goddam Pyrex! 5 bucks a piece, you can use them multiple times, slippery when wet, heavy, makes you feel like a scientist, cry when you drop one...plastic ones are dirt cheap, light weight and disposable...

Ive had much success from using salsa jars as petri dishes. They wont boil over while in the PC like petri dishes do. You can also put a silicone injection port in if you like. I dont use anything for gas exchange as i dont store my plates for long.

Peracetic acid-based sterilizing and disinfecting solution provides high-level disinfection and is completely effective against spores. Ready-to-use solution is tuberculocidal, bactericidal, virucidal, and fungicidal. Completely biodegradable, it decomposes into oxygen, water, and acetic acid.
I know its used in the food industry.
I wouldn't use it to disinfect dishes before use. But I think it would be good to spray down the room and work surfaces.

I will also put dishes with agar in the pc I do not have aproblem with them boiling over though. Maybe that could be from over filling them or releasing the steam too fast. I do this because I only make a couple at a time.

I realize there are more then one way to skin a cat. I may have over reacted. But I was taught to use a flask or bottle for the agar and to pour the hot liquid into sterile dishes in front of a hood.

if you PC petri dishes with agar in it, it's important to wait for the pressure cooker to reach normal pressure before opening it, otherwise the dishes will boil over. i allways PC my petri dishes prefilled with agar, but for more than a decade i'm just working with glass dishes. they cost about $1.50 in Europe. started with a package of 10 - meanwhile over the years i'm working with hundrets of them. i try to avoid plastics where i can - have you ever thought about the ecological consequences of discarding hundrets of plastics petri dishes in a year or even a few month?! glass petri dishes can be cleaned and used over and over again. initial higher cost but on the long term it is cheaper for me to work with glass.
