Working Principle of Desiccator in Pharmaceutical Laboratory:

The desiccator in a pharmaceutical laboratory operates on the principle of creating a low-humidity environment using a desiccant to ensure the preservation of sample integrity. The working steps involve moisture absorption, maintaining a dry atmosphere, and protecting pharmaceutical samples.

  • Desiccant Absorption:
    • Desiccant material (e.g., silica gel, calcium chloride) inside the desiccator absorbs moisture from the air.
  • Low Humidity Environment:
    • As the desiccant absorbs moisture, the humidity inside the desiccator decreases, creating a controlled and low-humidity environment.
  • Sample Placement:
    • Pharmaceutical samples, which are sensitive to moisture, are placed inside the desiccator to shield them from environmental humidity.
  • Sample Protection:
    • The low-humidity environment prevents moisture-induced reactions, preserving the stability and quality of pharmaceutical samples.
