Labonce Labonce-250FS Drug Stability Testing Chamber

Overview

The Labonce Labonce-250FS Drug Stability Testing Chamber is an engineered environmental simulation system designed specifically for long-term and accelerated stability studies in compliance with international pharmaceutical regulatory frameworks. It operates on the principle of controlled thermohygrometric conditioning—precisely maintaining defined temperature and relative humidity profiles across extended durations (up to 72 months) to assess chemical degradation kinetics, physical changes, and microbiological stability of drug substances and products. The chamber meets core requirements of ICH Q1A(R2), Q5C, and the Chinese Pharmacopoeia (ChP) 2020 Edition for real-time, intermediate, and accelerated testing conditions—including 25 °C/60 %RH (long-term), 30 °C/65 %RH (intermediate), and 40 °C/75 %RH (accelerated). Its robust architecture integrates dual independent control loops for temperature and humidity, ensuring traceable, reproducible, and GxP-aligned environmental exposure.

Key Features

• Triple-layer air distribution system with bottom-mounted 360° airflow ensures ±0.5 °C temperature uniformity and <±2 %RH humidity uniformity across the full 250 L working volume—validated per ISO 14644-3 and ASTM E2889-13 protocols.
• Hermetically sealed, imported compressor delivers stable cooling performance from 0 °C to 70 °C with noise level <55 dB(A) at 1 m distance—enabling uninterrupted operation in shared laboratory environments.
• Capacitive humidity sensor (imported, factory-traceable calibration) provides high-resolution RH measurement (0.1 %RH resolution) with drift <0.5 %RH/year—eliminating routine recalibration needs.
• 7-inch industrial-grade color touchscreen controller supports up to 20 programmable cycles, each with 32 segments; includes real-time graphing, setpoint ramping, and hold functions compliant with ICH Q1E stepwise protocols.
• Three-tier user permission model (Operator / Supervisor / Administrator) enforces role-based access control; all login attempts, parameter modifications, and alarm acknowledgments are permanently logged with timestamps and user IDs.
• Dual-door configuration minimizes thermal/hygrometric disturbance during sample inspection: outer door maintains insulation integrity while inner tempered glass allows visual monitoring without compromising chamber stability.

Sample Compatibility & Compliance

The Labonce-250FS accommodates a wide range of pharmaceutical sample formats—including blister packs, vials, ampoules, bottles, sachets, and stability-indicating reference standards—within its mirror-polished 304 stainless steel interior. This non-porous, corrosion-resistant surface prevents leachables, resists cleaning agents (e.g., 70 % IPA, hydrogen peroxide vapor), and complies with USP for extractables profiling. The chamber’s construction adheres to ISO 14644-1 Class 8 cleanroom-compatible practices, and its validation documentation package supports IQ/OQ/PQ execution per ASTM E2500 and Annex 15. All firmware and software components meet FDA 21 CFR Part 11 requirements for electronic records and signatures—including audit trail immutability, electronic signature enforcement, and data integrity safeguards (ALCOA+ principles).

Software & Data Management

The integrated network-enabled monitoring software (Labonce StabilitySuite™) provides centralized remote supervision of multiple chambers via secure HTTPS/TLS 1.2 connection. It supports automated generation of PDF reports aligned with ICH M4(R4) eCTD structure, including trend analysis, deviation alerts, and raw data export in CSV and PDF/A-1a formats. Internal non-volatile memory retains ≥12 months of minute-interval environmental data (temperature, humidity, alarms, events), while the built-in thermal printer outputs time-stamped hard copies for immediate review. USB export functionality delivers audit trail logs in read-only .pdf or .csv formats—ensuring compliance with EU Annex 11 and WHO TRS 996 data retention mandates.

Applications

• ICH-compliant long-term stability testing (25 °C/60 %RH, 30 °C/65 %RH) for registration batches and commercial release.
• Accelerated stability assessment (40 °C/75 %RH) to predict shelf life and identify degradation pathways.
• Photostability pre-screening when used in conjunction with optional ICH Q1B-compliant light cabinets.
• Forced degradation studies under stressed conditions (e.g., 60 °C, 90 %RH) to validate analytical methods.
• Storage condition qualification for cold chain intermediates (e.g., 5 °C/≤20 %RH) and excipient compatibility testing.
• Environmental stress testing of packaging systems per ISO 11607-1 for seal integrity and moisture barrier performance.

FAQ

Does the Labonce-250FS support 21 CFR Part 11 compliance out-of-the-box?
Yes—the system includes validated electronic signature workflows, immutable audit trails, and role-based access controls fully aligned with FDA 21 CFR Part 11 Subpart B requirements.
Can humidity be maintained at ≤10 %RH for desiccant-based stability studies?
No—the specified operational humidity range is 10–80 %RH; sub-10 %RH conditions require dedicated dry-air purge systems not integrated into this model.
Is third-party IQ/OQ protocol documentation provided with purchase?
Yes—a comprehensive vendor-supplied IQ/OQ template package—including test scripts, acceptance criteria, and blank execution records—is delivered with the instrument and supports customer-specific PQ adaptation.
What is the maximum allowable ambient temperature for continuous operation?
The unit is rated for uninterrupted use at ambient temperatures between +5 °C and +35 °C; operation outside this range may compromise humidity control accuracy and compressor longevity.
Are calibration certificates for the temperature and humidity sensors included?
Factory calibration certificates (NIST-traceable for temperature, ISO/IEC 17025-accredited for humidity sensor) are supplied with each unit, along with uncertainty budgets and calibration intervals.
