YSEI SHH-220SD-2TA Drug Stability Testing Chamber

Overview

The YSEI SHH-220SD-2TA Drug Stability Testing Chamber is a precision-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 employs dual PID-controlled refrigeration, heating, and humidification subsystems to maintain highly stable temperature (±0.3 °C) and relative humidity (±2% RH) conditions across long-term (25 °C/60% RH), accelerated (40 °C/75% RH), and intermediate (30 °C/65% RH) test protocols. The chamber’s thermally insulated double-wall construction, low-noise scroll compressor, and optimized air circulation architecture ensure minimal thermal gradients (<0.5 °C uniformity) and exceptional reproducibility—critical for regulatory submission data integrity.

Key Features

• Triple-layer security architecture: Dual-lock outer door + tempered glass inner door + configurable access permission logging (optional)
• Intelligent energy management: Variable-frequency compressor control, adaptive defrost logic, and low-power standby mode reduce annual energy consumption by up to 28% versus conventional chambers
• Real-time acoustic optimization: Sound-dampened insulation and vibration-isolated mounting achieve ≤42 dB(A) operational noise—suitable for shared laboratory environments
• Touchscreen HMI with intuitive icon-based navigation: 7-inch capacitive display supports multi-language UI (English, Chinese, Spanish), calibration lockout, and context-sensitive help
• Redundant safety systems: Independent overtemperature cutoff (mechanical backup), dry-run protection for humidifier, high-pressure compressor shutdown, and real-time voltage/frequency monitoring

Sample Compatibility & Compliance

The SHH-220SD-2TA accommodates standard ICH-compliant sample trays (up to 220 L working volume), including nested vials, blister packs, and secondary packaging configurations. Internal airflow design minimizes turbulence-induced moisture migration between adjacent samples. All hardware and firmware comply with ISO 13485:2016 (Medical Devices Quality Management), ISO 9001:2015, and GLP audit requirements. Full IQ/OQ documentation packages—including traceable calibration certificates, sensor linearity reports, and installation verification checklists—are provided pre-delivery. System validation supports 21 CFR Part 11-compliant electronic records through configurable user roles, biometric or token-based authentication, and immutable audit trails.

Software & Data Management

The integrated SIMS (Stability Instrument Monitoring System) software enables centralized control of up to 30 units via LAN or secure cloud gateway. Data acquisition occurs at user-selectable intervals (1 min to 60 min), with primary storage on a 4 GB internal flash buffer and secondary archival on removable industrial-grade SD cards (formatted FAT32, up to 128 GB). Power-fail resilient memory preserves all logged parameters—including timestamped setpoints, actual readings, alarm states, and operator IDs—for ≥10 years. Export formats include CSV, PDF summary reports, and XML-compatible structured logs. Optional SMS alert integration delivers real-time notifications for temperature/humidity excursions, power loss, door open events, and maintenance due dates—configurable per device and user group.

Applications

• ICH Q1A(R3) long-term, accelerated, and stress testing of APIs and finished dosage forms
• Photostability assessment when integrated with optional UV/visible light modules (IEC 60068-2-5 compliant)
• Accelerated aging studies for packaging compatibility (e.g., blister seal integrity under cyclic RH)
• Reference standard storage under controlled conditions (USP )
• Stability-indicating method development support, including forced degradation condition screening

FAQ

Does the SHH-220SD-2TA meet FDA 21 CFR Part 11 requirements for electronic records?

Yes—the system implements role-based access control, electronic signatures, audit trail generation with tamper-evident hashing, and full export capability for regulatory review.
What is the maximum data retention period without external backup?

Internal memory retains 10 years of 1-minute interval data (timestamp, T/RH values, alarms, user actions) even after complete power loss.
Can the chamber be validated for GMP production environments?

Yes—YSEI provides IQ/OQ protocol templates, execution services, and certified calibration reports traceable to NIM (China National Institute of Metrology) standards.
Is remote firmware update supported?

Firmware updates are performed securely via encrypted USB drive or authenticated HTTPS upload; no unattended OTA updates are permitted per cybersecurity policy.
What environmental conditions are required for proper chamber operation?

Ambient temperature: 5–35 °C; relative humidity: ≤85% RH; ventilation: minimum 0.5 m² free area around rear panels; power supply: 220 V ±10%, 50 Hz, dedicated circuit with surge protection.
