Plastic petri dishes-not just for microbiology; use them for seed germination, storing beads or even as Jello dessert trays; only $3.95 for 10 dishes.

Sterile plastic petri dishes for microbiology, seed germination, 85mm diameter lid, 70mm ID diameter base. Can even be used with magnets to view iron filings. Buy disposable plastic petri dishes for microbiology or plant culture.

We do not supply agar but you can buy it at baking goods stores. Or, you can use gelatin instead-see below for a simple recipe you can do at home.


Plastic petri dishes are by their nature, disposable. However, some types are extremely flimsy. Ours are 1.1-1.2mm thick & weigh ~16g each which can be as much as double as the cheaper ones.

You can easily prepare your own general culture media which should support common bacteria & molds using the following instructions: Homemade Microbial Media. Or, you can try some of these nutrient agar recipes.

Fantastic products!

— Jackson

My purchase, the packaging, and delivery were great. This was my first attempt with germinating "old" seeds in the dishes. I had productive results. The dishes were well worth the cost and investment of my time.

Planting seeds & discovering too late they aren't viable. Glad this is a useful solution to prevent that. 


Plates were sterile and well packaged. Shipment came within a week and was few dollars cheaper than Amazon even with shipping. Will definitely be back to buy more soon.

Excellent product and great price! I use them for lab work and I have never had any problem with them. 100% success rate. Totally sterile.

Happy with the service and merchandise (Petri dishes). Will re-order again. Cheers, Tom
Great quality, thicker plastic than anything on Amazon and never received broken cases nor punctured sleeves. Buying bulk elsewhere it is common for at least a couple sleeves to have manufacturing defects which renders them unusable. Will always be purchasing from Indigo Instruments.

Was initially concerned about quality because price was so low, but I am glad I tried Indigo Instruments. Product arrived pretty quick and was packed well and fully intact.
