3M™ Petri?lm™ Aqua Coliform Count Plates are sample-ready media plates used to measure coliform levels in bottled water. 3M™ Petri?lm™ Aqua Coliform Count Plates deliver reliable testing results for your bottled water.
Each plate contains a water-soluble gelling agent, nutrients and indicators in a dry, shelf-stable format. The indicator dye colors all colonies red, and the top film traps the gas produced by the coliforms. Gas trapped around red coliform colonies indicates confirmed colonies.
