Overview
m-Endo Broth MF is the membrane filtration broth for total coliforms: an absorbent pad is saturated with the broth, the membrane placed on top, and after 22 to 24 hours at 35 °C coliforms appear as red colonies with a green metallic sheen. Used in APHA Standard Methods 9222B and US EPA drinking water methods, and convenient for field sampling. Contains dye and an ethanol preparation step; follow the directions and do not autoclave.
How selective media fit into the testing workflow
Pathogen testing normally runs in three stages: a pre-enrichment medium such as Buffered Peptone Water repairs injured cells and raises numbers, a selective enrichment then suppresses competing flora, and finally a selective differential agar isolates the target colonies. Selective agents are typically bile salts, dyes, or antibiotics; differential agents make target colonies develop a characteristic colour or morphology. Choose the combination specified by the method you follow.

Frequently asked questions
01Can selective media be autoclaved?
Not always. Some media containing dyes or selective inhibitors lose their selectivity if overheated and should only be heated until fully dissolved, without autoclaving. Follow the preparation instructions for this product, and contact us if you are unsure.
02How much powder per litre?
Use 48.05 g per litre of deionised water; preparation and sterilisation conditions are given on the specification sheet.
