Study Notes
Sterile Product Preparation
- A carefully trained pharmacist or technician with proper training in aseptic technique and sterile product information is necessary.
Factors Affecting Adsorption
- The amount of adsorption depends on several factors, including:
- Concentration
- Surface area of the tubing
Sealed Ampoules Testing
- Sealed ampoules by fusion should be tested to ensure that a hermetic seal was obtained.
- The testing process involves:
- Immersing ampoules in a dye solution with their necks down in a vacuum desiccator.
Anatomy of the Eye
- The choroid is the second layer of the eye, located between the sclera and the retina.
- The choroid contains the blood vessels that provide nourishment to the outer layers of the retina.
Factors Influencing pH
- pH is influenced by several factors, including:
- Product degradation
- Diffusion of gases through the closure
- Effect of gases in the product
- Container and stopper effects
pH Buffering Agents
- Weak base and salt of a weak base or weak acid and salt of a weak acid are normally used as pH buffering agents, such as:
- Acetates
- Citrates
- Phosphates
This quiz tests your understanding of the process of ensuring hermetic seals in sealed ampoules by fusion. It involves immersing ampoules in a dye solution in a vacuum desiccator to check for any leakage.
