YSEI SHH-1000SD-2TA Drug Stability Testing Chamber

Overview

The YSEI SHH-1000SD-2TA Drug Stability Testing Chamber is an ISO/ICH-compliant environmental simulation system engineered for pharmaceutical stability studies in accordance with ICH Q1A(R3), Q1B, Q5C, and relevant sections of USP , EP 2.2.47, and Chinese Pharmacopoeia (ChP) Volume IV. It implements precise, long-term control of temperature (±0.3 °C uniformity) and relative humidity (±2.0 % RH uniformity) across its 1000 L working volume, enabling conformance to long-term (25 °C/60 % RH), accelerated (40 °C/75 % RH), and intermediate (30 °C/65 % RH) test conditions per ICH guidelines. The chamber employs dual independent PID-controlled refrigeration and humidification subsystems, coupled with a high-efficiency air circulation architecture featuring laminar airflow distribution and low-turbulence recirculation—ensuring spatial homogeneity and temporal stability critical for regulatory-grade shelf-life determination and degradation pathway analysis.

Key Features

• Triple-layer insulated double-door structure: Outer door with dual mechanical locks + inner tempered glass observation door minimizes thermal/hygrometric disturbance during sample inspection.
• Comprehensive safety architecture: Independent overtemperature protection in chamber cavity; dry-run protection for humidifier reservoir; compressor overload and phase-failure monitoring; configurable SMS alerting for power failure, temperature excursion (>±2 °C), or humidity deviation (>±5 % RH).
• Regulatory-grade data integrity: Full audit trail compliant with FDA 21 CFR Part 11 and EU Annex 11 requirements—including user-level access control (three-tier permission hierarchy), immutable operation logs, tamper-evident timestamps, and electronic signature support.
• Redundant data recording: Internal 4GB flash memory with circular buffering; optional SD card export (FAT32 formatted); 1-minute interval logging capacity exceeding 10 years; battery-backed real-time clock ensures continuity during mains interruption.
• Energy-optimized design: EC fan motors, variable-speed refrigeration compressor, and intelligent dew-point-based humidification reduce average power consumption by up to 28% versus conventional chambers under 40 °C/75 % RH operation.
• Remote interoperability: Supports simultaneous connection of up to 30 units via Ethernet; compatible with YSEI Sims™ remote monitoring software for cross-site calibration validation, parameter adjustment, and alarm dispatching over secure HTTPS/TLS channels.

Sample Compatibility & Compliance

The SHH-1000SD-2TA accommodates standard pharmaceutical packaging formats—including blister packs, HDPE bottles, aluminum tubes, and secondary cartons—within its uniformly conditioned workspace. Its internal dimensions (D×W×H: 950 × 850 × 1250 mm) allow placement of multiple ICH-specified stability batches without compromising air exchange efficiency. All materials contacting the chamber interior meet USP Class VI biocompatibility criteria. Validation documentation—including IQ/OQ protocols aligned with ASTM E2500-13 and ISPE GAMP 5—is provided upon delivery. The system satisfies GMP Annex 15 requirements for computerized system validation and supports full lifecycle traceability from installation through routine performance qualification.

Software & Data Management

The embedded controller runs YSEI’s validated StabilitySuite™ firmware (v4.2+), supporting configurable data acquisition frequency (1–60 minutes), customizable alarm thresholds, and role-based UI navigation. Real-time data streaming to Windows-based PCs enables synchronized logging with third-party LIMS or ELN platforms via OPC UA or Modbus TCP. All electronic records are generated in CSV and PDF formats compliant with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available). Audit trail exports include operator ID, timestamp, parameter change value, pre-change state, and reason-for-change annotation fields.

Applications

• ICH-compliant long-term, accelerated, and stress testing of APIs and finished dosage forms (tablets, capsules, injectables, creams).
• Photostability assessment when integrated with optional ICH Q1B-compliant light cabinets (sold separately).
• Excipient compatibility screening under controlled hygrothermal stress.
• Stability-indicating method development support through parallel condition replication.
• Storage condition qualification for warehouse mapping and cold chain validation.
• Regulatory submission dossier preparation (e.g., CTD Module 3 stability data packages).

FAQ

Does the SHH-1000SD-2TA support 21 CFR Part 11 compliance out-of-the-box?

Yes—the system ships with pre-validated electronic signature workflows, audit trail encryption, and role-based access controls fully aligned with Part 11 technical and procedural requirements.
Can historical data be exported in machine-readable format for statistical analysis?

All logged data is natively exportable as time-stamped CSV files with column headers conforming to ASTM E2500-13 metadata conventions.
Is on-site IQ/OQ execution included in the standard warranty?

IQ/OQ protocol documents are supplied with delivery; on-site qualification services are available as a billable add-on, performed by YSEI-certified validation engineers.
What is the maximum ambient operating temperature range for reliable chamber performance?

The unit is rated for continuous operation in ambient environments between 5 °C and 35 °C at ≤85 % RH, as specified in GB/T 10586-2025.
How does the system handle power recovery after an outage?

Upon power restoration, the controller resumes operation from last-known setpoints with no configuration loss; buffered data remains intact due to non-volatile memory and supercapacitor backup.
