Overview
The YSEI SHH-800SD-2T Drug Stability Testing Chamber is an engineered environmental simulation system designed specifically for pharmaceutical stability studies in compliance with ICH Q1–Q5 guidelines, USP , FDA 21 CFR Part 11, and Chinese Pharmacopoeia requirements. It implements precise, long-term control of temperature (±0.3 °C) and relative humidity (±2.5% RH) across defined test conditions—including long-term (25 °C/60% RH), accelerated (40 °C/75% RH), intermediate (30 °C/65% RH), and low-humidity protocols (e.g., 40 °C/20% RH for large-volume parenterals). The chamber utilizes dual independent PID-controlled refrigeration and humidification circuits, coupled with a high-efficiency air circulation system featuring laminar airflow distribution and minimal thermal/hygrometric gradients (<±0.5 °C / <±3% RH across working volume). Its structural architecture integrates stainless steel 304 inner chamber walls, double-glazed observation doors with anti-fog coating, and insulated polyurethane foam (≥120 mm thickness) to ensure thermal stability and energy efficiency.
Key Features
- Touchscreen HMI controller with 64 MB onboard cyclic memory and removable SD card slot—stores setpoints, real-time sensor values, timestamps, and event logs at user-configurable intervals (1 min minimum; supports >10 years of continuous logging at 1-min resolution)
- Electronic data integrity compliant with FDA 21 CFR Part 11: audit trail enabled, electronic signatures supported, role-based access control, and immutable record generation
- Dual-door design: outer keyed security door prevents unauthorized access; inner tempered glass door minimizes thermal disturbance during visual inspection
- RS485 Modbus RTU interface for centralized monitoring—enables connection of up to 30 units to a single host PC via daisy-chained topology
- Remote supervision capability via SIMS software over LAN/WAN or Internet—supports real-time parameter adjustment, alarm acknowledgment, and firmware updates without on-site presence
- Multi-layer safety architecture: independent overtemperature cutoff, humidifier dry-run protection, compressor overload relay, and optional GSM-based SMS alerting for power failure or excursion events
- Ultra-low noise operation (<55 dB[A] at 1 m) achieved through vibration-damped compressor mounting and acoustic insulation
Sample Compatibility & Compliance
The SHH-800SD-2T accommodates standard ICH-compliant stability storage configurations—including open trays, sealed containers, blister packs, vials, and IV bags—within its 800 L working volume. Internal dimensions (D×W×H) support flexible rack integration per WHO TRS 992 Annex 6 and EU GMP Annex 15 guidance. All materials in contact with the chamber environment meet USP Class VI biocompatibility standards. The system is validated per ISO 14644-1 (Class 8 cleanroom-compatible airflow), and its qualification documentation package includes full IQ/OQ protocols aligned with ASTM E2500-13 and ISPE Good Practice Guide for Equipment Qualification. Calibration traceability follows ISO/IEC 17025 requirements through NIST-traceable reference sensors.
Software & Data Management
YSEI’s proprietary Stability Data Manager (SDM) software provides secure, encrypted local or networked data acquisition, visualization, and reporting. It generates ALCOA+ compliant records—including raw sensor outputs, calibration history, user activity logs, and deviation annotations—with automated PDF report generation for regulatory submissions. Data export formats include CSV, XML, and PDF/A-2b for archival. The software supports 21 CFR Part 11 compliance modules: electronic signature workflows, automatic audit trail archiving, and configurable retention policies (default: 36 months, extendable per client SOP). Integration with LIMS and MES systems is available via OPC UA or RESTful API.
Applications
- I CH Q1A(R3) long-term, accelerated, and intermediate condition testing for small-molecule APIs and finished dosage forms
- ICH Q5C biologics stability assessment under controlled humidity profiles
- Photostability pre-screening (when integrated with optional ICH Q1B-compliant light banks)
- Accelerated aging studies for packaging compatibility (blister, HDPE, glass)
- GMP-regulated stability program execution in QC laboratories and contract research organizations (CROs)
- Regulatory submission support for ANDA, NDA, and MAA dossiers requiring documented environmental control evidence
FAQ
Does the SHH-800SD-2T comply with FDA 21 CFR Part 11 for electronic records?
Yes—the system includes full electronic signature capability, audit trail functionality, and data immutability features certified per Part 11 Annex A guidance.
Can multiple chambers be managed from one computer?
Yes—up to 30 units can be daisy-chained via RS485 and monitored centrally using SDM software or third-party SCADA platforms.
What validation documentation is provided?
Standard delivery includes IQ/OQ protocols, executed reports, calibration certificates, and a URS-aligned verification summary—all formatted per ASTM E2500 and EU Annex 15 expectations.
Is remote troubleshooting supported?
Yes—via SIMS remote desktop interface over secure TLS-encrypted connections, enabling diagnostics, parameter tuning, and log retrieval without physical access.
What is the maximum data retention capacity of the internal memory?
At 1-minute sampling interval, the 64 MB embedded memory stores approximately 10 years of time-stamped operational data; external SD card extends this indefinitely.
