Application

m-Endo Agar LES can be used for the enumeration of coliforms in water using the Membrane filter technique for coliform enumeration. This method is more reliable and precise than MPN multiple test. It follows the two step membrane filter procedure using Lauryl Sulfate Broth (Cat. No. 17349) as a preliminary enrichment, resulting in higher coliform counts.

Footnote

The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.
