Soleris® Coliform Vial, 9 mL

The Coliform Vials are a screening vial specific for coliform or­ganisms. The vial has broad inclusiv­ity and an assay time of 14-24 hours for most applications. The vial contains a peptone yeast extract base with lac­tose as a carbon source. The selec­tive agents include bile salts, sodium lauryl sulfate and other gram-positive inhibitors. Acidification of the medium due to the lactose utilization changes the pH indicator from a purple to a yel­low color. The color change is read by optical sensors in the instrument.
