TCI Cresol Red (0.04% in Water) (C0407) is a ready-to-use aqueous indicator solution formulated for pH determination. Because the concentration is fixed and consistent, it removes the weighing and dissolution steps and improves reproducibility between tests and operators. A few drops added to a sample are enough to observe the characteristic colour transition, making it convenient for routine titrations, teaching laboratories, and quick quality checks. Supplied in a 500 mL bottle, the solution should be stored cool, tightly closed, and protected from direct light.
