Cresol Red Indicator Extra Pure
SHORT DESCRIPTION
Cresol Red Indicator Extra Pure is a high-purity pH indicator dye widely used in laboratory titrations, buffer solutions, and biochemical assays. It exhibits a clear color change from yellow to red over the pH range of approximately 7.2 to 8.8, making it suitable for detecting slight pH shifts in weakly basic environments. Its stable performance and extra pure grade ensure consistent results in analytical chemistry, molecular biology, and spectrophotometric applications. Ideal for use in precise pH monitoring, Cresol Red should be handled with care and stored away from light and moisture to preserve its integrity.
Eriochrome Extra Pure
SHORT DESCRIPTION
Eriochrome Extra Pure—typically referring to Eriochrome Black T—is a complexometric indicator primarily used in EDTA titrations to detect metal ions, especially calcium (Ca²⁺) and magnesium (Mg²⁺) in water hardness analysis. In its extra pure grade, this dye ensures sharp, precise endpoint detection by minimizing impurities that could cause background coloration or interferences in spectrophotometric or volumetric determinations. It functions by forming a wine-red complex with metal ions, which turns blue when the metal is sequestered by EDTA. Suitable for high-precision analytical chemistry, it should be stored away from light and moisture to preserve stability.
Hydrogen Peroxide Extra Pure
Iodised Salt Extra Pure
SHORT DESCRIPTION
Iodised Salt Extra Pure is a refined form of sodium chloride enriched with a precise amount of iodine, typically in the form of potassium iodate or iodide. It is primarily used to prevent iodine deficiency disorders, making it essential in nutritional and public health applications. Beyond its dietary use, iodised salt also serves in laboratory settings for controlled experiments involving iodine content and salt solubility studies. Its high purity ensures minimal contamination, making it suitable for analytical and pharmaceutical applications where quality and consistency are critical. Proper storage in airtight containers is recommended to prevent iodine loss due to air exposure.
