Standards
WHO Principles Require:
Long-term stability testing conditions at 25°C/60% RH humidity.
The 40°C/75% RH humidity standard for 6-month accelerated testing is primarily applied in the pharmaceutical industry's stability testing systems, simulating environmental climate conditions including temperature, humidity, and light exposure.
Features
1.Modular Structural Integrity: The lab utilizes a unitized assembly design, allowing you to expand the internal volume or relocate the facility with minimal effort as your production scales.
2.Advanced Airflow Design: By employing a side-top air supply and side-bottom return principle, the system eliminates dead zones, ensuring that even a fully loaded room maintains exceptional temperature and humidity uniformity.
3.Precise Control Algorithms: You benefit from a micro-integral PID control system that coordinates cooling, heating, and humidification to prevent parameter overshoot and ensure rapid recovery after door openings.
4.Regulatory-Grade Monitoring: The high-sensitivity PT100 sensors and dual-mode (program/constant) operation allow you to meet the most stringent ICH stability protocols without manual intervention.
5. Safety Suite: The system includes multi-level protection against over-temperature, low water levels, compressor over-pressure, and phase-sequence anomalies, ensuring 24/7 unmanned operation safety.

Test Procedures
1.Startup and Monitoring:
Start the test chamber and monitor parameters such as temperature and humidity in real time to ensure they remain stable within the set range.
Record data regularly, such as sampling and testing at the end of the 1st, 2nd, 3rd, and 6th months for long-term tests.
2.Abnormal Condition Handling:
If parameters deviate from set values, immediately stop the test, inspect the equipment, and take corrective actions.
3.Recording Requirements:
Document test conditions, timestamps, and results in detail to ensure data integrity and accuracy.
4.Data Analysis:
Evaluate drug stability under varying conditions and assess degradation trends.
Prepare reports including test conditions, data, conclusions, and recommendations.
