R2A Liquid Medium

R2A Liquid Medium is a low-nutrient microbiological culture medium specially developed for the cultivation, recovery, and enumeration of heterotrophic bacteria in drinking water, purified water, bottled water, and environmental water testing. Designed to support stressed and slow-growing microorganisms, R2A Liquid Medium promotes superior bacterial recovery compared with conventional nutrient media used in water microbiology laboratories.

Its balanced formulation contains tryptone, acid hydrolyzed casein, yeast extract, glucose, soluble starch, and sodium pyruvate, providing essential nutrients, growth factors, and bacterial resuscitation support. Soluble starch helps neutralize inhibitory substances, while sodium pyruvate enhances the recovery of injured bacteria frequently found in water quality monitoring programs.

Widely used in drinking water testing, water microbiology analysis, environmental monitoring, heterotrophic plate count (HPC) applications, and microbial contamination detection, R2A Liquid Medium delivers reliable and reproducible results. Manufactured by Babio Biology, a leading Chinese manufacturer of microbiological culture media, this high-quality solution meets the needs of research laboratories, water treatment facilities, public health institutions, and quality control laboratories worldwide.
