Litmus Granular Extra Pure is a premium-grade pH indicator widely used in laboratories for acid-base testing and educational demonstrations. Derived from natural sources like lichens, this granular form offers a stable, easy-to-handle format suitable for preparing litmus solutions or impregnating test papers. In acidic environments, it turns red, while in alkaline conditions, it turns blue, providing a clear visual response. Its high purity ensures reliable and repeatable results across various applications in chemistry, biology, and environmental testing. Store in a tightly sealed container away from moisture and direct sunlight to preserve its effectiveness.
