YSEI SHH-SSGD-2TA Multi-Chamber Drug Stability Testing System

Overview

The YSEI SHH-SSGD-2TA Multi-Chamber Drug Stability Testing System is an engineered solution for ICH Q1–Q5-compliant stability studies in pharmaceutical development, manufacturing, and quality control laboratories. Designed according to the principles of controlled environmental simulation, it enables simultaneous execution of long-term (e.g., 25°C/60% RH), accelerated (e.g., 40°C/75% RH), intermediate (e.g., 30°C/65% RH), and stress-condition (e.g., 40°C/20% RH for large-volume parenterals) testing protocols across independent climatic chambers. Each chamber operates with thermodynamic autonomy—maintaining precise, traceable temperature (±0.5°C) and humidity (±3% RH) profiles over extended durations—ensuring data integrity required for regulatory submissions to FDA, EMA, PMDA, and NMPA. The system’s architecture integrates dual-sensor feedback loops, PID-controlled refrigeration and humidification subsystems, and insulated double-door access to minimize thermal/hygrometric perturbation during routine observation.

Key Features

• Multi-chamber independence: Up to two fully isolated test chambers, each programmable with distinct temperature (0–70°C) and relative humidity (10–95% RH) setpoints
• Centralized control & remote supervision: Unified software interface supports concurrent monitoring and configuration of up to 30 YSEI stability units via LAN or internet-connected RS485 network
• Triple-layer data recording: (1) Real-time USB/RS485-exported digital logs; (2) Internal 64 MB circular memory storing setpoint, actual value, timestamp, and date (configurable sampling interval from 1 min to 24 h); (3) Optional thermal printer with adjustable print frequency for audit-ready hardcopy
• Energy-optimized operation: High-efficiency compressors, low-power Peltier-assisted dehumidification, and intelligent fan modulation reduce average power consumption by ≥35% versus conventional single-chamber systems
• Acoustic engineering: Noise emission <52 dB(A) at 1 m distance ensures compatibility with quiet laboratory environments
• Dual-glass door design: Tempered inner door provides full visual access without compromising chamber stability; outer keyed lock prevents unauthorized access per GMP Annex 11 and WHO TRS 992 requirements
• Comprehensive safety architecture: Independent overtemperature cutoff, dry-run protection for humidifier reservoirs, compressor overload sensing, and SMS-based alarm notification (temperature/humidity deviation, power failure)

Sample Compatibility & Compliance

The SHH-SSGD-2TA accommodates a broad range of pharmaceutical dosage forms—including tablets, capsules, injectables, ointments, lyophilized powders, and IV bags—without cross-chamber contamination risk. Its environmental control fidelity meets ICH Q1A(R2), Q1B, Q5C, and USP specifications for stability-indicating conditions. Humidity capability down to 10% RH satisfies specialized requirements for moisture-sensitive biologics and large-volume parenteral formulations. All operational parameters are logged with time-stamped, immutable records supporting ALCOA+ principles. System validation documentation—including IQ/OQ protocols aligned with ASTM E2500-13 and EU GMP Annex 15—is provided upon request.

Software & Data Management

The embedded controller runs firmware compliant with FDA 21 CFR Part 11 requirements, featuring role-based user authentication, electronic signatures, and full audit trail functionality (including parameter changes, alarm events, and manual interventions). Data export formats include CSV and XML for seamless integration into LIMS, ELN, or statistical analysis platforms (e.g., JMP, Minitab). Remote diagnostics and firmware updates are supported via secure HTTPS tunneling. SD card data retrieval preserves raw sensor output for retrospective review—critical for root cause analysis during OOS investigations.

Applications

• ICH-aligned long-term and accelerated stability studies for registration dossiers
• Forced degradation studies under oxidative, photolytic, thermal, and hydrolytic stress conditions
• Real-time shelf-life determination and retest date establishment
• Excipient compatibility screening and formulation robustness assessment
• Teaching and training in pharmaceutical sciences curricula requiring reproducible environmental exposure
• Support for GMP batch release decision-making and annual product review (APR) data packages

FAQ

Does the SHH-SSGD-2TA support 20% RH at 40°C for large-volume parenteral stability testing?
Yes. The system achieves and maintains 40°C ±0.5°C / 20% RH ±3% RH continuously, validated per ICH Q1B photostability annex and USP low-humidity protocol requirements.
Can data from multiple SHH-SSGD-2TA units be aggregated into a single database?
Yes. Using the optional YSEI StabilityLink™ software suite, synchronized timestamped data from up to 30 units can be imported, filtered, and trend-analyzed in real time.
Is the system suitable for GLP-regulated laboratories?
Yes. With optional IQ/OQ documentation, Part 11-compliant audit trails, and calibrated sensor certificates traceable to NIST standards, it fulfills GLP OECD 1998 and FDA GLP regulations.
What is the maximum continuous runtime supported by the internal data logger?
At 1-minute sampling interval, the 64 MB internal memory stores >10 years of timestamped temperature/humidity values, setpoints, and event flags.
Are replacement parts and technical support available outside China?
Yes. YSEI maintains authorized service partners in North America, EU, and APAC regions, offering on-site calibration, preventive maintenance, and spare parts logistics with ≤72-hour lead time.
