Labonce Labonce-20000GS Walk-in Pharmaceutical Stability Chamber

Overview

The Labonce Labonce-20000GS Walk-in Pharmaceutical Stability Chamber is a GMP-aligned, validation-ready environmental test system engineered for long-term stability studies of pharmaceutical products in accordance with ICH Q1 series guidelines (Q1A–Q1E), USP <1150>, and the Chinese Pharmacopoeia 2020 Edition. It operates on a precision-controlled forced-air convection principle, utilizing a dual-loop PID algorithm to independently regulate temperature and humidity across its 20,000-liter internal volume. The chamber maintains thermodynamic equilibrium through a fully insulated stainless-steel 304 enclosure, optimized air distribution via a custom-designed laminar wind tunnel, and high-fidelity feedback from calibrated capacitive humidity sensors and Pt100 temperature probes. Designed for 24/7 operation under GLP/GMP conditions, it supports ICH-defined storage conditions—including 25°C/60% RH (long-term), 30°C/65% RH (accelerated), and low-humidity variants such as 40°C/25% RH—while meeting stringent spatial uniformity requirements per JJF 1101-2019 and GB/T 10586-2006.

Key Features

• Stainless-steel 304 interior construction with anti-slip textured floor plating and double-glazed, heated observation windows to prevent condensation
• Dual-stage refrigeration system featuring imported hermetic compressors with redundant backup capacity and variable-frequency drive (VFD) option for ≥50% energy reduction
• 7-inch industrial-grade color touchscreen controller with real-time trend visualization, multi-segment programmability, and configurable alarm thresholds
• Triple-tier user permission architecture (Operator / Supervisor / Administrator) enforced via username/password authentication and session timeout
• FDA 21 CFR Part 11–ready audit trail functionality: tamper-evident, time-stamped records of all parameter changes, manual interventions, alarms, and system events
• Capacitive humidity sensing technology with <1% RH long-term drift, factory-calibrated traceability to NIST standards, and zero-maintenance operational life
• Integrated dual-channel thermal mapping capability with ≥2 pre-validated monitoring points (location-determined by IQ/OQ thermal profiling)
• Multi-layer safety system: mechanical door lock with emergency egress button, over-temperature/over-humidity cutoffs, low-water-level detection, and remote SMS alerts for critical deviations

Sample Compatibility & Compliance

The Labonce-20000GS accommodates full-scale stability batches—including primary packaging (blister packs, vials, bottles), secondary cartons, and palletized configurations—without compromising airflow integrity or sensor accessibility. Its uniformity profile (<±0.5°C temperature, <±3.0% RH) satisfies ICH Q5C recommendations for chamber qualification and supports bracketing/matrixing study designs. All hardware and firmware comply with ISO 13485:2016 quality management systems for medical device manufacturers and align with Annex 15 (EU GMP) requirements for qualification documentation (DQ/IQ/OQ/PQ). Optional validation support packages include IQ/OQ protocol templates, calibration certificates (traceable to CNAS-accredited labs), and temperature/humidity mapping reports per ASTM E2297-21.

Software & Data Management

Data integrity is ensured through dual-path recording: embedded non-volatile memory retains ≥12 months of second-by-second environmental logs, while an optional networked server module enables centralized monitoring of multiple chambers across facilities. Electronic records are stored in encrypted CSV or PDF/A-1 format, exportable via USB port in write-once/read-many (WORM) mode to meet ALCOA+ principles. The controller supports configurable electronic signatures, role-based report generation (e.g., daily summary, deviation log, calibration history), and seamless integration with LIMS or MES platforms via Modbus TCP or OPC UA protocols. When configured with Part 11 compliance firmware, the system enforces electronic signature workflows, automatic record retention policies, and immutable audit trail archiving.

Applications

• IQ/OQ/PQ execution for pharmaceutical stability storage qualification per WHO TRS 992 Annex 9 and FDA Guidance for Industry (2022)
• ICH-compliant long-term (25°C/60% RH), intermediate (30°C/65% RH), and accelerated (40°C/75% RH) stability testing of APIs and finished dosage forms
• Photostability assessment when integrated with optional UV/visible light modules (IEC 60068-2-5 compliant)
• Reference standard storage under controlled conditions meeting USP <1079> and EP 2.1.7 requirements
• Biological product storage at 2–8°C (optional low-temperature configuration) with enhanced humidity control for lyophilized formulations
• Environmental stress screening of packaging materials per ISTA 3A and ASTM D4332

FAQ

Does the Labonce-20000GS support FDA 21 CFR Part 11 compliance?
Yes—when equipped with the optional Part 11 firmware package, it provides electronic signature enforcement, audit trail immutability, and role-based access controls required for regulated submissions.
Can the chamber be validated for GMP use?
Absolutely. It ships with DQ documentation and supports full IQ/OQ/PQ execution using vendor-provided protocols aligned with Annex 15 and ASTM E2500-13.
Is remote monitoring available?
Yes—via optional Ethernet-connected server module enabling real-time dashboard access, automated email/SMS alerts, and historical data export through secure HTTPS interface.
What is the minimum temperature achievable with optional low-temperature configuration?
The chamber can be configured for cold storage down to 2°C with ±1.0°C uniformity and ±2.0°C deviation, suitable for refrigerated stability studies.
How is humidity accuracy maintained over time?
Through factory-traceable calibration of capacitive sensors, periodic verification using chilled-mirror hygrometers, and automatic drift compensation algorithms embedded in the control firmware.
