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 1 petri dish! Petrifilm™ plates can be counted on a standard colony counter or other magnified light source.
Note: Store unopened Petrifilm™ plate pouches at a temperature of 8° C (46° F). Return unsued plates to pouch and store resealed pouches in a cool, dry place for no longer than 1 month. Expiration dates and lot numbers are noted on each package of Petrifilm™ plates.
