Product Description
Violet Red Bile Agar (VRBA) is a widely used selective medium in microbiology laboratories for the detection and enumeration of coliform bacteria. This high-quality agar, manufactured by SRL Chem, adheres to BIS standards, ensuring reliable and consistent results in research and diagnostic applications.
The medium contains bile salts and crystal violet, which inhibit the growth of Gram-positive bacteria while allowing coliforms to thrive. The addition of neutral red as a pH indicator helps in the easy identification of coliform colonies, which appear as red or pink colonies surrounded by a zone of precipitated bile.
Whether you’re a student, researcher, or educator, this agar is essential for water testing, food safety analysis, and environmental monitoring. Its ease of preparation and high selectivity make it a staple in microbiology labs across India.

Key Applications
Violet Red Bile Agar is primarily used for:
- Detection of coliform bacteria in water samples
- Food and dairy product testing for microbial contamination
- Environmental monitoring and research
- Educational purposes in microbiology labs
Why This Product Stands Out
This VRBA agar is manufactured under strict quality control measures, ensuring batch-to-batch consistency. The BIS certification guarantees compliance with Indian standards, making it a preferred choice for laboratories that require accurate and reproducible results.
Unlike generic alternatives, this product is optimized for sensitivity and specificity, reducing false positives and ensuring reliable coliform detection. Its long shelf life and stable performance make it a cost-effective solution for routine microbiological testing.
How to Use Violet Red Bile Agar
Preparing and using this medium is straightforward:
- Dissolve the required amount of powder in distilled water as per the instructions.
- Sterilize the solution by autoclaving at 121°C for 15 minutes.
- Cool the medium to 45-50°C and pour into sterile Petri dishes.
- Inoculate the sample and incubate at 35-37°C for 18-24 hours.
- Observe for red or pink colonies with bile precipitation, indicating coliform presence.
Safety and Handling
While Violet Red Bile Agar is generally safe for laboratory use, it is recommended to handle it with standard microbiological precautions. Wear gloves and a lab coat when preparing the medium to avoid skin contact. Dispose of used plates and contaminated materials as per laboratory safety protocols.
