R-2A Broth Double Strength is used for cultivation and maintenance of heterotrophic bacteria from potable water.
Many bacteria from natural waters, which contain limited nutrients at ambient temperature, grow best on the media with less nutrient levels. They grow better at the temperatures below the routine laboratory incubation temperatures of 35°C-37°C. R-2A Broth enables better recovery of these bacteria from treated waters under different incubation conditions.
