Product Description:
Used as a pH indicator in various laboratory settings to determine the acidity or alkalinity of solutions. It changes color from yellow in acidic conditions (pH below 6) to blue in basic conditions (pH above 7.6), making it useful in titrations and biological experiments. Commonly employed in microbiology to monitor pH changes in cell cultures or fermentation processes. Also utilized in environmental testing to assess water quality, particularly in aquatic ecosystems. In educational labs, it helps demonstrate pH concepts and chemical reactions visually. Additionally, it serves as a dye in microscopy for staining and observing cellular structures.
