Product Description:
Used primarily in microbiology and chemistry labs, this indicator helps differentiate bacterial types based on their metabolic properties. It is a key component in culture media like MacConkey agar, where it identifies lactose-fermenting organisms by turning pink or red. In titration experiments, it serves as a pH indicator, transitioning from red in acidic conditions to green in alkaline environments. Its dual-color change makes it valuable for precise pH monitoring in various analytical procedures.
