About PHENOLPHTHALEIN INDICATOR PAPER

PHENOLPHTHALEIN INDICATOR PAPER consists of high purity Phenolphthalein indicator embedded in cellulose-based paper strips. These flat rectangular strips are laboratory grade and exhibit high sensitivity in pH testing applications. When in contact with alkaline solutions, the indicator undergoes a color change from colorless to pink, indicating the pH level falls within the range of 8.2 to 10.0. With a shelf life of 2 years under recommended storage conditions, these odorless strips are ideal for acidity/alkalinity testing in laboratories, educational settings, and industrial pH analysis.
