Description
A microbiological media “plate” that consists of 2 clear plastic film sheets with sterile medium in between. This super-thin layer of medium supports the growth of microorganisms just like the surface of an agar plate. A class set stacks in the same space as one petri dish. Petrifilm™ plates can be counted on a standard colony counter or other magnified light source. Store unopened Petrifilm™ plate pouches at a temperature of 8° C.
