Phenol Red ACS

Phenol Red ACS (Analytical Chemistry Society) is a chemical reagent commonly used in laboratory applications. It is a pH indicator that changes color in response to variations in the acidity or alkalinity (pH) of a solution. Phenol Red is often employed in experiments involving cell cultures, microbiology, and various chemical assays to monitor pH levels. Its color transitions from yellow (acidic) to red (neutral) to bright pink (alkaline) over the typical pH range. This characteristic makes it a valuable tool for researchers and scientists to visually assess and measure pH changes in their samples with precision and accuracy.
