Question

q17. what is the minimum recommended temperature for steam sterilization in a dynamic - air - removal sterilizer? 121 c (250 f) 132 c (270 f) 134 °c (273°f) 140 c (284 f)

Explanation:

Steam sterilization in a dynamic - air - removal sterilizer (also known as a prevacuum autoclave) requires higher temperatures to ensure effective sterilization. The minimum recommended temperature for this type of sterilization is based on the need to destroy all microorganisms, including spores. A temperature of \(132^{\circ}C\) (\(270^{\circ}F\)) is sufficient to achieve this under the conditions of a dynamic - air - removal sterilizer. At \(121^{\circ}C\) (\(250^{\circ}F\)), which is the temperature for gravity - displacement autoclaves (not dynamic - air - removal), the sterilization process may not be as effective in the presence of air pockets that can remain in dynamic - air - removal sterilizer - like setups if the temperature is too low. Temperatures of \(134^{\circ}C\) (\(273^{\circ}F\)) and \(140^{\circ}C\) (\(284^{\circ}F\)) are higher than the minimum requirement.

Answer:

132 C (270 F)
