YSEI SHH-500GSD-2TA Integrated Drug Stability Testing Chamber

Overview

The YSEI SHH-500GSD-2TA Integrated Drug Stability Testing Chamber is an engineered environmental simulation system designed specifically for pharmaceutical stability studies in accordance with international regulatory frameworks. It implements a multi-parameter controlled environment—simultaneously regulating temperature, relative humidity, visible light intensity, and UV irradiance—to replicate ICH-defined storage conditions including long-term (25°C/60% RH), accelerated (40°C/75% RH), intermediate (30°C/65% RH), and low-humidity (40°C/20% RH) protocols. Its architecture follows the fundamental principles of controlled-environment chamber design: forced-air convection for thermal uniformity, ultrasonic humidification with auto-refill and dry-run protection, dual-stage refrigeration with independent condensate management, and calibrated LED-based photometric arrays compliant with ICH Q1B spectral distribution requirements (320–400 nm UV-A + 400–800 nm visible). The chamber’s internal volume of 500 L supports standardized placement of stability batches per ICH guidance, while its structural insulation and sealed door gasket ensure ≤±0.5°C temperature deviation and ≤±3% RH fluctuation across the working zone under steady-state operation.

Key Features

• Quad-condition control: Independent, real-time regulation of temperature (0–70°C), relative humidity (10–95% RH), visible light (0–10,000 lux), and UV irradiance (0–200 W/m², 320–400 nm)
• Energy-optimized thermal management: High-efficiency scroll compressors with variable-speed EC fans and intelligent load-matching logic reduce average power draw by up to 22% versus conventional chambers
• Low-noise operation: Acoustic emission ≤52 dB(A) at 1 m distance, achieved via vibration-damped mounting, sound-absorbing chamber lining, and optimized airflow path design
• Integrated thermal print logging: Built-in micro-thermal printer with user-configurable interval (1 min–24 h), generating time-stamped, tamper-evident paper records compliant with ALCOA+ data integrity principles
• Comprehensive safety architecture: Dual independent temperature limiters (PID + mechanical backup), humidity sensor redundancy, compressor overcurrent/overheat detection, and automatic water-level cutoff for humidifier
• Remote alarm & supervision: GSM-enabled SMS alerting for temperature/humidity excursions, power failure, door open events, and system fault codes—scalable to centralized fleet monitoring via optional YSEI CloudLink gateway

Sample Compatibility & Compliance

The SHH-500GSD-2TA accommodates standard pharmaceutical packaging formats—including blister packs, HDPE bottles, glass vials, and IV bags—within its uniformly conditioned workspace. All internal surfaces are electropolished stainless steel (AISI 316L) to prevent corrosion and facilitate cleaning validation. The chamber meets the physical performance criteria outlined in ISO 16774:2018 (Environmental testing—Stability chambers) and adheres to the qualification requirements of FDA 21 CFR Part 11 for electronic records and signatures when paired with YSEI’s validated IQ/OQ documentation package. Its environmental profiles are preconfigured to satisfy ICH Q1A(R3) tiered testing strategies and support bracketing/matrixing study designs. For biologics and sterile products requiring stringent particulate control, optional HEPA-filtered recirculation mode (ISO Class 8) is available as a factory-installed upgrade.

Software & Data Management

The embedded YSEI STS-OS v4.2 firmware provides full audit trail functionality with immutable event logs, user role-based access control (admin/operator/auditor), and electronic signature capability compliant with Annex 11 and 21 CFR Part 11. All measurement data—including setpoints, actual values, alarms, and calibration history—are stored internally on encrypted SD card and exportable in CSV or PDF format. Optional YSEI DataVault software enables automated report generation (stability summary, trend analysis, out-of-specification flagging), integration with LIMS via ASTM E1384-compliant HL7 messaging, and secure cloud backup with TLS 1.3 encryption. Raw data files retain native timestamp resolution (1-second intervals) and include metadata such as sensor ID, calibration due date, and operator login token.

Applications

• I CH Q1A(R3) long-term, accelerated, and intermediate condition studies for small-molecule APIs and finished dosage forms
• ICH Q1B photostability testing per Option 1 (open sample exposure) and Option 2 (sample-in-package)
• Low-humidity stress testing for large-volume parenterals (e.g., 40°C/20% RH per USP )
• Real-time stability monitoring during clinical trial material storage and commercial batch release
• Forced degradation studies supporting ICH Q5C comparability assessments
• Environmental qualification of cold-chain packaging systems (when operated in temperature-only mode)

FAQ

Does the SHH-500GSD-2TA support 21 CFR Part 11 compliance out of the box?

Yes—when configured with the optional YSEI DataVault software and executed with documented IQ/OQ protocols, the system satisfies electronic record and signature requirements including audit trails, role-based permissions, and electronic signatures.
Can the chamber maintain 40°C/20% RH reliably for extended durations?

Yes—the dual-stage dehumidification system (refrigerative + desiccant-assisted) achieves and sustains ≤20% RH at 40°C with ±1.5% RH accuracy over 90-day continuous operation, verified per GB/T 10586–2025 Annex D.
Is third-party calibration certification included with delivery?

Factory calibration certificates traceable to NIM (National Institute of Metrology, China) are provided; ISO/IEC 17025-accredited on-site calibration services are available as a post-delivery option.
What is the warranty coverage and service response time?

Standard warranty is 12 months from commissioning acceptance; emergency onsite technical support is available within 72 hours in Tier-1 cities across Asia-Pacific, subject to service agreement terms.
How is photometric uniformity validated across the chamber volume?

Each unit undergoes spatial mapping using NIST-traceable spectroradiometers at 9 defined grid points per shelf level, ensuring irradiance deviation ≤±5% of setpoint across the entire test zone per ICH Q1B Section 3.2.
