In the pharmaceutical industry, temperature is crucial for drug production, storage and quality assurance. Dry-block calibrators play an indispensable role in temperature validation work in the pharmaceutical industry. The temperature accuracy of various process equipment in pharmaceutical production, such as reactors, sterilizers, freeze dryers, etc., needs to be strictly validated. Dry-block calibrators can simulate the working temperature range of these equipment and accurately calibrate and validate the temperature sensors installed on the equipment. In the drug storage stage, dry-block calibrators can be used to calibrate the temperature monitoring system in the warehouse to ensure that the temperature of the drug storage environment meets the specified requirements. Through the application of dry-block calibrators, pharmaceutical enterprises can effectively ensure that the temperature control in the drug production and storage process complies with relevant standards such as GMP (Good Manufacturing Practice), thereby ensuring the quality stability and effectiveness of drugs and providing safe and reliable drugs for patients.
