Labonce Labonce-1500GS-FC Dual-Door Stability Testing Chamber

Overview

The Labonce Labonce-1500GS-FC Dual-Door Stability Testing Chamber is an engineered environmental simulation system designed specifically for long-term pharmaceutical stability studies under ICH Q1–Q5 guidelines and Chinese Pharmacopoeia (2020 Edition) requirements. It operates on a precisely regulated dual-climate control principle—simultaneously maintaining stable temperature and relative humidity across its 1500 L working volume using closed-loop feedback from high-stability capacitive humidity sensors and platinum resistance temperature detectors (PT100). Its inverter-driven refrigeration architecture enables continuous 24/7 operation with minimal thermal inertia, ensuring compliance with GMP and cGMP environments where reproducibility, traceability, and uninterrupted test integrity are non-negotiable.

Key Features

• Inverter-controlled hermetic refrigeration system delivering >50% energy and water savings versus fixed-speed alternatives, with dynamic load adaptation to ambient fluctuations between +5 °C and +35 °C.
• Dual-door configuration: outer solid insulated door minimizes heat/moisture exchange; inner tempered glass door allows visual monitoring without compromising chamber stability—validated to limit internal RH deviation to <1.5 %RH during brief observation intervals.
• Mirror-finish AISI 304 stainless-steel interior eliminates particulate shedding and supports validated cleaning protocols; seamless welded corners prevent microbial harborage.
• 7-inch full-color programmable touchscreen controller with real-time visualization of inverter output percentage, setpoint tracking, and deviation alarms—designed for intuitive SOP-driven operation.
• Three-tier user permission structure (Administrator / Supervisor / Operator) enforced via encrypted username/password authentication; each role restricts access to calibration, parameter modification, or audit log export functions.
• Comprehensive safety redundancy: independent mechanical overtemperature cut-off, compressor thermal overload relay, low-water detection, anti-dry-burn heater protection, and phase-failure monitoring.

Sample Compatibility & Compliance

The Labonce-1500GS-FC accommodates diverse pharmaceutical dosage forms—including tablets, capsules, injectables, lyophilized powders, and primary packaging materials—on four standard adjustable stainless-steel shelves (load capacity: 25 kg/shelf). Its uniformity performance (±1.0 °C temperature deviation, ±3 %RH humidity deviation per ICH Q1A(R2) Annex 2) has been verified per ISO 14644-1 Class 8 cleanroom-compatible airflow mapping. The system meets design and documentation requirements for FDA 21 CFR Part 11 compliance when paired with Labonce’s optional electronic signature module. All firmware and calibration records adhere to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), supporting GLP/GMP audits and regulatory submissions.

Software & Data Management

Data integrity is maintained through synchronized internal logging (≥12 months at 1-minute intervals) and external export capability via USB 2.0 port. Audit trails capture operator ID, timestamp, action type (e.g., setpoint change, door open event, calibration initiation), and pre-/post-value states—all stored in immutable .CSV format with SHA-256 hash verification. Optional Ethernet connectivity enables integration with LIMS or MES platforms using Modbus TCP or OPC UA protocols. Thermal line printer provides immediate hardcopy of current conditions and alarm summaries—configured to activate automatically upon deviation exceedance or cycle completion.

Applications

• I CH Q1A(R2) long-term (25 °C/60 %RH), accelerated (40 °C/75 %RH), and intermediate (30 °C/65 %RH) stability protocols.
• Photostability testing per ICH Q5C when combined with optional UV/visible light modules (not included).
• Accelerated aging studies for medical device packaging per ASTM F1980.
• Reference standard storage under controlled conditions compliant with USP and Ph. Eur. 2.9.40.
• QC release testing support for hygroscopic APIs and moisture-sensitive excipients.

FAQ

Does the Labonce-1500GS-FC comply with 21 CFR Part 11 for electronic records?
Yes—when configured with the optional digital signature license and time-synchronized NTP server, all electronic records meet Part 11 requirements for audit trail completeness, operator authentication, and record retention.
What is the validation support package available for this chamber?
Labonce provides IQ/OQ documentation templates aligned with ASTM E2500 and Annex 15; factory-verified temperature/humidity mapping reports (16-point sensor grid) and sensor calibration certificates (NIST-traceable) are included with shipment.
Can the system be integrated into a central monitoring network?
Yes—via optional RS485/Modbus RTU or Ethernet/IP interfaces, enabling centralized alarm aggregation, remote parameter adjustment, and historical data aggregation in SCADA or cloud-based platforms.
Is the humidity sensor field-replaceable without recalibration?
The capacitive RH sensor is modular and pre-calibrated; replacement requires only firmware recognition—not manual recalibration—reducing downtime and qualification effort.
What maintenance intervals are recommended for GMP operation?
Compressor oil inspection every 24 months; condensate drain line cleaning quarterly; HEPA filter replacement annually; full preventive maintenance (including sensor verification and door gasket integrity check) biannually per Labonce PM-003 protocol.
