Product Description
R2A Agar is a specialized microbiological medium designed for the cultivation of heterotrophic bacteria, particularly from water and environmental sources. Unlike standard nutrient agar, R2A Agar contains lower concentrations of nutrients, making it ideal for isolating slow-growing or stressed bacteria that may be outcompeted in richer media.
This Himedia R2A Agar (SMEB962AL-5X50 ML) is widely used in research labs, educational institutions, and environmental testing facilities. Whether you’re studying microbial diversity in water samples or conducting quality control tests, this agar provides reliable results with consistent performance.
Each pack contains 5 bottles of 50 ml R2A Agar, ensuring you have an adequate supply for multiple experiments. The ready-to-use format saves time in lab preparation, allowing you to focus on your research or testing.

When working with R2A Agar, follow standard microbiological practices. Always use sterile techniques when handling the medium to prevent contamination. Store the bottles in a cool, dry place away from direct sunlight.
The shelf life of this product is typically 24 months from the date of manufacture when stored properly. Check the expiration date on the packaging before use.
For best results, follow the manufacturer’s instructions for preparation and use. The medium should be melted completely before pouring into sterile Petri dishes. Allow the agar to solidify before inoculation.
R2A Agar is particularly useful in environmental microbiology studies. It helps in the isolation of bacteria from various water sources including drinking water, wastewater, and natural water bodies.
Researchers studying biofilm formation will also find this medium valuable. The low nutrient content allows for the growth of bacteria that form biofilms in natural environments.

FAQs
What is R2A Agar used for?
R2A Agar is primarily used for isolating and enumerating heterotrophic bacteria from water and environmental samples. Its low nutrient content makes it ideal for recovering stressed or slow-growing bacteria.
How should I store R2A Agar?
Store R2A Agar bottles in a cool, dry place away from direct sunlight. The recommended storage temperature is 15-25°C. Always check the expiration date before use.
Can I use R2A Agar for drinking water testing?
Yes, R2A Agar is commonly used in drinking water microbiology. It helps detect bacteria that might not grow well on standard media, providing a more comprehensive analysis of water quality.
What’s the difference between R2A Agar and Nutrient Agar?
R2A Agar contains lower concentrations of nutrients compared to Nutrient Agar. This makes it better suited for environmental samples where bacteria may be stressed or slow-growing.
How long does it take for bacteria to grow on R2A Agar?
Incubation times can vary, but typically 48-72 hours at 25-30°C is recommended. Some slow-growing bacteria may require up to 7 days for visible colonies to appear.
