설명

애플리케이션

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.

제조 메모

Suspend 51 g in 1 litre of distilled water containing 20 ml of ethanol 96 %. Boil to dissolve completely. Do not autoclave! Cool to 45-50°C and dispense 4 ml amounts into 50-60 mm Petri dishes and allow to solidify. The agar should be at least 1.5mm depth. Do not expose plates to direct sunlight.
