Labonce Labonce-50CT Drug Stability Testing Chamber

Overview

The Labonce Labonce-50CT Drug Stability Testing Chamber is an ICH-compliant environmental simulation system engineered for long-term and accelerated stability studies of pharmaceutical products, packaging materials, and excipients under controlled temperature conditions. Designed in accordance with the principles outlined in ICH Q1A(R2), Q5C, and Q5D, this chamber maintains precise thermal environments essential for evaluating product degradation kinetics, shelf-life prediction, and regulatory submission support. Its core operational principle relies on forced-air convection via a dynamically balanced air circulation system, ensuring minimal thermal stratification and high spatial reproducibility across the 50 L working volume. Unlike general-purpose incubators, the Labonce-50CT integrates pharmaceutical-grade control architecture—including configurable test profiles, real-time deviation monitoring, and electronic audit trail—making it suitable for GLP and GMP-aligned laboratories conducting stability testing per USP , FDA 21 CFR Part 11, and ISO/IEC 17025 requirements.

Key Features

• High-fidelity temperature control: Achieves ±0.5 °C fluctuation and <±1.0 °C deviation over the full 0–85 °C operating range, validated per ASTM E2297 and ISO 16770 protocols.
• Optimized airflow architecture: Patented horizontal laminar air distribution system minimizes thermal gradients, delivering ≤2.0 °C uniformity throughout the chamber cavity—even during door-opening events.
• Pharmaceutical-grade controller: 7-inch color touchscreen interface supporting up to 100 programmable cycles, multi-step ramp/soak profiles, and password-protected user roles (Operator, Supervisor, Administrator) with full action logging.
• Dual-door thermal isolation: Outer insulated solid door prevents ambient light intrusion and heat loss; inner tempered glass door enables non-intrusive visual inspection without compromising chamber stability.
• Energy-efficient refrigeration: Equipped with an imported inverter-driven compressor that modulates cooling capacity in real time—reducing power consumption by >50% compared to fixed-speed alternatives while extending component service life.
• Robust mechanical construction: Exterior finished with corrosion-resistant epoxy powder coating; interior chamber fabricated from electropolished 304 stainless steel with seamless welds and coved corners for ease of cleaning and microbial control.
• Comprehensive safety redundancy: Independent mechanical over-temperature cut-off circuit operates separately from the main controller, providing fail-safe protection for both samples and hardware.

Sample Compatibility & Compliance

The Labonce-50CT accommodates standard pharmaceutical stability storage configurations—including open trays, nested vials, blister packs, and primary packaging units—within its 400 × 310 × 350 mm stainless-steel chamber. Its design conforms to national and international standards governing environmental test equipment performance, including GB/T 10586–2006 (Chinese national standard for damp heat chambers), ISO 16770:2015 (performance verification of environmental test chambers), and ASTM E2297–21 (standard guide for qualification of stability chambers). All firmware and data handling functions are structured to meet FDA 21 CFR Part 11 requirements for electronic records and signatures, including secure user authentication, immutable audit trails, and exportable raw data logs in CSV format.

Software & Data Management

Data integrity is ensured through embedded non-volatile memory capable of storing ≥12 months of continuous temperature history at 1-minute intervals. The controller supports USB 2.0 mass storage export—enabling traceable transfer of calibration logs, alarm histories, profile executions, and real-time trend charts without network dependency. Optional integration with Labonce’s centralized LabManager™ software suite permits remote monitoring, multi-chamber synchronization, automated report generation (PDF/Excel), and alignment with LIMS or ELN platforms via RESTful API. All electronic records include timestamps, operator IDs, event types, and digital signatures compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

• ICH Q1A(R2) long-term and accelerated stability studies (e.g., 25 °C/60% RH, 40 °C/75% RH)
• Forced degradation testing of APIs and drug products under elevated temperature stress
• Primary and secondary packaging compatibility evaluation (e.g., thermal resistance of PVC/PVDC blisters, HDPE bottles)
• Excipient compatibility screening during formulation development
• Accelerated aging of medical device components per ISO 11607–1
• Reference standard storage under defined ambient conditions
• Raw material qualification per USP and Ph. Eur. 2.2.47

FAQ

Is the Labonce-50CT qualified for GMP-regulated stability programs?
Yes—the chamber meets critical GMP expectations for equipment qualification (IQ/OQ/PQ), includes built-in calibration verification routines, and supports 21 CFR Part 11 compliance when configured with enabled audit trail and user access controls.
Can temperature profiles be exported for regulatory submission?
Absolutely. All test profiles, runtime logs, alarm events, and calibration certificates can be exported in timestamped, digitally signed CSV or PDF formats compatible with regulatory dossier assembly.
What validation documentation is provided with the unit?
Each Labonce-50CT ships with a Factory Acceptance Test (FAT) report, as-installed calibration certificate (traceable to NIM, China), user manual, and IQ/OQ protocol templates aligned with Annex 15 and ASTM E2500.
Does the system support humidity control?
No—the Labonce-50CT is a dedicated temperature-only stability chamber. For combined temp/humidity applications, consider the Labonce-50CH series, which complies with ICH Q1B photostability and Q5C freeze-thaw requirements.
How often does the system require recalibration?
Annual recalibration is recommended per ISO/IEC 17025 guidelines; however, internal sensor drift compensation and self-diagnostics enable extended calibration intervals when supported by documented risk assessment and trending analysis.
