Aluminium Sulphate Anhydrous Extra Pure

Original price was: $ 18.00.Current price is: $ 17.84.
Aluminium Sulphate Anhydrous Extra Pure is a high-purity, white crystalline or powdery solid commonly used in laboratory chemistry as a source of aluminum ions for precipitation, titration, and coordination studies. Its anhydrous form provides a concentrated and stable option for applications requiring precise control over water content, such as analytical reagent preparation, pH adjustment, and synthesis of other aluminum salts. This compound is also used in paper sizing experiments, dye fixation, and water treatment research. The extra pure grade ensures very low levels of contaminants, supporting accurate and reproducible results in sensitive experimental work. It should be stored in airtight containers in a dry area to prevent moisture absorption and preserve its chemical integrity.
