I bought a sleeve from everything mushrooms. When I got it the package had a leak making them all unsterile, now waiting for a replacement. Is it a good idea to just spend more for Pressure cookable ones instead of disposable plastic ones? Seems like after all the transport you couldn't really rely on them being sterile to me..

they should be in a sterile packed plastic bag..as long as that bag hasn't been torn/ripped etc.. they're clean.

Really depends on a lot of factors.
I have some glass petri dishes, but I switched to PF jars for agar.

Really? How does that work you just pour a thin layer over the bottom and put the lid on? Actually sounds better than petri dishes....

Yep. The jars have a curved bottom, the center is shallower than the edge.
Better in some ways, but only on a small scale. But two or three dozen jars is a manageable amount.

Widemouth jar is wide enough to put in three samples, although there's no dividers you do get the space.

It costs more to clean and re-sterilize glass petri dishes than the disposable, pre-sterilized ones cost.

I give my old ones to the local school for science projects that don't require sterile dishes.
