Used by biologists to culture bacteria and other microbes, these plastic petri dishes provide the perfect home for "growing" your latest science experiment.

• 20 Pack of Petri Dishes that are 51 mm (2") in diameter

How does it work?

Partially fill your petri dishes with a perfect mixture of nutrients that provide food for microbe growth. Scientists often use hot agar mixed with salts, amino acids and other substances perfect for supporting the particular microbes they wish to study. When the mixture cools, place your tiny cells on top of the surface and watch them multiply. Don’t worry, they take some time to grow!
