Aluminium Sulphate Anhydrous Extra Pure
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.
Calcium Chloride Extra Pure
Calcium Chloride Extra Pure is a highly pure, hygroscopic compound widely used in laboratory applications as a desiccant, electrolyte source, and reagent in analytical chemistry. It is effective in moisture control, gas drying, and as a coagulant in biological and biochemical processes. Its strong affinity for water also makes it valuable in experiments involving freezing point depression, exothermic dissolution, and ionic reactions. The extra pure grade ensures minimal impurities, which is critical for accuracy in quantitative analysis, buffer preparation, and synthesis. It should be stored in well-sealed containers in a dry environment to prevent clumping and preserve its chemical performance.
