiance (≥200 W·h/m²) with built-in sensors and automatic data logging to satisfy ICH Q1B Option 1 and Option 2 exposure criteria.
How is data integrity ensured during power interruption?
The controller retains all configuration and logged data in non-volatile flash memory; upon recovery, it resumes operation without data loss and timestamps the outage event in the audit trail.
Can the system be qualified for GMP use?
Yes—it includes IQ/OQ documentation templates, mapping-ready sensor ports (up to 12 PT100 inputs), and supports third-party PQ execution per ISO 16770 and ASTM E2805.
What humidity sensor technology is used?
Capacitive polymer humidity sensors (imported, factory-calibrated) with ±1.5% RH accuracy, <±0.1% RH/year drift, and no routine recalibration required.
Is remote alarm notification supported?
Yes—via GSM module (optional), the system sends SMS alerts for temperature/humidity excursions, power failure, door open duration >60 sec, and critical fault conditions.
