Stupid questions: Are plastic petris PCable?
    #2857517 - 07/05/04 01:42 AM (13 years, 5 months ago)

It's something I've been wondering about. I know that these kinds of plates are generally pre-sterilized via radiation, but I don't trust my sterile technique enough to be pouring plates without sterilizing them afterwards.

No. They are typically made of polystyrene which is not autoclavable...

Edit:
And pressure cooking previously poured glass plates isn't a good idea either. Usually the agar will boil over, leaving you with nothing but a big mess...

???

The petris are sterile in the sleeve -- if you sterilize them afterward won't you dry them out?

Regardless, they could be PC'ed, but will warp if you give it enough time at a that temp. I'm sure you could get away with it at the bare minimum, at least with some petris, but I have had them melt sitting in the trunk of my car....

They will melt completely.
