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 cheek to see what kind of bacteria is in your mouth, study the bacteria that lives in soil or pondwater, and try growing photosynthetic bacteria.
