Product Overview
Calcium Sulfate Dihydrate AR is a high-purity, chemically stable compound widely used in laboratory settings for its consistent performance. With a purity level of 99% or higher, this analytical reagent (AR) grade ensures minimal impurities, making it suitable for precise chemical analysis and experimentation. The dihydrate form retains two water molecules per calcium sulfate unit, contributing to its stability under standard conditions. Its low solubility in water (0.24 g/L at 20°C) and inert nature make it an excellent drying agent and desiccant in controlled environments. The powder or crystalline form allows for easy handling and accurate measurement, ensuring reproducibility in experiments. This compound is particularly valued for its role in gravimetric analysis, where precision is critical. Store in a cool, dry place to maintain its integrity, as exposure to moisture can alter its properties. Whether used in qualitative or quantitative analysis, Calcium Sulfate Dihydrate AR delivers reliable results, making it a staple in research and educational laboratories.
