9 Questions
Define sterilization and explain its purpose.
Sterilization is a process that effectively kills or eliminates transmissible agents from a surface, equipment, foods, medications, or biological culture medium. It is used to prevent contamination and achieve aseptic conditions.
What is the benefit of using dry heat for sterilization?
Dry heat has good penetrability and non-corrosive nature, making it applicable for sterilizing glassware and metallic instruments. It also destroys bacterial endotoxins that are difficult to eliminate by other means.
How does dry heat sterilization work?
Under dry heat, oxidative changes take place, and higher heat input is required. These changes destroy microorganisms and achieve sterilization.
What is the purpose of aseptic technique?
Aseptic technique is used when working with microorganisms to prevent contamination. It creates a sterile environment and ensures that no transmissible agents are present.
What are the types of physical agents used for sterilization?
The types of physical agents used for sterilization include dry heat, moist heat, and UV radiation.
What are the advantages of using dry heat for sterilization?
The advantages of using dry heat for sterilization include good penetrability, non-corrosive nature, destruction of bacterial endotoxins, and applicability to thermostable products.
What is the temperature range for dry heat sterilization?
Dry heat sterilization is typically done at a temperature range of 160-180 °C.
What types of materials are suitable for dry heat sterilization?
Dry heat sterilization is suitable for thermostable products and moisture-sensitive materials.
What happens to bacteria under dry heat sterilization?
Under dry heat sterilization, oxidative changes take place that destroy bacteria.
Test your knowledge on sterilization using physical agents such as dry heat, moist heat, and UV, as well as the importance of aseptic technique in preventing contamination. Learn about the various methods of sterilization and their effectiveness in eliminating microorganisms.
