Medium reagent Dry CF

for microbiologyfor coliformschromogenic

READY AND EASY TO USE PORTABLE PLATE: PREPARATION OF MEDIUM IS NOT REQUIRED, WHICH ELIMINATES WASTE OF MEDIUM AS WELL AS STERILIZING APPARATUS TO PREPARE THE MEDIUM. DETECTION OF COLONIES ON PLATE IS SIMPLE AND CLEAR. SINGLE COLONIES ON THE PLATE CAN BE ISOLATED FOR FURTHER IDENTIFICATION TESTS DESCRIPTION Compact Dry CF is an easy tool for the detection of coliforms. Coliforms grow with blue/blue green colonies as the recipe contains the chromogenic enzyme substrate X-GAL. The growth of bacteria other than coliforms is mainly inhibited but in case of growth they form colorless colonies. Compact Dry CF is AOAC, MicroVal und NordVal approved.
