Where can I find good quality glass petri dishes
    #28672427 - 02/23/24 08:28 AM (10 months, 18 days ago)

I was looking on Amazon and most of the stuff seen where glass is thin or they break easy or the lids have extra space between the base plate.

Any input on good quality petri dishes that the lid and bottom fit snug would be great

I've also seen online about plastic petri dishes that says you can reuses and are autoclave safe, does anyone have any experience with those?  I would think that with being plastic that I would not be able to fully sterile due to bacteria can get in small places .

Have a read here to get an idea.
You want polypropylene, or just PP#5.
It can withstand pc temps.

If you find a good source for glass be sure to share. I hate one-time-use products, but nothing beats the ease of use of celtreat grip ring plastic petris. And so far, I am not sure that I will ever break even cost wise on the reusable glass versus disposables. Of course the math works out in theory, but with failure, breakage, and having enough on had for longer term storage or plins, it is a gonna take longer than it might first seem.

The cheap glass ones on amazon have I high failure rate e.g. I receive a percentage that are broken and find several more cracked but usable after the first sterilization.

I also have a set of pyrex that I bought when I first started out. They are far superior in every way, but you pay for it and they still break if mishandled (in shipping or the lab).

But right now I am working my way through trying some of the cheaper ones on the zon, because even with the failure rate of the cheap ones, I still get more usable plates for my money by a factor of 3 or more. 

I am about to splurge on some slightly more expensive cheapies to see if they make a difference or it is all advertising fluff. If they are better I will try to remember to come back and post my findings when I pull the trigger.

If you’re in or near a large city check with the local university, many have reuse programs and sell lab equipment for dirt cheap when Labs shut down or new inventory is purchased and old discarded. I go religiously when I get a heads up from folks or when school starts and ends. Ive gotten cases of over 100 glass dishes for less than 10$ at mine. Highly recommend to look if the option is available in or near your area. It’s never a guarantee but worth the effort if you get lucky.

Autoclavable

Don't go over 15psi and these are great. Wrap groups of ten in loose foil to PC. Make a foil cradle to keep them off the bottom. I've done the same 30 numerous times with zero issues.

They make me happy.

wish i would have read a bit more before pulling the trigger. my 100mm plates sit carefully packed away in their bubble wrap and paper between top/bottom. i broke one a few days ago. they make me worry.  they were $5/ea, bought direct from local lab supply.  they're great, but i feel like a fancy fool.

:imo: Buy taller 20mm+ glass petri when planning to used them for no-pour. They are more expensive than 15mm.
