Half a petri dish
    #27113041 - 12/28/20 08:18 PM (3 years, 1 month ago)

Thought I'd put this out to the brains trust. I've ended up 150 glass petri dish bases e.g. no lids.

Anyone have any good ideas on how I could still use the bases for agar work? Any DIY hacks for lids?

Not sure how this is advanced but maybe use a bottom as a top and cling wrap/Parafilm it closed :shrug:

You should probably just get the tops tho

It won't work because there is almost no chance to make it sterile with any existing techniques (effort and tools).

Sterilize the agar and then sterilize the Petri dishes separately. Pour the sterilized agar into the sterilized dish in aseptic conditions. Cover with a sterilized bottom then wrap with cling wrap.

It’s definitely not ideal nor would I recommend even attempting it, just get the proper equipment, but the dude asked if there was a way

How clear are the bases? Are they clear enough that they could be used for lids?

If they can be used for lids to any degree I would use something else for a base.

I'm not sure of the dimensions of your bases so I don't know what would actually fit, but just as an example you could use your bases as lids for 1/4 pint jars, or you could mabey use some sort of heat resistant plastic dish as a base, like a yogurt container cut to size,or whatever you have or know of that might make a better fit

I am not sure if this will help you but there is a post I seen on here called
“homemade lids that have stood the test of time”

Try distributors that sell caps, clisures, containers, etc. In a quick search I came across a few cheap options for quantity orders. Additional bonus metal mason jar covers with center holes in loads of colors, even camo.
