quick agar q's
    #4171269 - 05/13/05 04:34 PM (12 years, 1 month ago)

faq secion on agar is really lagging.

anyway, can plastic, polystyrene petri's be reused? they say single use, but that doesnt always mean the truth.

also, i have some agar that's about 2 months old that i sterilized, in the fridge in a quart jar(and used in mason jars.) can i just re heat that, and then pour the dishes from that? or should i re sterilze it? or, would it be better to start off with new agar?

thanks.

if the polystyrene will hold up to pcing then go for it. as far as the agar, if there are no contams growing on it then go ahead and remelt and pour. i guess you could pc again if you are having any doubts, should be ok. good luck.

hard to say if they will hold up, we only use them one time and then toss them. try one out and see. i would imagine that they will be ok. if you use a bleach solution (200 ppm) to sanitize them make sure you rinse them several times (4 or 5 times) to be sure all the residue left behind is rinsed away. you could also try a dry heat sterilization in your oven around 340 degrees for not less than 2 hours.

afoaf reuses them by dipping in bleach then dipping into distilled water under a flow hood.
