The R2A medium was developed to assess the bacteria plate counts of treated potable waters and the detection of oligotrophic heterotrophs. R2A is a low nutrient agar which, in conjunction with a longer incubation period, has been show to give significantly higher colony counts. For ease of enumeration, 2,3,5-triphenyltetrazolium chloride (TTC) has been added which dyes colonies red. R2A Aga is recommended in Standard Methods for the Examination of Water and Wastewater for pour plates, spread plate and membrane filter methods for heterotrophic counts.

Dipslides are supplied in a cardboard carton containing 10 slides.
