Petri dishes, plastic, 20/pk
Petri dishes are essential for bacteria science projects! Use them to grow bacteria cultures from around your house or live cultures like bacillus subtillis. This pack comes with 20 sterile disposable 90 x 16 mm plastic petri dishes & covers. They are ready to fill - just add agar. One 125 ml bottle of agar will fill about 10 petri dishes. (Just add enough to cover the bottom of the dish.) These plastic ones cannot be heat sterilized. They have been sterilized by deoxidation.
For some activities using petri dishes, check out our bacteria experiments. Other ideas: swab the inside of your check to see what kind of bacteria is in your mouth, study the bacteria that lives in soil or pondwater, and try growing photosynthetic bacteria.

They grow bacteria very well. - Friday, July 10, 2009 Great ProductReviewed By: Stephanie This is a great product for my 3rd, 4th, and 5th graders. We are studying bacteria, and had a blast finding the dirtiest places in the room. The dishes came well packed and protected. I will be back next year!  - Wednesday, April 01, 2009 PlasticReviewed By: Rachael Ranney I like these Petri Dishes. Unfortunately, these are plastic! I won't recommend these dishes for difficult higher level science classes, but for younger grades without much involvment these are great! - Wednesday, March 18, 2009 Perfect!

they worked great for what we needed them for but several were broken during shipping. possibly a smaller box or more packing material would have helped.

petri dishes
These are great, standard size for all experiments, easy to use, lids work great-they sit like all petri dish lids sit on top of them. I will order again & again as needed.

These are great. My husband and our kids collect all kinds of things in them to look at under the microscope.

We Love These
We used these petri dishes with the Magic School Bus Germs science kit. The lids fall off easily when in storage, so you have to keep them in a safe place so they will not be exposed to germs. We bought the Agar from homescience tools too and it works great with these petri dishes. The price is awesome. Thank you homesciencetools!

We use these dishes all the time to look at specimens under the microscope. No more using mom's tupperware to hold ants, spiders, etc!
