VRBA (Violet Red Bile Agar) is a selective and differential medium commonly used in microbiology for isolating and differentiating coliform bacteria, particularly in water and food testing. It contains bile salts, crystal violet, and neutral red, which inhibit the growth of non-coliform organisms while allowing the growth of coliforms. The VRBA provides a reliable method for detecting fecal contamination and assessing water quality. Ideal for laboratory environments, this high-quality medium is available at Labtex Bangladesh for your microbiological testing needs.
