METHYL RED

Methyl Red is a high-quality azo-based pH indicator dye available as reddish crystals, widely used in microbiological and biochemical laboratories. It serves as a dependable reagent for the Methyl Red (MR) test, used to differentiate members of the Enterobacteriaceae family based on their glucose metabolic pathways. It effectively detects mixed acid fermentation by producing a vivid colour transition from red to yellow across its working pH range. Bacteria such as Escherichia coli that follow the mixed acid pathway yield a positive red result, while non-acid producers turn the medium yellow. Ideal for clinical diagnostics, food microbiology, and environmental sample testing, this product delivers consistent and reproducible results batch after batch.

A reliable pH indicator dye in reddish crystal form, used for detecting acid-producing bacteria through glucose fermentation in microbiological testing.
