YSEI SHH-2000SD-2TD Dual-Door Pharmaceutical Stability Testing Chamber

Overview

The YSEI SHH-2000SD-2TD Dual-Door Pharmaceutical Stability Testing Chamber is an ICH-compliant environmental simulation system engineered for long-term, accelerated, and intermediate stability studies of pharmaceutical products in accordance with ICH Q1A(R3), Q1B, Q5C, and related regulatory frameworks. It operates on a precision-controlled dual-loop thermohygrometric principle—employing independent PID-regulated refrigeration, heating, and humidification subsystems—to maintain stable, traceable, and reproducible temperature (±0.5 °C) and relative humidity (±3% RH) profiles across extended durations. Designed specifically for compliance-critical GMP environments, the chamber supports mandated test conditions including 25 °C/60% RH (long-term), 40 °C/75% RH (accelerated), and critically, low-humidity protocols such as 40 °C/25% RH required for large-volume parenterals and hygroscopic APIs. Its structural architecture adheres to GB/T 10586–2025 (Environmental Test Equipment – General Technical Conditions) and metrological validation requirements per JJF 1101–2019 (Calibration Specification for Temperature and Humidity Parameters of Environmental Test Equipment).

Key Features

• Dual-door configuration: Outer door with electromagnetic lock and mechanical key access control; inner tempered glass door for non-intrusive visual monitoring—minimizing thermal/hygrometric disturbance during observation.
• Redundant safety architecture: Independent overtemperature protection in working chamber; dry-run protection for humidifier; compressor overload safeguard; power-failure detection with auto-restart and data continuity.
• Integrated SMS alert system: Configurable threshold-based notifications for temperature/humidity deviation, power interruption, door breach, or system fault—supporting centralized management of up to 30 units via single SIM gateway.
• Energy-optimized operation: High-efficiency scroll compressor, vacuum-insulated panel construction (≥120 mm thickness), and adaptive duty-cycle control reduce average power consumption by ≥22% versus conventional chambers under 40 °C/75% RH load.
• Acoustic engineering: Noise emission <52 dB(A) at 1 m distance—validated per ISO 3744—enabling installation in shared laboratory corridors without acoustic isolation.

Sample Compatibility & Compliance

The SHH-2000SD-2TD accommodates standard ICH-compliant sample racks (up to 2000 L internal volume), supporting vials, blister packs, ampoules, IV bags, and lyophilized formulations. Its chamber geometry and airflow design ensure uniformity per ICH Q5C Annex 1 (±0.8 °C spatial uniformity at 25 °C; ±2.5% RH at 60% RH). The system is pre-qualified for IQ/OQ documentation packages aligned with FDA 21 CFR Part 11, EU Annex 11, and WHO TRS 986 Annex 6 requirements. All calibration certificates are NIST-traceable; humidity sensors are polymer capacitive type with annual drift <0.8% RH. Validation support includes protocol templates, executed reports, and audit-ready electronic records.

Software & Data Management

Embedded 7-inch resistive touchscreen controller features 64 MB internal circular buffer and removable industrial-grade SD card (Class 10, 32 GB included). Data logging interval is user-configurable from 1 min to 24 h; at 15-min intervals, >3 years of timestamped records (setpoint, actual T/RH, alarm status, door events) are retained with power-loss resilience. USB 2.0 and RS485 interfaces enable local export and network integration. Optional YSEI SimsConnect™ software provides centralized multi-chamber supervision, real-time trend visualization, automated PDF report generation, and 21 CFR Part 11-compliant electronic signatures, audit trails, and role-based access control. Data files comply with ASTM E2500-13 (Standard Guide for Specification, Design, and Verification of Pharmaceutical and Biopharmaceutical Manufacturing Systems).

Applications

• ICH Q1-series stability protocols: Long-term (25 °C/60% RH), accelerated (40 °C/75% RH), intermediate (30 °C/65% RH), and stress testing (e.g., 40 °C/25% RH for moisture-sensitive biologics).
• Photostability assessment when integrated with optional ICH Q1B-compliant UV/visible light modules.
• Excipient compatibility screening under controlled humidity gradients.
• Reference standard storage under GMP-mandated ambient conditions (20–25 °C, 30–65% RH).
• Method transfer verification between R&D and QC stability labs.

FAQ

Does the SHH-2000SD-2TD meet FDA 21 CFR Part 11 requirements for electronic records?
Yes—the embedded controller and SimsConnect™ software provide full Part 11 functionality including electronic signatures, audit trails, data integrity controls, and secure user authentication.
Can the chamber maintain 40 °C/25% RH continuously for 6 months?
Yes—its dedicated low-RH dehumidification mode uses reheating + desiccant-assisted condensation, validated for sustained operation at 25% RH ±2.5% RH at 40 °C.
Is IQ/OQ documentation provided with the system?
Yes—YSEI supplies complete, editable IQ/OQ protocols and execution templates compliant with ISO 13485 and EU GMP Annex 15; on-site qualification support is available.
What is the maximum allowable ambient temperature for installation?
The unit requires ambient conditions of 5–35 °C and ≤85% RH; cooling capacity derates above 32 °C ambient—installation in air-conditioned labs is recommended.
How is data integrity ensured during power failure?
All logged data reside on non-volatile flash memory and SD card; controller retains time-of-failure stamp and resumes logging within 2.3 seconds post-recovery—zero data loss observed in 98.7% of 10,000+ simulated outage tests.
