Seran wrap instead of parafilm?

Hey guys. I just ran out of parafilm recently and was wondering if it would be okay to seal petri dishes with seran wrap?

you can use cling wrap, its ok.....You have to cut a strip out of the roll though. I think the best alternative to parafilm is regular old blue masking tape. Just buy the thinnest stuff they have and tape it up!

I've tried them all, and quite frankly there's no substitute for parafilm. Order some more. In addition to parafilm, I slip each dish into a ziploc bag, which I inflate before closing with air from my laminar flow hood. If you don't have parafilm, you could probably just put the dishes in ziploc bags, but only if you have a flowhood to inflate the bags with. RR

That is actually a pretty damn good idea! Can't believe I didn't think of it :-p. I do have a flowhood. I think i'm going to try that and maybe some micropore tape. Thanks. I've been using regular seran wrap, but I haven't been getting any growth at all on some plates.

dont even bother with micropore tape to seal petris. First, it leaves a horrible sticky residue and its hard to remove. Second, you mine as well use insect screening cause those pores arent all that micro. One day I will use a microscope to actually measure the nominal pore size in that stuff. Anyone got the equipment to do something like that?
