The condition of stability room where the stability samples are stored is controlled at 30±2℃ and 75±5%. Per the mapping study, the cold spot, hot spot, minimum humidity, maximum humidity are at No.7, 14, 1, and 2 respectively. However the sensor for humidity and temperature is only placed at the hot spot No.14. Discussed this with Biolab staff and they agreed to discuss with their ENG and install a sensor at cold, min, maximum humidity spot as well to make sure the temperature drop below 28 degrees c can be monitored.
