YSEI SHH-3000SD-2T Drug Stability Testing Chamber

Overview

The YSEI SHH-3000SD-2T Drug Stability Testing Chamber is an engineered environmental simulation system designed exclusively for pharmaceutical stability studies in compliance with ICH Q1–Q5 guidelines, USP , and FDA 21 CFR Part 11 requirements. It operates on a precision-controlled dual-loop HVAC architecture—separately regulating temperature (±0.3 °C uniformity), relative humidity (±2.5 % RH uniformity), and air exchange rate—to maintain stable test conditions across 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 chamber construction features double-wall insulation with vacuum-sealed tempered glass inner doors, minimizing thermal load disturbance during visual inspection and ensuring data integrity per ICH Q5C photostability interface considerations. The unit is validated to support bracketing and matrixing study designs and meets the mechanical reliability benchmarks required for continuous 24/7 operation over multi-year stability programs.

Key Features

• Redundant microprocessor-based touch-screen controller with 64 MB internal circular buffer and removable industrial-grade SD card (≥32 GB preformatted FAT32) for secure, tamper-evident data logging
• Configurable sampling interval from 1 minute to 24 hours; default 15-minute logging supports ≥3 years of continuous timestamped records (date, time, setpoint, actual T/RH, alarm status)
• RS485 Modbus RTU interface enabling centralized monitoring of up to 30 units via single PC host using YSEI SimsLab™ v4.2 software
• Dual-door structure: outer keyed mechanical lock (ANSI/BHMA A156.13 Grade 2) + inner laminated low-E glass door with anti-fog coating for non-intrusive observation without chamber perturbation
• Energy-optimized refrigeration circuit with variable-speed EC fans and adaptive defrost logic—measured power consumption ≤1.8 kW at 40 °C/75 % RH steady state
• Acoustic enclosure design achieving ≤52 dB(A) at 1 m distance under full-load operation, suitable for shared laboratory environments
• Independent safety layers: chamber overtemperature cutoff (mechanical backup), humidifier dry-run protection, compressor high-pressure shutdown, and optional GSM-based SMS alert module (configurable thresholds for T/RH deviation, power loss, door breach)

Sample Compatibility & Compliance

The SHH-3000SD-2T accommodates standard ICH-compliant stability storage configurations—including open trays, sealed aluminum pouches, blister packs, and IV bags—within its 3000 L working volume (D1200 × W1000 × H2500 mm). Its airflow pattern (top-down, rear-to-front laminar sweep at 0.25 m/s ±15 %) ensures uniform exposure per ISO 14644-1 Class 8 cleanroom-equivalent particulate control. All materials contacting the chamber interior (304 stainless steel walls, silicone gaskets, anodized aluminum shelves) comply with USP extractables profiling standards. Full IQ/OQ documentation packages—including sensor calibration certificates traceable to NIM (National Institute of Metrology, China), protocol templates aligned with ASTM E2500-13, and electronic audit trail configuration—are provided with each unit. System validation supports GxP-regulated environments operating under cGMP Annex 11 and EU GMP Annex 15 frameworks.

Software & Data Management

SimsLab™ v4.2 software delivers 21 CFR Part 11–compliant data governance: role-based user authentication (LDAP integration optional), electronic signatures with biometric or token-based second-factor verification, immutable raw-data archives (SHA-256 hashed .CSV/.PDF exports), and configurable audit trail filtering (e.g., “all parameter changes by User X between Date Y–Z”). Data export supports CSV, PDF, and XML formats compatible with LIMS platforms (LabWare, Thermo Fisher SampleManager). Remote access via TLS 1.2–secured HTTPS tunnel enables off-site validation oversight and real-time deviation review without local network exposure. Software validation documentation includes URS, FRS, IQ/OQ test scripts, and performance qualification reports—all supplied as editable Word/PDF deliverables.

Applications

• ICH Q1A(R2) long-term, accelerated, and stress testing of small-molecule APIs and finished dosage forms
• ICH Q5C photostability pre-conditioning (dark storage phase) prior to ICH Q1B irradiation cycles
• USP excipient compatibility screening under controlled humidity gradients
• cGMP batch release stability hold conditions for sterile injectables and large-volume parenterals (LVPs)
• Regulatory submission dossier preparation per FDA eCTD Module 3.2.P.8 and EMA CTD Section 3.2.P.8.3
• Climate zone III/IV mapping studies per WHO TRS 992 Annex 9

FAQ

Does the SHH-3000SD-2T meet FDA 21 CFR Part 11 requirements for electronic records and signatures?

Yes—the system includes built-in electronic signature workflows, audit trail generation, and data integrity controls fully aligned with Part 11 Subpart B criteria.
Can the unit operate reliably at 40 °C and 20 % RH for lyophilized product studies?

Yes—its dedicated desiccant-assisted dehumidification module achieves stable 20 % RH at 40 °C with ≤±1.8 % RH drift over 72-hour validation runs.
Is third-party calibration and certification available?

YSEI provides optional NIST-traceable calibration services through ISO/IEC 17025-accredited partners, including on-site sensor verification and uncertainty budget reporting.
What is the expected mean time between failures (MTBF) for critical subsystems?

Based on field data from >120 installed units, the refrigeration system MTBF exceeds 18,000 hours; humidity control module MTBF exceeds 12,500 hours.
How is cybersecurity addressed for remote monitoring functionality?

All remote connections require mutual TLS authentication; no default credentials are shipped; firmware updates are cryptographically signed and verified prior to installation.
