  • Picture 1

The TTC/MAC dipslide allows convenient enumberation of aerobic microorganisms (TVC) as well as the cultivation Enterobacteriaceae (coliforms). The dipslide is prepared with nutrient TTC agar on one side and MacConkey No3 agar on the other (reddish/brown). The MacConkey No3 agar selects for bile tolerant gram negative bacteria found in waters and sewage. The additive in the nutrient agar reacts with enzymes produced in aerobic respiration to produce a colour change from white to red, allowing easy enumeration. Gram-positive bacteria will not grow on this media.

Dipslides have a working shelf life of 3-9 months.

Results are quantified by comparison to a standard density chart.

Dipslides are supplied in a cardboard carton containing 10 slides.
