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. Checks pH in labs. Indicates pH in cell culture. Identifies bacteria in microbiology. Tests blood and urine pH. Teaches about pH in schools. Monitors water in fish farms. Measures pH in natural waters. Tests pool and spa water.
