Violet Red Bile Agar with Dextrose and, Lactose, for microbiology, 500 g

Violet Red Bile Agar with Dextrose and Lactose is a dehydrated nutrient medium for microbiology, formulated as a powder base for the preparation of solid culture media in the laboratory. It forms part of the dehydrated nutrient media range for microbiology and is associated with media according to Ph. Eur., supporting consistent media preparation in life-science and microbiological quality-control settings. The product is supplied in a 500 g pack from manufacturer Carl ROTH, with a unit quantity of 500 g and a pack weight of 0,580 kg. Laboratories reconstitute the base according to standard protocols before pouring plates for microbiological examination. Category placement under life science and microbiology underscores its use as a classic violet red bile-type agar containing dextrose and lactose for routine culture work. The dehydrated format suits media kitchens that prepare batches on demand rather than relying solely on pre-poured plates. Professional users in research, industrial, and control laboratories can integrate this medium into established autoclaving and plating procedures. Clear unit sizing supports inventory planning for recurring microbiological testing programmes that require Ph. Eur.-oriented nutrient media.
