Product Overview
Aluminum sulfate 18-hydrate crystals from BAKER ANALYZED™ ACS reagent series represent a high-purity chemical formulation designed for demanding laboratory environments. This aluminum salt appears as colorless to white crystalline solid with high water solubility, making it particularly suitable for applications requiring precise dissolution characteristics. The ACS reagent grade designation ensures compliance with American Chemical Society specifications, guaranteeing minimum assay purity of 98% and strictly controlled impurity levels. The 18-hydrate form provides stable water content, maintaining consistent molecular composition across different storage conditions. These crystals demonstrate excellent stability under normal laboratory conditions while offering reliable performance in precipitation reactions and pH adjustment procedures. The product’s uniform crystal structure facilitates accurate weighing and dissolution, reducing variability in experimental protocols. Manufactured under stringent quality control measures, this aluminum sulfate variant meets the exacting standards required for analytical chemistry applications where reagent purity directly impacts experimental outcomes. The crystalline form allows for easy handling and portioning while minimizing dust generation during use.
FAQs
1. What is the typical shelf life of aluminum sulfate 18-hydrate crystals?
When stored in a tightly sealed container at room temperature away from moisture, the product maintains its specified purity for at least 3 years from the date of manufacture.
2. Are these crystals compatible with standard laboratory glassware?
The product can be safely used with borosilicate glass containers and equipment, though prolonged contact with highly concentrated solutions may require glassware with enhanced chemical resistance.
3. What alternatives exist for applications requiring anhydrous aluminum sulfate?
For protocols specifically requiring the anhydrous form, aluminum sulfate with 0% water content would be necessary, though this variant offers better handling characteristics for most hydrated applications.
4. How should partial quantities be stored after opening?
Transfer unused material to an airtight container with desiccant packs and store in a cool, dry location to prevent hydration changes and maintain crystal integrity.
5. What quality documentation accompanies this ACS reagent grade product?
Each batch includes a certificate of analysis detailing assay results, impurity profiles, and compliance with ACS specifications for complete traceability and quality assurance.
