You can use a microwave as an autoclave if you use the very old
protocol called "tyndallization". Robert Tyndall, back in the
1870's, found that heating once to boiling did not kill the
endospores left behind by some bacteria. But, heating and cooling
sealed vesseled repeatedly over several days does eventually
kill all the microbes. I know this is impractical in most labs,
but it does allow you to use the microwave for sterilization.
You may want to look into it.
