Boxun BXY-150I Pharmaceutical Stability Testing Chamber

Overview

The Boxun BXY-150I Pharmaceutical Stability Testing Chamber is an ICH-compliant environmental simulation system engineered for long-term and accelerated stability studies of pharmaceutical products in accordance with ICH Q1A(R2), Q1B, Q5C, and relevant sections of USP , EP 2.2.42, and ISO 14644-3. It provides tightly controlled, reproducible temperature (0–70 °C), relative humidity (25–95 %RH), and optional light exposure conditions required to assess chemical degradation kinetics, physical changes, and shelf-life prediction under defined stress and storage scenarios. Designed for GLP- and GMP-regulated environments, the chamber integrates precision thermodynamic control architecture—including a variable-frequency refrigeration system, C.H. (Cycle Heat) energy recovery loop, and high-stability humidity generation—ensuring minimal thermal overshoot, rapid recovery after door opening (<15 min to re-stabilize at 40 °C/75 %RH), and low drift across extended test durations (≥6 months).

Key Features

• 4.3-inch TFT LCD touchscreen interface with 16-bit true color display, running on Windows CE OS with high-frequency CPU and expandable memory for robust multi-tasking
• Fuzzy PID + multi-stage programmable logic: supports up to 30 segments × 99 cycles, enabling complex ICH Zone IVb or bracketed storage profiles (e.g., 25 °C/60 %RH → 30 °C/65 %RH → 40 °C/75 %RH)
• Imported high-efficiency hermetic compressor and EC centrifugal blower ensure stable airflow distribution and low acoustic noise (<55 dB(A))
• High-accuracy capacitive humidity sensor (±1.5 %RH typical accuracy) and PT1000 temperature sensors traceable to NIST standards
• Real-time data logging: 250,000-point internal memory with time-stamped records (resolution: 1 min); last 1600 entries viewable directly on screen
• Comprehensive safety architecture: dual independent overtemperature cutoffs, door-open alarm, low-water-level detection, sensor fault diagnostics, and automatic shutdown on critical failure
• USB port enables direct export of raw data logs (.csv), event history (power-on/off, parameter edits, alarms), and audit trails with ISO 8601 timestamps
• RS485 Modbus RTU interface for integration into centralized facility monitoring systems (e.g., Siemens Desigo, Honeywell Experion)

Sample Compatibility & Compliance

The BXY-150I accommodates standard pharmaceutical packaging formats—including blister cards, HDPE bottles, glass vials, and secondary cartons—on three adjustable stainless-steel shelves (expandable to four). Its uniform airflow design (validated per ASTM E2234) ensures spatial temperature deviation ≤±1 °C and humidity variation ≤±3 %RH across the full working volume. The chamber meets mechanical and electrical safety requirements per IEC 61010-1 and carries CE marking. Optional IQ/OQ/PQ documentation packages align with Annex 15 (EU GMP), FDA Guidance for Industry: Process Validation, and WHO TRS 986 Annex 6, supporting regulatory submissions and inspection readiness. All optional wireless loggers include factory calibration certificates (3-point temperature: 0 °C, 60 °C, 121 °C; 3-point RH: 15 °C/40 %RH, 20 °C/60 %RH, 30 °C/80 %RH).

Software & Data Management

Embedded firmware supports 21 CFR Part 11–ready operation when paired with FDA/GMP edition monitoring software (optional). This includes role-based user authentication, electronic signatures, immutable audit trails, and configurable alarm escalation (email/SMS via GPRS module). Data exports comply with ALCOA+ principles: Attributable, Legible, Contemporaneous, Original, Accurate, and Complete. Raw .csv files are compatible with JMP, Minitab, and WinNonlin for Arrhenius modeling and degradation pathway analysis. The embedded thermal printer provides immediate hard-copy output of current setpoints, real-time readings, and alarm summaries—fully compliant with paper-based backup requirements in hybrid validation environments.

Applications

• ICH Q1A(R2) long-term (25 °C/60 %RH) and accelerated (40 °C/75 %RH) stability testing of APIs and finished dosage forms
• Photostability assessment per ICH Q5C using optional UV/visible light modules (IEC 60068-2-5 compliant)
• Forced degradation studies (thermal, oxidative, hydrolytic) under non-ambient conditions
• Storage condition qualification for cold chain intermediates (e.g., 5 °C/60 %RH)
• Biologics stability evaluation at elevated temperatures to model real-world transport excursions
• Method suitability verification for dissolution, assay, and impurity testing protocols

FAQ

Does the BXY-150I support 21 CFR Part 11 compliance?
Yes—when configured with the optional FDA Edition monitoring software and enabled user access controls, electronic signatures, and audit trail archiving.
Can the chamber be validated for GMP use?
Yes—Boxun provides IQ/OQ/PQ protocol templates and executed reports aligned with EU Annex 15 and ASTM E2500, including mapping studies and sensor calibration certificates.
What is the recovery time after door opening?
At 40 °C/75 %RH, the chamber restores setpoint conditions within ≤14 minutes (measured per ASTM E2234 Section 7.5).
Is remote monitoring supported?
Yes—via RS485 Modbus integration or optional GPRS module for SMS alerts on temperature/humidity excursions, power loss, or door status.
Are calibration services included?
Factory calibration certificates are provided with all optional wireless loggers; on-site UKAS-accredited calibration is available as a separate service contract.
