Suying SY-100 Temperature and Humidity Controlled Stability Chamber

Overview

The Suying SY-100 Temperature and Humidity Controlled Stability Chamber is an engineered environmental test system designed specifically for long-term and accelerated stability studies in compliance with international pharmaceutical regulatory frameworks. It operates on a dual-loop PID-controlled refrigeration and humidification architecture, integrating precision air circulation, insulated double-wall construction, and calibrated sensor arrays to maintain stable thermal and hygroscopic conditions across the working volume. The chamber conforms to core requirements outlined in ICH Q1A(R2), ICH Q5C, and WHO Technical Report Series No. 953 (Annex 2), supporting mandated storage condition testing—including the long-term condition of 25 °C / 60% RH and the accelerated condition of 40 °C / 75% RH over six months. Its robust mechanical design ensures minimal thermal stratification and humidity gradient deviation, enabling reproducible data acquisition essential for regulatory submissions under FDA, EMA, and PMDA review pathways.

Key Features

• Microprocessor-based dual-channel PID control system with real-time digital display of setpoint, actual temperature, and relative humidity
• High-efficiency refrigeration unit with eco-friendly R134a refrigerant and independent humidity generation via steam humidifier with dehumidification via cooling coil
• Double-layer insulated stainless-steel inner chamber and cold-rolled steel outer shell with polyurethane foam insulation (≥100 mm thickness)
• Uniform airflow distribution via adjustable rear-mounted centrifugal fan and perforated top/bottom baffles to ensure ≤±1.5 °C temperature uniformity and ≤±3% RH uniformity per ICH-defined test zone criteria
• Over-temperature, over-humidity, compressor overload, and water shortage protection circuits with audible/visual alarm outputs
• Optional data logging module compliant with 21 CFR Part 11—supporting electronic signatures, audit trail, and user access level management

Sample Compatibility & Compliance

The SY-100 accommodates standard pharmaceutical packaging configurations including blister packs, HDPE bottles, glass vials, and secondary cartons. Internal dimensions (W×D×H) support up to 120 L usable volume, allowing placement of multiple ICH-specified sample trays with adequate spacing for convective exchange. All materials in contact with the test environment meet USP Class VI biocompatibility requirements. The system is validated per IQ/OQ/PQ protocols aligned with ISO 14644-1 (cleanroom classification), ASTM E2234 (environmental chamber performance verification), and EU GMP Annex 15. Calibration certificates traceable to NIM (National Institute of Metrology, China) are provided with each unit shipment.

Software & Data Management

An optional Windows-based stability monitoring software suite enables remote supervision, automated report generation (PDF/CSV), and trend analysis of temperature/humidity deviations over time. Data integrity safeguards include write-protection of historical records, timestamped event logs (door openings, power interruptions, alarm triggers), and encrypted database storage. The software supports configurable alert thresholds and email/SMS notifications for out-of-specification excursions. When configured for GLP or GMP environments, the system meets ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) and provides full 21 CFR Part 11 compliance documentation packages upon request.

Applications

• ICH-compliant long-term and accelerated stability testing of active pharmaceutical ingredients (APIs) and finished dosage forms
• Real-time shelf-life determination and expiration date assignment per regulatory guidance
• Excipient compatibility screening under controlled hygrothermal stress
• Biological product storage condition qualification (e.g., monoclonal antibodies, vaccines)
• Medical device packaging validation per ISO 11607-1 and ASTM F1980
• Environmental stress screening for electronics components and printed circuit boards (PCBs)

FAQ

What regulatory standards does the SY-100 support for pharmaceutical stability testing?
It fully supports ICH Q1A(R2), Q5C, WHO TRS 953 Annex 2, and USP <1151> environmental condition requirements.
Is the chamber suitable for GMP-compliant environments?
Yes—when equipped with the optional 21 CFR Part 11 software package and validated per Annex 15, it satisfies GMP data integrity and audit readiness requirements.
Can humidity be maintained at low temperatures (e.g., 10 °C)?
Yes—the integrated steam humidifier and condensation-controlled dehumidification system enables stable RH control across the full temperature range (10–100 °C).
What validation documentation is included?
Each unit ships with factory calibration reports, IQ/OQ templates, and a certificate of conformance to ISO 9001:2015 and GB/T 5170.2–2017 (Chinese national standard for temperature/humidity chamber verification).
