A new generation of drug stability testing equipment, integrating the company's many years of design and production experience, introduces and digests German technology. It breaks through the defect that the existing domestic drug test chamber cannot run continuously for a long time. It is a necessary equipment for GMP certification of pharmaceutical factories. Product Usage: Use scientific methods to create a long-term stable temperature, humidity environment and light environment for drug failure evaluation. It is suitable for accelerated testing, long-term testing, high humidity testing and strong light exposure testing of drugs and new drugs by pharmaceutical companies. It is a pharmaceutical company The best option for drug stability testing. Features: ◆Humanized design ●Follow the world's environmental protection trend, brand new fluorine-free design, high efficiency, low energy consumption, and promote energy saving, so that you will always be at the forefront of healthy life. ●Microcomputer controller, the control is stable, accurate and reliable. It adopts 304 stainless steel liner, and the four corners are semi-circular arc shape, which is easy to clean and easy to operate. ●Unique air circulation to ensure uniform wind distribution inside the studio. There is a test hole with a diameter of 25mm on the left side of the box. ◆Continuous operation guarantee ●Two sets of imported compressors are automatically switched to ensure that the drug test runs continuously for a long time without failure. Break through the defect that the domestic drug test chamber cannot run continuously for a long time. ◆Quality Assurance ●Key components such as temperature and humidity controllers, compressors, and circulating fans are imported products, which have the characteristics of stable, safe and reliable operation for a long time. ◆Safety function ●The independent temperature limit alarm system can alert the operator with sound and light to ensure that the laboratory runs without accidents. Low temperature or deviation and over-temperature alarm. ◆Imported humidity sensor ●Choose a humidity sensor that can operate at a high temperature to avoid the trouble caused by frequent replacement of wet and dry bulbs. ◆UV sterilization system (optional) ●The ultraviolet germicidal lamp is placed on the back wall of the box, which can disinfect the inside of the box regularly, which can effectively kill the floating bacteria in the circulating air and water vapor of the humidifying pan in the box, thereby effectively preventing pollution during the drug test. ◆Automatic monitoring and control of illuminance (optional) ●Break through the defect that the illuminance cannot be monitored and controlled by the existing domestically made stable test chamber. The light sensor is used for monitoring and steplessly adjustable to reduce the attenuation of illuminance and test errors caused by the aging of the lamp tube. ◆Data record and fault diagnosis display ●When the test box fails, the dynamic display screen will show the fault information, and the operation failure of the test box is clear at a glance. It can be connected to a printer or 485 communication interface, and the temperature and time curve can be recorded by a computer and a printer, which provides a strong guarantee for the data storage and playback of the test process. Programmable touch screen controller (optional) ●Using a large touch screen, the screen operation is simple, and the program editing is easy. ●The operation interface of the controller is available in Chinese and English, and the real-time operation curve can be displayed on the screen. ●It has the capacity of 1000 sets of 999 cycle steps of 100 programs, and the maximum value of each period of time is 99 hours and 59 minutes. ●After data and test conditions are entered, the controller has a screen lock function to avoid shutdown due to human touch. ●With P.I.D automatic calculation function, the temperature and humidity change conditions can be corrected immediately, making the temperature and humidity control more accurate and stable. ●With RS-232 or RS-485 communication interface, you can design programs on the computer, monitor the test process and perform functions such as switching on and off. Fulfill the Standard: The 2015 edition of the Pharmacopoeia drug stability test guidelines and GB/T10586-2006 relevant provisions of the manufacturing ★Conditions of stability test: In the ICH guidelines, GMP and FDA define requirements in terms of functionality, performance and documentation. Europe, Japan, and the United States have agreed to develop a common stability test. The goal of these tests is to gather information as a recommendation on the stability of raw materials or drugs. The ultimate goal is to prove that the drug is exposed to temperature, humidity, Effectiveness in lighting or integrated environment. ★Storage conditions for stability test of long-term retained samples: Temperature: +25℃±2℃ Humidity: 60+5%RH Duration: 12 months ★Storage conditions for accelerated stability test Temperature: +40℃±2℃ Humidity: 75+5%RH Duration: 6 months Illumination under strong light conditions: 4500+500LX Technical Parameter: (Performance parameter test under no-load conditions: ambient temperature 20℃, ambient humidity 50%RH)
