YSEI SHH-150GSD Comprehensive Drug Stability Testing Chamber

Overview

The YSEI SHH-150GSD Comprehensive Drug Stability Testing Chamber is an engineered environmental simulation system designed specifically for pharmaceutical stability studies in compliance with ICH guidelines (Q1A[R3], Q1B, Q5C), the Chinese Pharmacopoeia (2020 Edition, General Chapter ), and ASTM E2375-22. It provides precise, independent control of temperature (0–60 °C), relative humidity (10–95 %RH at 25 °C), and photometric illumination (0–10,000 lx, UV-filtered LED cold-light source) within a single 150 L stainless-steel chamber. Unlike modular or single-parameter chambers, the SHH-150GSD integrates all three critical stress variables—thermal, hygric, and photic—into one validated platform, eliminating inter-unit variability and reducing footprint and operational complexity. Its architecture supports long-term (25 °C/60 %RH), accelerated (40 °C/75 %RH), intermediate (30 °C/65 %RH), and low-humidity (40 °C/20 %RH) protocols required for parenteral solutions, lyophilized products, and moisture-sensitive APIs.

Key Features

• Triple-parameter precision control: Simultaneous regulation of temperature, humidity, and illumination—each independently adjustable and continuously monitored via calibrated Pt100 sensors and digital lux meters.
• Energy-optimized refrigeration and humidification: Hermetically sealed compressor with variable-speed drive and high-efficiency desiccant-assisted dehumidification ensure stable low-RH operation (e.g., 40 °C/20 %RH) without condensation or thermal overshoot.
• Acoustic engineering: Sound-dampened insulation and vibration-isolated compressor mounting achieve ≤55 dB(A) at 1 m—suitable for shared laboratory environments and GMP cleanroom-adjacent placement.
• Real-time traceability: Integrated thermal printer outputs time-stamped, tamper-evident paper records of temperature/humidity profiles; configurable print intervals (1 min to 24 h) support ALCOA+ data integrity principles.
• Redundant safety architecture: Independent overtemperature cutoff (dual-stage), dry-run protection for humidifier reservoir, compressor current overload sensing, and optional GSM-based SMS alerting for power failure or parameter excursion beyond user-defined thresholds.

Sample Compatibility & Compliance

The SHH-150GSD accommodates standard USP/ICH-compliant sample racks, including stacked trays and light-shielded vial holders. One removable photosensitive shelf (marked *) enables ICH Q1B photostability testing under controlled irradiance (optionally equipped with radiometric calibration kit). All materials in contact with the chamber interior—304 stainless steel walls, silicone gaskets, and non-outgassing insulation—are compliant with ISO 10993-5 (cytotoxicity) and USP . The system supports full qualification documentation: pre-validated IQ/OQ protocols aligned with FDA 21 CFR Part 11 Annex 11 and EU GMP Annex 15 requirements—including audit trails, electronic signatures, and version-controlled SOPs.

Software & Data Management

While the SHH-150GSD operates autonomously via its embedded 7-inch capacitive touchscreen HMI, optional Ethernet/Wi-Fi connectivity enables remote monitoring via YSEI’s StabilityLink™ software (Windows/Linux compatible). This application logs all sensor data at 10-second intervals, generates real-time trend plots, exports CSV/Excel reports with metadata (operator ID, protocol ID, chamber ID), and maintains immutable audit trails meeting GLP/GMP record retention mandates (≥25 years). Data encryption (AES-256) and role-based access control ensure compliance during regulatory inspections.

Applications

• ICH-aligned stability protocols: Long-term, accelerated, intermediate, and stress-condition studies per Q1A(R3) and Q5C.
• Photostability assessment: Forced degradation under UV/visible light per Q1B, including comparison of protected vs. unprotected samples.
• Excipient compatibility screening: Monitoring physical changes (crystallization, deliquescence, discoloration) under controlled RH gradients.
• Container-closure integrity validation: Evaluating moisture ingress rates in blister packs, vials, and prefilled syringes across humidity ramps.
• Biologics and mRNA formulation stability: Low-temperature (2–8 °C) and freeze-thaw cycling with humidity control to assess protein aggregation kinetics.

FAQ

Does the SHH-150GSD meet FDA 21 CFR Part 11 requirements for electronic records?
Yes—when used with StabilityLink™ software and configured with electronic signatures, audit trail logging, and secure user authentication, it satisfies Part 11 technical and procedural controls.
Can the chamber maintain 40 °C and 20 %RH simultaneously for large-volume parenteral stability testing?
Yes—its dual-mode dehumidification (refrigerative + desiccant assist) achieves and sustains this low-RH condition with ±0.5 °C/±3 %RH accuracy over 72-hour continuous operation.
Is IQ/OQ documentation included with purchase?
A complete, editable IQ/OQ protocol package—including test scripts, acceptance criteria, and blank execution worksheets—is provided at no additional cost; YSEI-certified engineers can perform on-site qualification upon request.
What is the expected service life and maintenance interval?
Designed for ≥15 years of continuous operation; preventive maintenance (compressor oil check, sensor calibration, gasket inspection) is recommended every 12 months or 2,000 operating hours.
How does the SMS alarm system integrate with multi-chamber facilities?
Each unit is assigned a unique device ID; the GSM module supports centralized alert routing to designated lab managers’ mobile numbers or email-to-SMS gateways, enabling scalable fleet monitoring without third-party platforms.
