Boxun BXS-150 Expandable Drug Stability Testing Chamber

Overview

The Boxun BXS-150 Expandable Drug Stability Testing Chamber is an ISO/ICH-compliant environmental simulation system engineered for long-term, accelerated, and stress-condition stability studies of pharmaceutical products in accordance with ICH Q1A(R3), Q1B, Q5C, and relevant sections of USP , , and FDA Guidance for Industry on Stability Testing of Drug Substances and Products. It operates on a precision-controlled tri-modal conditioning architecture—simultaneously regulating temperature, relative humidity, and photometric or ultraviolet irradiance—to replicate the defined storage conditions required for bracketing, real-time, and forced degradation protocols. The chamber employs a dual-wall insulated stainless-steel inner chamber with C.H. (Circulating Heat) thermal recovery system, minimizing thermal inertia and enabling rapid stabilization after door openings. Its core thermodynamic control relies on a variable-frequency refrigeration circuit paired with PID-based fuzzy logic algorithms, ensuring stable setpoint maintenance across all operational modes—even during multi-segment programmable cycles.

Key Features

• 4.3-inch TFT 16-bit true-color LCD touchscreen interface running on Windows CE OS with high-frequency CPU and extended onboard memory (≥256 MB)
• 30-segment, 99-cycle programmable controller supporting time-based and cumulative-dose-based termination (e.g., Lux·hr or W·hr/m²)
• Imported energy-efficient hermetic compressor and high-static-pressure centrifugal blower for uniform air distribution and low-noise operation
• Real-time data logging: stores up to 250,000 timestamped records; displays latest 1,600 entries directly on screen
• Multi-interface connectivity: USB 2.0 (for data export and firmware updates), RS232, and RS485 (Modbus RTU protocol support)
• Integrated thermal and mechanical safety suite: over-temperature cutoff, door-open alarm, sensor fault detection, water-level monitoring, and password-protected screen lock
• Standard embedded thermal printer for immediate hardcopy of calibration logs, alarm events, and cycle summaries
• C.H. heat-recycling system improves heating efficiency by reusing residual chamber heat, reducing warm-up time by up to 35% versus conventional designs

Sample Compatibility & Compliance

The BXS-150 accommodates standard pharmaceutical packaging formats—including blister packs, HDPE bottles, glass vials, and aluminum pouches—across three adjustable stainless-steel shelves (standard), expandable to four. Its internal volume (150 L) and optimized airflow design meet ICH-defined uniformity requirements: ±1.0 °C temperature uniformity and ±3% RH uniformity (at 25 °C / 60% RH). All configurations comply with GMP Annex 15 validation principles and support full 3Q (IQ/OQ/PQ) documentation packages upon request. Optional FDA 21 CFR Part 11–compliant software enables electronic signatures, audit trails, and role-based access control. Humidity and photostability modules are validated per ASTM E2050 (light exposure) and ISO 12048 (humidity generation), ensuring traceable compliance with regulatory submission requirements.

Software & Data Management

Data integrity is maintained via dual-path logging: internal flash memory (non-volatile, battery-backed) and external USB export in CSV/Excel-compatible format. Event logs include timestamps for power-on/off, parameter changes, alarm triggers (with severity codes), and door openings. Optional FDA Edition or GMP Edition monitoring software provides remote supervision via Ethernet or Wi-Fi (with optional GPRS SMS alert module), configurable alarm thresholds, automated report generation (PDF/HTML), and full ALCOA+ adherence—including attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available records. All software modules support electronic signature workflows compliant with 21 CFR Part 11 Annex 11.

Applications

• ICH Q1A(R3)-aligned long-term stability studies (25 °C / 60% RH, 30 °C / 65% RH)
• Accelerated testing per Q1B (40 °C / 75% RH, 50 °C dry)
• Photostability assessment under ICH Q1B Option 1 (near-UV: 200 W·hr/m², 320–400 nm) and Option 2 (visible light: ≥1.2 × 10⁶ Lux·hr)
• Forced degradation studies including thermal, oxidative, and hydrolytic stress profiling
• Excipient compatibility screening and formulation robustness evaluation
• Biological product storage condition mapping (e.g., 2–8 °C + humidity control variants)
• Environmental stress qualification for packaging components and primary containers

FAQ

Does the BXS-150 meet ICH Q1B photostability requirements?
Yes—the optional LED-based illumination module delivers 0–10,000 Lux (±500 Lux accuracy) with real-time Lux·hr accumulation and auto-shutoff; the UV module emits 0–2 W/m² within 320–400 nm band, satisfying near-UV energy thresholds.
Can humidity and light be operated simultaneously?
Yes—humidity + photostability configuration supports concurrent operation at 10–70 °C, 30–95% RH, and 0–10,000 Lux without performance compromise.
Is 3Q validation documentation included?
A comprehensive IQ/OQ/PQ protocol package compliant with EU GMP Annex 15 and ASTM E2500 is available as an optional add-on, including test scripts, acceptance criteria, and executed reports.
What calibration certificates are provided?
Factory-calibrated sensors include NIST-traceable certificates for temperature (0 °C, 60 °C, 121 °C), humidity (15 °C/40% RH, 20 °C/60% RH, 30 °C/80% RH), and irradiance (Lux and UV W/m²).
How is data security ensured during remote monitoring?
FDA/GMP software options implement TLS 1.2 encryption, session timeouts, multi-factor authentication, and immutable audit trails meeting 21 CFR Part 11 §11.10 and Annex 11 §6.2 requirements.
