The test tube contains sterile, dry enrichment material and pH colour indicator. For testing, the tube is filled up to 60-80 % of the capacity by the water sample, closed tightly, shaked up to dissolve the enrichment material, and let to stand at room temperature for 48 hours. During the 48-h cultivation period, any colour change from the initial dark purple towards orange or yellow indicates pH change due to coliform bacterial growth. If the colour change occurs, the water should not be used for drinking nor for household use.
