Labonce Labonce-15000GS Walk-in Pharmaceutical Stability Chamber

Overview

The Labonce Labonce-15000GS Walk-in Pharmaceutical Stability Chamber is an engineered environmental test system designed specifically for long-term, real-time stability studies of pharmaceutical products in accordance with ICH Q1A(R3), Q5C, and the Chinese Pharmacopoeia 2020 Edition. It operates on a precision-controlled forced-air convection principle, utilizing a dual-loop PID algorithm to regulate temperature and humidity independently across its 15,000-liter internal volume. The chamber maintains thermodynamic equilibrium through a fully stainless-steel 304 air distribution ductwork and laminar airflow design—ensuring spatial uniformity within ±0.5°C temperature and ±3.0% RH humidity across all validated test points. Its structural architecture supports full compliance with GLP and GMP validation requirements, including mapping protocols per ISO 14644-3 and qualification documentation aligned with Annex 15 of the EU Guidelines to Good Manufacturing Practice.

Key Features

• Stainless-steel 304 interior construction—including floor with anti-slip patterned plating, insulated double-glazed observation window with defrost heating, and integrated LED lighting
• Dual-compressor refrigeration system with redundant backup capacity and variable-frequency drive (VFD) option for ≥50% energy reduction under partial-load conditions
• 7-inch industrial-grade color touchscreen controller supporting ≥3-tier user access control (administrator, supervisor, operator), password-protected parameter modification, and time-stamped session logging
• Capacitive humidity sensor (imported, calibrated traceably to NIST standards) offering long-term drift <0.5% RH/year and zero routine calibration requirement
• Comprehensive alarm architecture: local audible/visual alerts plus remote SMS notification for critical events including temperature/humidity excursions, low water level, power failure, and door open duration exceedance
• Integrated safety systems: keyed mechanical door lock with anti-reverse-latch function, internal emergency stop button, over-temperature/over-humidity cut-off, compressor high-pressure protection, and phase-failure detection

Sample Compatibility & Compliance

The Labonce-15000GS accommodates diverse pharmaceutical dosage forms—including tablets, capsules, injectables, lyophilized powders, and biologics—within configurable shelving layouts optimized for airflow penetration and thermal mass loading. Its validation-ready design conforms to regulatory expectations for stability-indicating environments: temperature mapping per USP , humidity uniformity assessment per ASTM E2877-22, and data integrity alignment with FDA 21 CFR Part 11 (when equipped with optional network server module). The system supports installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) documentation packages, and is pre-configured for IQ/OQ execution using certified reference probes traceable to national metrology institutes.

Software & Data Management

The embedded controller firmware implements deterministic real-time logging at user-defined intervals (1–60 minutes), storing ≥12 months of continuous temperature/humidity data internally. All records include operator ID, timestamp, setpoint, actual reading, and deviation status. Audit trail functionality captures every configuration change, manual override, or alarm acknowledgment—with immutable export capability via USB flash drive in CSV or PDF/A-1b format. Optional network server integration enables centralized monitoring of multiple chambers, automated report generation (e.g., monthly stability summary, excursion trending), role-based web dashboard access, and electronic signature support compliant with 21 CFR Part 11 Subpart B.

Applications

• ICH-aligned long-term (25°C/60% RH) and accelerated (40°C/75% RH) stability testing per Q1A(R3)
• Intermediate condition studies (30°C/65% RH) and low-humidity protocols (25°C/40% RH, 40°C/25% RH)
• Excursion tolerance evaluation for cold chain deviations during transport or storage
• Stability protocol execution for ANDA submissions, MAAs, and post-approval lifecycle management
• Reference standard storage under controlled ambient conditions meeting USP and Ph. Eur. 2.1.33 requirements
• Environmental stress screening of packaging components and primary containers

FAQ

Does the Labonce-15000GS support IQ/OQ/PQ documentation out of the box?
Yes—the system ships with a complete qualification toolkit including URS template, FAT/SAT checklists, sensor calibration certificates, and blank PQ protocol worksheets aligned with ISO/IEC 17025 and WHO TRS 992 Annex 9.
Can the chamber be validated for 2–8°C refrigerated storage?
Yes—custom configurations are available with extended low-temperature capability (2–8°C, ±1.0°C uniformity), incorporating enhanced insulation, cryogenic-grade refrigerant circuitry, and dedicated cold-room airflow optimization.
Is remote monitoring and alarm escalation supported without the optional server package?
Basic SMS-based remote alerts are built-in; however, web-based dashboards, historical trend analysis, and multi-chamber fleet management require the optional network server module.
What is the expected service life of the capacitive humidity sensor?
The imported sensor exhibits typical field longevity exceeding 8 years under continuous operation, with no scheduled recalibration required per manufacturer specifications and ICH Q5C guidance.
How does the system handle power interruption recovery?
Upon power restoration, the controller resumes the last active program automatically, retaining all logged data and alarm history—no manual reinitialization is necessary.
