3.0 Responsibilities:

  • Quality Assurance Manager: Overall responsibility for ensuring compliance with this SOP.
  • Laboratory Technicians: Responsible for the daily operation and monitoring of stability chambers.
  • Facility Manager: Responsible for the maintenance and calibration of stability chambers.

4.0 Equipment:

  • Stability chambers (with temperature and humidity control)
  • Data logging system
  • Calibration equipment
  • Temperature and humidity sensors

5.0 Procedure:

5.1 Chamber Setup:

  • Ensure the stability chamber is clean and free from any residues before starting.
  • Verify that the chamber is calibrated and operating within specified temperature and humidity ranges.
  • Place temperature and humidity sensors at appropriate locations within the chamber.

5.2 Sample Preparation:

  • Prepare samples according to the established protocols.
  • Label each sample with a unique identifier, including the date of placement into the stability chamber.

5.3 Chamber Operation:

  • Load samples into the stability chamber according to the established storage conditions.
  • Record the start date and time of the stability study.
  • Close the chamber door securely to prevent temperature and humidity fluctuations.
