Plastic petri dishes-not just for microbiology; use them for seed germination, storing beads or even as Jello dessert trays; only $7.95 for 20 dishes.

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.

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.
