Violet Red Bile Agar with Glucose, ISO 21528, ISO 11133, 500 g, plastic

Violet Red Bile Agar with Glucose is a dehydrated nutrient medium for microbiology, aligned with ISO 21528 and ISO 11133 for standardized laboratory work. It is intended for hygiene monitoring and microbiological analyses, including nutrient-media applications in the examination of water and related sample types. The glucose-containing formulation supports selective culture workflows used when laboratories need consistent preparation of plates or tubes from a dry base. This suits routine media kitchens and quality-control benches that process multiple batches. Physical handling is straightforward: weigh, dissolve and sterilize according to the chosen ISO method before pouring or dispensing. The medium is offered from manufacturer Carl ROTH for professional use in food, water and environmental microbiology programmes. Clear pack presentation helps inventory control, while the defined ISO references simplify method documentation and audit trails. Suitable for laboratories that maintain validated procedures for Enterobacteriaceae-related testing and broader hygiene surveillance, it integrates into existing dehydrated-media inventories without changing established preparation habits.
