Labonce Labonce-400CT Drug Stability Testing Chamber

Overview

The Labonce Labonce-400CT Drug Stability Testing Chamber is an engineered environmental simulation system designed specifically for pharmaceutical stability studies in accordance with ICH Q1–Q5 guidelines and regulatory expectations for long-term, accelerated, and intermediate condition testing. It operates on forced-air convection thermoregulation, utilizing a precision-engineered dual-door architecture and optimized airflow distribution to maintain stable, reproducible thermal conditions across the full 400 L working volume. The chamber supports temperature-controlled storage and stress testing of drug substances and products—including solid oral dosage forms, injectables, and primary packaging materials—under defined climatic conditions required for registration dossiers submitted to FDA, EMA, PMDA, and NMPA. Its design integrates metrological traceability principles, including calibrated sensor redundancy and real-time deviation monitoring, to support GLP and GMP-aligned laboratory operations.

Key Features

• High-fidelity thermal control: Achieves temperature fluctuation <±0.5 °C and uniformity ≤2.0 °C across the entire chamber cavity, validated per ISO 16770 and ASTM E2875 practices.
• Dual-door observation system: Outer solid insulated door minimizes thermal exchange and light intrusion; inner tempered glass door enables non-intrusive sample monitoring without compromising chamber integrity.
• Energy-efficient refrigeration: Equipped with an imported inverter-driven compressor delivering ≥50% reduction in power consumption versus fixed-speed alternatives, while maintaining stable low-temperature performance down to 0 °C.
• Regulatory-grade controller: Full-color touchscreen interface with configurable test profiles, alarm logging, and built-in audit trail functionality compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures.
• Robust mechanical construction: Exterior powder-coated carbon steel housing and seamless 304 stainless steel interior resist corrosion and facilitate cleaning validation per USP and EU Annex 15.
• Independent safety layer: Dedicated over-temperature protection circuit—electrically isolated from the main controller—provides fail-safe shutdown independent of software or user input.

Sample Compatibility & Compliance

The Labonce-400CT accommodates standard stability storage configurations including ICH-compliant trays, aluminum foil-wrapped vials, blister packs, and amber glass containers. Its internal dimensions (600×700×950 mm) allow flexible shelving arrangements supporting up to 10 standardized shelf positions. All materials in contact with the test environment meet USP Class VI biocompatibility criteria. The system complies with GB/T 10586–2006 for damp heat chamber specifications and is pre-qualified for use in protocols aligned with ICH Q1A(R2), Q5C, and WHO TRS 1010 Annex 6. Optional IQ/OQ documentation packages are available upon request to support qualification under GxP frameworks.

Software & Data Management

Data acquisition and reporting are managed via the embedded programmable controller with local non-volatile memory retaining ≥30 days of minute-interval temperature logs. All parameter changes, alarm events, and user logins are time-stamped and recorded within the audit trail, enabling full reconstructability for regulatory inspections. Raw data export is supported via USB flash drive in CSV format—compatible with LIMS integration and statistical process control (SPC) platforms such as JMP or Minitab. No cloud connectivity or remote access features are included, preserving data sovereignty and eliminating cybersecurity vulnerabilities associated with networked instrumentation.

Applications

• ICH-aligned stability studies: Long-term (25 °C/60% RH), accelerated (40 °C/75% RH), and intermediate (30 °C/65% RH) condition testing per Q1A(R2).
• Forced degradation studies: Thermal stress evaluation of active pharmaceutical ingredients (APIs) and finished products at elevated temperatures (up to 85 °C).
• Primary packaging compatibility testing: Assessment of container-closure integrity under thermal cycling and static exposure.
• Material aging analysis: Polymer-based medical device components, adhesives, and elastomeric seals subjected to controlled thermal aging per ISO 11607 and ASTM F1980.
• Reference standard storage: Controlled environment for retention samples and working standards requiring documented thermal history.

FAQ

Is the Labonce-400CT suitable for humidity-controlled stability testing?
No—this model is a temperature-only chamber. For combined temperature/humidity testing, refer to the Labonce-400CH series, which integrates precision humidification and dehumidification modules meeting ICH Q1B photostability and Q5C moisture uptake requirements.
Can the controller be validated for 21 CFR Part 11 compliance?
Yes—the system includes role-based user authentication (Operator, Supervisor, Administrator), electronic signature capability, and immutable audit trail generation. A vendor-supplied Validation Support Package (VSP) with URS, FRS, and test protocols is available for IQ/OQ execution.
What calibration documentation is provided with shipment?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), covering temperature sensors at three spatial points (top/middle/bottom) across the operational range. Certificate includes as-found/as-left data and uncertainty budgets per ISO/IEC 17025.
Is third-party qualification support available?
Yes—Labonce offers optional on-site qualification services performed by certified engineers, including installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) against user-defined acceptance criteria.
Does the chamber support external data logging via RS485 or Ethernet?
No—data export is limited to USB mass storage mode to ensure data integrity and eliminate network-related validation overhead. Integration with central monitoring systems requires external analog/digital signal interfaces (optional add-on).
