YSEI SHH-100HWD-2 Drug Stability Testing Chamber

Overview

The YSEI SHH-100HWD-2 Drug Stability Testing Chamber is an engineered environmental simulation system designed specifically for long-term and accelerated stability studies of pharmaceutical products in accordance with ICH Q1A(R3), Q5C, and regional pharmacopoeial requirements (USP , Chinese Pharmacopoeia 2020 Vol. IV, Chapter 9001). It operates on a precision-controlled forced-air convection principle, utilizing dual PID-regulated heating and refrigeration circuits to maintain highly uniform temperature profiles across the entire 100 L working chamber. Unlike generic incubators or ovens, the SHH-100HWD-2 integrates pharmaceutical-grade validation readiness, dual redundant data recording, and remote operational integrity—ensuring compliance with Good Manufacturing Practice (GMP), Good Laboratory Practice (GLP), and regulatory audit expectations from initial qualification through routine use.

Key Features

• Precision thermal control architecture: Independent hardware-based over-temperature safety cutoff (separate from main controller) ensures fail-safe protection during high-temperature stress testing (e.g., 40°C/75% RH, 60°C dry heat).
• Dual-mode data recording: Built-in micro-thermal printer supports configurable print intervals (1 min to 24 h) for immediate hard-copy traceability; simultaneously, real-time sensor data (temperature, runtime, alarm status) streams to PC via RS-485 or Ethernet for secure archival.
• Scalable remote management: Up to 30 units can be daisy-chained and monitored from a single instance of YSEI StabilitySuite™ software using standard TCP/IP networks—enabling centralized oversight across multiple labs or sites without proprietary gateways.
• Energy-optimized design: High-efficiency compressors, low-power fan motors, and vacuum-insulated chamber walls reduce power draw to ≤1.2 kW at 60°C steady state—meeting ISO 50001-aligned energy performance benchmarks for lab-scale stability equipment.
• Pharma-ready validation support: Delivered with IQ/OQ protocol templates compliant with ASTM E2500-13 and Annex 15 (EU GMP), including pre-executed test scripts, calibration certificates (NIST-traceable Pt100 sensors), and 21 CFR Part 11-compliant electronic signature and audit trail configuration options.

Sample Compatibility & Compliance

The SHH-100HWD-2 accommodates standard stability storage configurations—including open trays, sealed aluminum foil-wrapped vials, blister-packed tablets, and primary packaging in ambient or controlled-humidity variants (when paired with optional humidity module). Its chamber geometry and airflow pattern have been validated per ICH Q5C guidance to ensure minimal thermal gradients (<±0.5°C at 60°C) and consistent exposure across all sample positions. All firmware, logging logic, and user-access controls conform to data integrity principles outlined in WHO TRS 996 Annex 5 and FDA Data Integrity Guidance (2018), supporting full ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) compliance.

Software & Data Management

YSEI StabilitySuite™ is a Windows-based application certified for use under 21 CFR Part 11 environments. It provides role-based user accounts, electronic signatures with biometric or token-based authentication, and immutable audit trails tracking every parameter change, data export, or report generation event. Raw time-series data are stored in encrypted SQLite databases with SHA-256 hashing; export formats include CSV (for LIMS integration), PDF (signed reports), and XML (for regulatory submission packages). The software also supports automated email/SMS alerts upon deviation events (e.g., temperature excursion >±1.0°C for >2 min), ensuring rapid CAPA initiation.

Applications

• ICH Q1A(R3) accelerated stability testing (e.g., 40°C/75% RH, 60°C dry heat)
• Long-term storage condition simulation (25°C/60% RH, 30°C/65% RH)
• Photostability pre-screening (when used with optional UV-filtered lighting kit)
• Excipient compatibility studies under thermal stress
• Package integrity evaluation during temperature cycling
• Reference standard storage verification per USP

FAQ

Does the SHH-100HWD-2 meet FDA 21 CFR Part 11 requirements for electronic records?
Yes—when configured with StabilitySuite™ in “Part 11 Mode”, it enforces electronic signatures, audit trails, and system access controls as defined in Subpart B. Full validation documentation (IQ/OQ/PQ) is available upon request.
Can this chamber operate continuously at 60°C for extended periods (e.g., 6 months)?
Yes—the unit is rated for uninterrupted operation at 60°C with verified thermal stability (±0.3°C control accuracy) and compressor thermal management optimized for sustained high-temperature duty cycles.
Is humidity control included in the base model?
No—humidity functionality requires the optional SHH-HUM-2 module (range: 20–80% RH, ±3% RH accuracy), which integrates seamlessly with the main controller and StabilitySuite™.
What validation support is provided beyond IQ/OQ templates?
YSEI offers on-site OQ execution services, NIST-traceable calibration certificates for all sensors, and PQ protocol development support aligned with your internal SOPs and regulatory filing strategy.
How is cybersecurity addressed for remote monitoring over corporate networks?
The embedded Ethernet interface supports TLS 1.2 encryption, configurable firewall rules, and segregated VLAN deployment. No cloud dependency or external telemetry is enabled by default—remote access remains fully on-premise controllable.
