Litmus Granular Extra Pure

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.

Methyl Red Extra Pure

Methyl Red Extra Pure is a high-grade pH indicator commonly used in analytical chemistry, especially in titration processes to identify the endpoint between acidic and basic solutions. It exhibits a clear color change from red in acidic environments (pH below 4.4) to yellow in alkaline conditions (pH above 6.2), making it ideal for monitoring pH transitions in laboratory procedures. Beyond titrations, it is also used in microbiological media to distinguish between types of bacterial metabolism. This extra pure quality ensures excellent sensitivity, precision, and reliability in both educational and professional scientific settings.

Methyl Red Solution Extra Pure

Methyl Red Solution Extra Pure is a ready-to-use, high-purity pH indicator solution widely used in laboratories for acid-base titrations and biochemical assays. It changes color from red at pH below 4.4 to yellow above pH 6.2, making it highly effective in detecting pH shifts with clear visual transitions. This solution is particularly valuable in analytical chemistry, microbiology (such as the methyl red test in bacterial identification), and educational experiments. Its extra pure grade ensures consistent performance, high accuracy, and minimal impurities, making it suitable for precise scientific applications.

Phenolphthalein Powder Extra Pure

SHORT DESCRIPTION Phenolphthalein Powder Extra Pure is a high-purity pH indicator extensively used in analytical chemistry and laboratory applications. This fine, white to pale pink crystalline powder is colorless in acidic solutions but turns a vivid pink to deep magenta in basic environments, typically transitioning around a pH of 8.2 to 10.0. Its sharp and distinct color change makes it ideal for acid-base titrations, particularly in educational, industrial, and research settings. In addition to its primary role in titrations, Phenolphthalein is also used in various chemical formulations, soil pH testing, and sometimes as a dye component in forensic applications. Although previously used as a laxative, it is now restricted to laboratory use due to health concerns. It should be handled with care—using gloves, protective eyewear, and in well-ventilated areas—to avoid inhalation or prolonged contact. Store in a cool, dry place, away from strong oxidizers and light.

Phenolphthalein Solution Extra Pure

SHORT DESCRIPTION Phenolphthalein Solution Extra Pure is a laboratory-grade pH indicator solution, commonly used in titration procedures to determine the endpoint of acid-base reactions. It is prepared by dissolving phenolphthalein powder in an appropriate solvent, typically ethanol or water-alcohol mixtures, resulting in a clear, colorless solution that turns vivid pink in basic conditions—usually in the pH range of 8.2 to 10.0. This high-purity solution offers excellent sensitivity and reliability for analytical chemistry, quality control, and educational demonstrations. It is especially favored in alkalinity testing, neutralization reactions, and various standard laboratory protocols. Proper handling is essential, including the use of gloves and eye protection, as the solution may cause skin or eye irritation upon contact. Store tightly sealed, away from direct light and incompatible substances like strong acids or oxidizers, to maintain its stability and effectiveness.
