Petrifilm plates are premade, sterile Petri dish replacements that are ready for inoculation right out of their package. Students simply inoculate, incubate and count their molds. They will be surprised to learn that molds are everywhere! In addition, students will learn that molds come in many sizes, shapes and colors; vary in number from place to place; and are often difficult to control.
