BOXUN BXY-400SI Pharmaceutical Stability Testing Chamber

Overview

The BOXUN BXY-400SI Pharmaceutical Stability Testing Chamber is an ICH-compliant environmental simulation system engineered for long-term and accelerated stability studies in accordance with ICH Q1A(R3), Q1B, Q5C, and relevant national pharmacopoeial requirements. It provides tightly controlled, reproducible temperature, relative humidity, and optional light exposure conditions—critical for evaluating the chemical and physical degradation kinetics of active pharmaceutical ingredients (APIs), drug products, and packaging systems over time. Designed to meet the stringent operational demands of GLP- and GMP-regulated laboratories, the chamber integrates precision climate control with robust data integrity architecture, enabling full traceability from test initiation through final report generation.

Key Features

• 7-inch high-resolution capacitive touchscreen interface running on Windows CE OS, supporting intuitive parameter configuration, real-time monitoring of setpoints and actual values (temperature, humidity, illumination status), elapsed time, active program stage, and system health indicators.
• Fuzzy PID-based dual-loop temperature and humidity control algorithm ensures high stability and rapid recovery (<15 min to re-stabilize after 30-sec door opening at 40 °C/75 %RH), minimizing experimental perturbation.
• 30-stage × 99-cycle programmable profile capability, with each stage configurable for duration (1–9999 h), temperature (−10–85 °C dry; 10–60 °C humidified), humidity (15–98 %RH), and optional light intensity (if equipped with UV/visible lamps).
• Energy-efficient refrigeration system featuring inverter-driven compressor and high-efficiency EC fans; C.H. (Cycle Heat) thermal recovery system recaptures waste heat from condensation to reduce heater duty cycle and improve energy utilization.
• Comprehensive safety and fault management: independent over-temperature cutoff (adjustable limit), door-open detection with audible/visual alert, low-water-level alarm for humidifier reservoir, sensor failure diagnostics, and automatic shutdown upon critical fault detection.
• Built-in non-volatile memory stores up to one million timestamped environmental readings (T/RH); USB port enables direct export of raw data logs and event history—including power-on/power-off events, parameter modifications, alarm triggers—with ISO 8601-formatted timestamps.

Sample Compatibility & Compliance

The BXY-400SI accommodates standard pharmaceutical sample configurations—including vials, blister packs, bottles, sachets, and stability trays—across four standard stainless-steel shelves (expandable to twelve). Its internal chamber volume (0.40 m³) supports ICH-defined storage capacities for long-term (25 °C/60 %RH), intermediate (30 °C/65 %RH), and accelerated (40 °C/75 %RH) testing protocols. The chamber complies with mechanical and electrical safety standards per GB/T 14710 and meets electromagnetic compatibility (EMC) requirements per GB/T 18268. Optional IQ/OQ/PQ documentation packages are available to support 21 CFR Part 11–compliant validation under GMP environments.

Software & Data Management

Data integrity is maintained via built-in audit trail functionality: all user actions—including login/logout, parameter changes, alarm acknowledgments, and manual overrides—are logged with operator ID, timestamp, and pre-/post-change values. Exported CSV files include metadata headers compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Optional FDA- and GMP-specific remote monitoring software provides centralized dashboard visualization, email/SMS alerts (via integrated GPRS module), electronic signature support, and automated report generation aligned with Annex 11 and EU GMP Annex 11 expectations.

Applications

• ICH Q1A(R3) long-term, accelerated, and stress stability testing of APIs and finished dosage forms
• Photostability assessment per ICH Q5C (when fitted with optional light source modules)
• Accelerated aging studies for primary and secondary packaging materials
• Real-time stability monitoring during clinical trial supply storage
• Reference standard storage under defined climatic conditions
• Environmental qualification of cleanroom-adjacent storage areas

FAQ

Does the BXY-400SI support 21 CFR Part 11 compliance?
Yes—when configured with optional FDA-compliant monitoring software, electronic signatures, and audit-trail-enabled hardware logging, it satisfies key technical controls for electronic records and signatures.
Can the chamber operate continuously at 40 °C/75 %RH for 6 months without maintenance?
Yes—the system is rated for uninterrupted operation under ICH-accelerated conditions; routine preventive maintenance (e.g., humidifier descaling, filter replacement) is recommended every 90 days per manufacturer guidelines.
Is third-party calibration certification included with purchase?
No—calibration certificates for temperature and humidity sensors (traceable to NIM or equivalent national metrology institutes) are available as optional add-ons, including multi-point verification at 0 °C, 60 °C, and 121 °C for temperature; and 15 °C/40 %RH, 20 °C/60 %RH, 30 °C/80 %RH for combined T/RH points.
What validation documentation is provided?
Standard delivery includes factory performance qualification (PQ) report; optional IQ/OQ/PQ protocol execution and summary reports—fully aligned with ASTM E2500 and ISPE GAMP5—are available upon request.
How is data security ensured during USB export?
Exported files are write-protected binary-CSV hybrids with embedded checksums; no editing capability is retained post-export, preserving data integrity for regulatory submission.
