The functions and performance characteristics of the drug stability test chamber

The drug stability test chamber is a device used to simulate specific environmental conditions and test the quality changes of drugs during storage and transportation. Its core function is to determine the validity period of drugs and the key factors affecting their stability (such as temperature and humidity). The ST301 drug stability test chamber is mainly applied in the pharmaceutical industry. By precisely controlling parameters such as temperature and humidity, it provides reliable data support for drug stability research.

The core advantages of the ST301 drug stability test chamber lie in its stable and reliable test results, precise temperature and humidity control, and long service life. It can meet the long-term, accelerated and intermediate stability test requirements stipulated in multiple standards such as the Chinese Pharmacopoeia, FDA, and ICH. At the same time, it can complete the low-humidity test of special drugs such as intravenous infusion at 40℃ and 20%RH. Its performance features are reflected in multiple aspects: Firstly, the temperature and humidity control is precise, with a temperature range of 0-65℃, fluctuation ±0.5℃, and uniformity ±1.0℃. The humidity range is 20-90%RH, with uniformity of ±3.0%RH. It adopts a balanced temperature and humidity control method and displays parameters in real time through a 7-inch color touch screen. Second, it has a complete safety protection system, equipped with dual anti-dry burning protection and an independent over-temperature protection system, which can automatically cut off power. At the same time, it is equipped with multiple safety devices such as compressor overheating, overpressure, and fan overheating. Third, the data management is standardized, supporting the setting of three levels of permissions (operator, administrator, and superuser), capable of storing electronic data for more than five years, and can output device information and temperature and humidity data through dot matrix printers. It can also be connected to an external PC for data storage and management. Fourth, the structural design is reasonable. The inner tank is made of 304 mirror-finish stainless steel, and the outer shell is made of high-quality steel plate with spraying. The double-door structure includes a tempered glass observation door and a fully enclosed outer door, which can block external light interference. The internal effective volume is 250L (customization available), and the external dimensions are 740, 850, and 1680mm. It is compatible with an AC 220V±10% 50Hz power supply with a power of 850W.
