Unmodded 1/4 pints for agar? * 1
    #27286632 - 04/29/21 01:51 PM (3 years, 8 months ago)

Lately I've been seeing people using condiment cups for agar. I'd just do this but it's for poured agar, but I do no-pour just because I feel more confident in being sterile this way, and have always used just 1/4 pint mason jars. Is there anything I could do to at least minimize modifications to the mason jars so I could actually use them for food and whatever else when I want? I'm guessing just flipping the lid upside down before putting on the ring doesn't do enough for gas exchange if I don't already see people doing that right? Maybe use a disc of some synthetic filter paper for the lid instead, or flip the lid and put a narrow layer of micropore tape around the edge under the ring?

you could use a synthetic filter disk for the lid, as i'm pretty sure people do that for grains already. i'd recommend just getting plastic lids & leaving them slightly loose to allow for air exchange if you really didn't wanna modify the original lids. if you have a 2 piece metal lid i think the only way to provide safe gas exchange is gonna be to poke a hole in the top & cover it w micropore tape
