R2A Agar

R2A Agar - Advanced Medium for Bacterial Cultivation

Intended Use

R2A Agar is specifically designed for the enumeration and cultivation of bacteria from potable water, making it an essential tool in microbiological testing and water quality assessment.

Product Summary and Explanation

Developed by experts Reasoner and Geldreich, R2A Agar is renowned for its effectiveness in bacterial plate counts of treated potable water. This unique low nutrient medium is formulated to foster the growth of stressed and chlorine-tolerant bacteria, which are often overlooked in standard testing environments.

While typical nutritionally rich media may favour fast-growing bacteria, R2A Agar is particularly formulated to support the recovery of slow-growing or stressed populations. When evaluated against Tryptone Glucose Yeast Extract Agar or Standard Methods Agar, R2A Agar consistently demonstrates enhanced recovery rates for these critical bacterial communities in drinking water systems.

R2A Agar is compliant with standard procedures for pour plate, spread plate, and membrane filter methods, making it highly versatile for conducting heterotrophic plate counts. Its unique formulation not only improves recovery rates but also ensures that water quality testing is as accurate and reliable as possible.

Key Features:

• Created for effective enumeration of bacteria from potable water
• Low nutrient medium isolates stressed and chlorine-tolerant bacteria
• Enhanced recovery rates compared to traditional media
• Supports pour plate, spread plate, and membrane filter methods
• Improves accuracy in heterotrophic plate counts

Choose R2A Agar for reliable results in your microbiological assessments and ensure the quality of your potable water meets the highest standards.
