Jihepu BSC-800 Temperature and Humidity Controlled Chamber for Pharmaceutical Stability Testing

Overview

The Jihepu BSC-800 Temperature and Humidity Controlled Chamber is an ICH-compliant environmental test system engineered for long-term stability studies of pharmaceuticals, biologics, and medical devices in accordance with ICH Q1A(R2), Q5C, and Q5D guidelines. It employs a dual-loop PID control architecture for independent regulation of temperature and relative humidity, utilizing high-stability platinum resistance sensors (Pt100) for temperature and capacitive polymer humidity sensors calibrated traceably to NIST standards. The chamber maintains thermodynamic equilibrium through a balanced air circulation system featuring centrifugal fans and a proprietary multi-directional airflow duct design—ensuring uniform thermal distribution and minimizing vertical/horizontal gradients across the working volume. Its sealed, corrosion-resistant stainless-steel interior (mirror-finish 304 SS) and electrostatically coated cold-rolled steel exterior support GMP-aligned cleaning protocols and extended operational integrity under continuous 24/7 operation.

Key Features

• Integrated refrigeration system with internationally certified hermetic compressors and R134a-free eco-friendly refrigerant (R600a), compliant with EU F-Gas Regulation (EU No. 517/2014)
• Patented auto-defrost mechanism operating without power interruption or thermal disturbance—enabling uninterrupted stability runs exceeding 180 days
• Dual-glass observation window with double-door structure: outer tempered safety glass + inner insulated acrylic; minimizes thermal leakage during visual inspection
• Modular shelving system with six independently adjustable 304 stainless-steel trays (load capacity: 15 kg per shelf), compatible with ISO-standard stability trays and vial racks
• Front-access 60 mm OD / 30 mm ID test ports on left and right walls for real-time probe insertion, sensor calibration, or external monitoring integration
• Intelligent microprocessor controller with 7-inch color TFT-LCD interface, supporting user-defined alarm thresholds, event logging, and password-protected parameter modification
• Power failure recovery function with non-volatile memory retention—preserves setpoints, program sequences, and runtime data during grid interruption

Sample Compatibility & Compliance

The BSC-800 accommodates standard ICH stability storage configurations—including open trays, closed containers, blister packs, and primary packaging assemblies—without compromising humidity homogeneity. Its internal volume (0.79 m³) meets WHO TRS 992 Annex 5 requirements for minimum air exchange ratio (≥10 air changes/hour) and supports concurrent placement of ≥200 x 10 mL amber glass vials. All materials in contact with the test environment comply with USP for plastic components and ISO 10993-5 cytotoxicity testing. The system is designed for use in GLP-certified laboratories and supports full audit trail generation required under FDA 21 CFR Part 11 when paired with validated data acquisition software.

Software & Data Management

Equipped with standard RS-485 Modbus RTU communication protocol, the BSC-800 integrates seamlessly with laboratory information management systems (LIMS), SCADA platforms, or standalone validation-grade data loggers. Optional accessories include a thermal printer module (supporting time-stamped trend curve output per ICH Q5C Annex 2), GPRS-based SMS alerting for out-of-specification excursions (±0.3 °C or ±3 %RH deviation), and Ethernet-enabled remote monitoring via web browser or mobile application. All data files are timestamped, digitally signed, and stored in CSV/Excel-compatible format with SHA-256 hash verification to satisfy ALCOA+ principles.

Applications

• ICH Q1A(R2) long-term (25 °C/60 %RH) and accelerated (40 °C/75 %RH) stability testing of APIs and finished dosage forms
• Accelerated aging studies for sterile barrier systems per ISO 11607-1 and ASTM F1980
• Hygroscopicity assessment of excipients and lyophilized formulations
• Real-time shelf-life determination for vaccines, monoclonal antibodies, and mRNA-lipid nanoparticle products
• Environmental stress screening of electronic medical devices per ISO 14971 risk management framework

FAQ

Does the BSC-800 meet ICH Q1A(R2) temperature and humidity tolerances for stability chambers?

Yes—the system maintains ±0.5 °C temperature fluctuation and ±5 %RH humidity fluctuation over the full operating range, satisfying ICH’s defined acceptance criteria for long-term and intermediate condition storage.

Can the chamber be qualified for GMP environments?

Yes—its design supports IQ/OQ/PQ execution per ASTM E2500 and EU Annex 15. Documentation packages include factory calibration certificates, sensor traceability reports, and FAT/SAT protocols.

Is remote access possible without third-party hardware?

The base unit includes RS-485 only; Ethernet or Wi-Fi connectivity requires optional communication gateway modules, which are supplied with preconfigured firmware and cybersecurity hardening per IEC 62443-3-3.

What is the maximum permissible load weight per shelf?

Each of the six adjustable shelves supports up to 15 kg uniformly distributed load, verified per EN 61000-6-3 EMC emission standards under full loading conditions.

How often does the humidity sensor require recalibration?

Capacitive humidity sensors are factory-calibrated and maintain ±2 %RH accuracy for 12 months under continuous operation; annual recalibration against saturated salt solutions (e.g., Mg(NO₃)₂, NaCl) is recommended per ISO/IEC 17025.
