Product Overview
Phenol red indicator powder is a synthetic dye widely used in laboratories for accurate pH determination. This high-purity, water-soluble powder transitions from yellow to red across a pH range of 6.8 to 8.4, making it ideal for titration experiments and biological staining. Its stability ensures consistent results in aqueous solutions, while its non-toxic nature makes it safe for routine lab applications. The powder form allows for precise measurement and easy preparation of indicator solutions. Phenol red is particularly valued for its sharp color change, which provides clear visual endpoints in acid-base titrations. Its compatibility with various solvents and minimal interference with reactions make it a preferred choice for analytical chemistry and microbiology applications. The laboratory-grade purity ensures minimal impurities, reducing the risk of experimental errors. This indicator is also stable under standard storage conditions, maintaining its effectiveness over extended periods. Whether used in qualitative analysis or quantitative assays, phenol red delivers reliable performance for critical laboratory procedures.
