Perform coliform testing without the mess of making and sterilizing Petri dishes! This kit uses the revolutionary new Petrifilm™ culture plates. E. coli/Coliform Plates are ready for immediate use when you receive them. The paper-thin media film is not activated until you inoculate it with your test samples. The unique indicator dyes in the media make counting coliform colonies easy. The open-ended inquiry activity in this kit has students test items of their own design for coliform presence. Your students will be amazed to find out that water that looks clear may be harboring dangerous pathogens. Includes complete instructions for using Petrifilm Plates, activity suggestions, a package of 25 Petrifilm E. coli/Coliform Plates, Petrifilm spreaders and teacher demonstration materials.
The E. coli culture is available separately.
