2、 Application scenarios in the pharmaceutical industry: Quality control throughout the entire lifecycle

Drug development and stability research

Accelerated test: under high temperature and high humidity conditions (such as40℃±2℃The75%RH±5%RH）Simulate the long-term storage environment of drugs and predict their expiration date. For example, a biopharmaceutical company verifies the degradation rate of an anti-cancer drug under extreme conditions through a test chamber, and predicts the expiration date period from3Year shortened to6A month.

Influencing factor experiment: By controlling the temperature (such as-20℃to60℃）Humidity (such as20%RHto95%RH）Evaluate the impact of packaging materials on drug stability and optimize packaging design based on lighting conditions.

Production process validation

Freeze drying process optimization: in-50℃to80℃Simulate the freeze-drying process within a wide temperature range and verify the water removal efficiency during the sublimation stage by combining humidity control to ensure the uniformity and stability of the freeze-dried formulation.

Sterilization process validation: Through high temperature and high humidity (such as121℃The100%RH）Simulate wet heat sterilization conditions, verify the uniformity of temperature distribution inside the sterilization cabinet, and ensure the safety of sterile preparations.

Verification of storage and transportation conditions

Cold chain transportation simulation: in2℃to8℃Under low temperature conditions, combined with humidity fluctuation testing, evaluate the stability of drugs during transportation and reduce quality risks caused by temperature and humidity control.

Long term storage test: under constant temperature and humidity conditions (such as25℃±2℃The60%RH±5%RH）Continuously monitor changes in the physicochemical properties of drugs and provide data support for drug storage conditions.

3、 Typical case: Technology empowers industry upgrading
