Application

m-TEC ChromoSelect Agar is recommended by the U.S. Environmental Protection Agency (USEPA) for differentiation and enumeration of thermotolerant Escherichia coli from water by membrane filtration technique. m-TEC ChromoSelect Agar has been used for membrane filtration of samples from the rivers, lakes and wetlands for subsequent isolation and culturing of Escherichia coli.
