Disposable Plasticware Such as Petri Dishes Can Be Sterilized Using

Question

Disposable plasticware such as petri dishes can be sterilized using which of the following?
A) ethylene oxide gas
B) steam autoclave
C) low-temperature, long-time pasteurization
D) phenol
E) 70% ethanol

Accepted Answer

Disposable plasticware, such as petri dishes, cannot withstand high heat and pressure required for steam autoclaving. Low-temperature, long-time pasteurization and phenol are not effective sterilization methods for plasticware. While 70% ethanol can sanitize plasticware, it is not a reliable sterilization method. Ethylene oxide gas is the most effective option for sterilizing disposable plasticware.
