Product Description
R2A Broth is a specialized low-nutrient medium designed for the isolation and enumeration of heterotrophic bacteria in water, soil, and environmental samples. Formulated by Himedia, this broth supports the growth of slow-growing bacteria that may be inhibited by richer media. Its balanced composition ensures accurate microbial analysis, making it a staple in research labs, educational institutions, and quality control settings.
Each 10ml vial is ready-to-use, eliminating the need for preparation and ensuring consistency in results. Whether you’re conducting water quality tests, studying microbial diversity, or teaching microbiology, R2A Broth provides reliable performance. For researchers and students alike, this medium is an essential tool for precise bacterial enumeration.

Why R2A Broth is Essential for Microbiology
R2A Broth is preferred in microbiology due to its ability to recover stressed or slow-growing bacteria that standard media might miss. Its low nutrient content mimics natural environments, allowing for better isolation of environmental bacteria. This makes it ideal for applications like:
- Water quality testing (drinking water, wastewater, etc.)
- Environmental microbiology studies
- Biofilm research
- Educational lab experiments
Unlike nutrient-rich media, R2A Broth minimizes overgrowth of fast-growing species, providing a more accurate representation of microbial populations. This is particularly useful in regulatory compliance testing and research where precision matters.
How to Use R2A Broth
Using R2A Broth is straightforward. Simply inoculate the 10ml vial with your sample and incubate at the recommended temperature (typically 20–30°C for 5–7 days). The broth supports the growth of a wide range of bacteria, including those from oligotrophic environments. For best results:
- Use aseptic techniques to avoid contamination.
- Incubate under appropriate conditions based on your target microorganisms.
- Observe colonies for enumeration or further analysis.

Storage and Handling
Store R2A Broth vials at 2–8°C in a cool, dry place away from direct sunlight. Avoid freezing, as this may alter the medium’s properties. Once opened, use the vial promptly to prevent contamination. Always follow standard lab safety protocols when handling microbiological media.
FAQs
What is R2A Broth used for?
R2A Broth is used for isolating and enumerating heterotrophic bacteria in water, soil, and environmental samples. It’s particularly useful for recovering slow-growing or stressed bacteria.
How does R2A Broth differ from standard nutrient broth?
R2A Broth has a lower nutrient content, which allows for better recovery of environmental bacteria that may be inhibited by richer media like nutrient broth.
Can R2A Broth be used for drinking water testing?
Yes, R2A Broth is commonly used in drinking water testing to assess microbial contamination and compliance with regulatory standards.
What is the shelf life of R2A Broth?
The shelf life is typically 24 months from the date of manufacture when stored properly at 2–8°C.
