CompactDry EC Plates - product information sheet
The usage of our Compact Dry EC Plates is a simple and safe way for the determination and quantification of E.coli and other coliform bacteria in water. Especially for settings with relatively poor infrastructure. The plates consist of a special 50 mm diameter petri dish containing a detection specific dry nutrient pad for E. coli and other coliforms. The medium contains two kinds of chromogenic enzyme substrates: Magenta-Gal and X-Gluc. Due to these substrates E.coli forms blue to blue purple colonies while coliforms show a reddish, red violet or pink coloration. The total coliform group count is the sum of all colonies identified as coliforms or E.coli.
