• Description: Phenol red is a pH indicator that finds broad applications from chemistry to microbiology. Colour varies from yellow at pH<6.8 (lmax 443nm) through to light red/pink at 6.8<pH<8.2 (lmax 570 nm) to vivid purple/red at pH>8.2. It is widely used in cell culture to monitor pH and for colorimetric titration. For example, phenol red can be used to quantify Br- content in sea or fresh water. It is added to VTM as pH indicator, at the concentration of 10mg/ml, maintaining a pink colour at neutral pH.
