Labonce Labonce-520LGS Dual-Chamber Pharmaceutical Stability Testing Chamber (Pharmaceutical Packaging Dedicated)

Overview

The Labonce Labonce-520LGS is a dual-chamber, pharmaceutical packaging–dedicated stability testing chamber engineered to meet stringent regulatory requirements for long-term, accelerated, and intermediate condition studies under ICH Q1A(R3), Q1B, Q5C, and the Chinese Pharmacopoeia (2020 Edition). Unlike conventional single-zone chambers, its two physically isolated 250 L chambers operate independently—enabling simultaneous execution of distinct test protocols (e.g., 25 °C/60 %RH vs. 40 °C/75 %RH) without cross-contamination or thermal/hygrometric interference. Each chamber employs a closed-loop humidity control system with desiccant-assisted dehumidification, validated to sustain ultra-low humidity conditions down to 10 %RH at 60 °C—critical for evaluating moisture-sensitive packaging systems such as blister foils, sachets, and desiccant-containing vials. The unit’s thermodynamic architecture integrates high-efficiency refrigeration, precision PID-controlled steam humidification, and low-thermal-mass stainless-steel interiors to ensure high reproducibility across repeated validation cycles.

Key Features

• Dual independent 250 L chambers with fully segregated air paths, temperature/humidity control loops, and programmable setpoints—eliminating inter-chamber drift during concurrent multi-condition testing.
• Ultra-low humidity capability: Validated operation at 60 °C/10 %RH and 25 °C/20 %RH (ambient ≤25 °C), supporting ICH Q1B photostability pre-screening and packaging barrier integrity assessment.
• GMP-compliant control system featuring a 7-inch color touchscreen HMI with three-tier user permissions (Operator, Supervisor, Administrator), full electronic audit trail (21 CFR Part 11–ready metadata logging), and password-protected parameter locking.
• Structural integrity: Mirror-finish AISI 304 stainless-steel interior (electropolished welds, zero crevices), powder-coated carbon steel exterior, and ≥120 mm high-density polyurethane insulation—ensuring thermal stability, corrosion resistance, and ISO 14644–1 Class 8 cleanroom compatibility.
• Redundant safety architecture: Dual independent over-temperature cutoffs (mechanical + electronic), compressor overheat/overpressure protection, auto-shutoff on water reservoir depletion, and dry-burn prevention in humidifier elements.
• Remote monitoring readiness: Integrated GSM module supports SMS alerts for out-of-specification excursions (±1.5 °C / ±5 %RH deviation), power failure, door ajar, and system fault codes—configurable per chamber.

Sample Compatibility & Compliance

The Labonce-520LGS accommodates primary and secondary pharmaceutical packaging configurations—including blister cards, HDPE bottles, aluminum tubes, glass vials with rubber stoppers, and laminated pouches—without compromising chamber uniformity. Its double-door design (outer insulated steel door + inner tempered glass door) minimizes thermal load during routine visual inspection, maintaining internal stability within specification limits for ≤30 s door openings. All materials contacting the test environment comply with USP and ISO 10993–1 biocompatibility guidelines. The chamber undergoes factory-installed IQ/OQ documentation per ASTM E2500 and ISPE Good Automated Manufacturing Practice (GAMP® 5), with optional PQ support for site-specific qualification against Annex 15 and EU GMP Annex 15 requirements.

Software & Data Management

Embedded firmware supports up to 100 programmable test profiles, each with 20 segments (ramp/soak), real-time trend visualization, and automatic data capture at user-defined intervals (1–60 min). All operational data—including sensor readings, alarm events, user actions, and calibration logs—are timestamped, digitally signed, and stored internally for ≥12 months. Data export via USB 2.0 yields CSV-formatted files compatible with LIMS, ELN, and statistical process control platforms (e.g., JMP, Minitab). Optional thermal micro-printer provides immediate hard-copy records for shift handovers or audit preparation. Full compliance with FDA 21 CFR Part 11 is achieved through role-based electronic signatures, immutable audit trails, and secure data encryption (AES-256).

Applications

• ICH Q1A(R3) long-term (25 °C/60 %RH) and accelerated (40 °C/75 %RH) stability studies for drug product registration dossiers.
• Primary packaging compatibility testing per ICH Q5C, including moisture permeation rate evaluation of cold-form blisters and child-resistant closures.
• Accelerated aging of combination products (e.g., prefilled syringes with elastomeric components) under controlled RH gradients.
• GMP-aligned requalification of storage conditions following facility HVAC modifications or packaging line transfers.
• Reference standard storage validation per USP and Ph. Eur. 2.2.47, ensuring certified reference material integrity over extended holding periods.

FAQ

Does the Labonce-520LGS support 21 CFR Part 11 compliance?
Yes—the system includes electronic signature capability, audit trail generation with immutable timestamps, and role-based access controls aligned with Part 11 Subpart B requirements.
Can both chambers run different humidity setpoints simultaneously?
Yes—each chamber has independent humidity generators, sensors, and control algorithms, enabling concurrent operation at, for example, 40 °C/75 %RH and 25 °C/20 %RH.
What validation documentation is provided with the unit?
Factory IQ/OQ protocols compliant with ASTM E2500 and ISPE GAMP® 5 are included; PQ templates and on-site qualification support are available upon request.
Is the chamber suitable for photostability testing per ICH Q1B?
The base 520LGS model does not include light sources; however, the 520LCGS variant adds calibrated visible (100–8000 lux) and near-UV (0.84–5 W/m²) irradiation modules with integrated spectral monitoring.
How is temperature and humidity uniformity verified across the chamber volume?
Uniformity mapping per ISO 16730 and ASTM F2655 is performed using 9-point sensor arrays during FAT; reports document worst-case deviations across all operational setpoints.
