How to prolong the service life of the drug stability test chamber?

As an important experimental equipment, the drug stability test chamber plays a vital role in ensuring drug quality and evaluating drug shelf life. In order to ensure its long-term stable and accurate operation, it is necessary to pay attention to its scientific and standardized maintenance. The following is a detailed description of the maintenance methods of the drug stability test chamber.

Daily cleaning and maintenance
- Appearance cleaning: Regularly wipe the outer shell of the test chamber with a clean soft cloth to remove dust, stains, etc. on the surface. Avoid using detergents containing corrosive ingredients to avoid damaging the surface coating of the box. For stubborn stains, you can soak a soft cloth with warm water and wipe it gently, but be careful to prevent moisture from entering the box.
- Internal cleaning: After each test, the residual samples and debris inside the test chamber should be cleaned in time. A vacuum cleaner or a soft brush can be used to remove dust from corners and gaps. At the same time, check and clean vents, radiators and other parts to ensure smooth air circulation.
- Glass door cleaning: If the test chamber is equipped with a glass door, it should be wiped regularly with a special glass cleaner to maintain its transparency and facilitate observation of the situation inside the chamber. When wiping, pay attention to moderate force to avoid scratching the glass surface.
Temperature and humidity control and calibration
- Temperature control: Regularly check the accuracy and sensitivity of the temperature sensor to ensure that it can accurately reflect the actual temperature in the box. It can be calibrated by comparing the standard thermometer with the temperature displayed by the test chamber. If the temperature deviation is large, you should contact professionals in time for adjustment or repair. At the same time, avoid drastic changes in the ambient temperature of the test chamber, which will affect its temperature control effect.
- Humidity control: For test chambers with humidity adjustment function, the performance of the humidity sensor should be checked regularly and calibrated. The water tank in the humidifier should be kept clean and the water source should be changed regularly to prevent bacteria from growing and impurities from clogging the nozzle. In addition, attention should be paid to the uniformity of humidity distribution in the test chamber. If there is unevenness, it can be improved by adjusting the position of the ventilation system or humidifier.
Electrical system inspection
- Power supply inspection: Regularly check whether the power cord of the test chamber is damaged or aged to ensure safe use of electricity. At the same time, check whether the power socket is firm to avoid equipment failure or fire hazards due to poor contact.
- Control system inspection: Regularly inspect the control system of the test chamber to check whether the display screen is displaying normally and whether the operation buttons are sensitive and effective. Check whether the software of the control system needs to be updated to ensure the stability and accuracy of its functions. If any abnormality is found, contact the manufacturer's technicians for repair in time.
Mechanical parts maintenance
- Compressor maintenance: The compressor is one of the core components of the test chamber, and its operating status, including sound, vibration, temperature, etc., should be checked regularly. Lubricating oil should be added according to the requirements of the instructions to ensure the normal operation of the compressor. At the same time, dust and debris around the compressor should be cleaned regularly to improve heat dissipation efficiency.
- Fan maintenance: The normal operation of the fan is essential for air circulation in the chamber. Regularly check whether the fan blades are deformed, worn, etc., and replace damaged blades in time. At the same time, clean the dust and dirt on the fan to ensure that its air volume is sufficient.
The maintenance work of the drug stability test chamber needs to be carried out meticulously and comprehensively. Only in this way can the performance of the test chamber be guaranteed to be stable and reliable data support can be provided for drug research and development, production and quality control.
