To determine the recommended temperature for the sterilization process in an autoclave, we need to evaluate each of the given temperature ranges and select the one that is universally recognized as effective for sterilization.
Here are the given temperature ranges:
1. 66° to 68° C (150° to 155° F)
2. 121° to 123° C (250° to 255° F)
3. 82 to 85° C (180° to 185° F)
4. 138° to 141° C (280° to 285° F)
Autoclaves are commonly used in medical and laboratory settings for sterilization purposes. The most effective and recommended temperature for sterilization is typically within the range of 121° to 123° C (250° to 255° F). This temperature is effective because it is high enough to ensure the destruction of all forms of microbial life, including spores, which are particularly resistant.
Given the choices:
1. 66° to 68° C (150° to 155° F) - This temperature range is too low and not sufficient for effective sterilization.
2. 121° to 123° C (250° to 255° F) - This temperature range is recommended and effective for sterilization.
3. 82 to 85° C (180° to 185° F) - This temperature range is also too low and not sufficient for effective sterilization.
4. 138° to 141° C (280° to 285° F) - While this temperature range is higher than the recommended range, it is not commonly used due to the risk of damaging certain materials and the practical difficulties in achieving and maintaining such high temperatures safely.
Therefore, the recommended temperature for effectively performing sterilization in an autoclave is:
121° to 123° C (250° to 255° F)
The recommended choice is:
