Product Overview
Calcium oxide powder from BAKER ANALYZED™ delivers exceptional purity and consistency for demanding laboratory applications. This reagent-grade material features a minimum 96% assay, ensuring reliable performance in chemical reactions, moisture absorption, and pH adjustment processes. The fine powder form provides excellent solubility and reactivity, making it suitable for both qualitative and quantitative analyses. Manufactured under stringent quality controls, this calcium oxide maintains low levels of impurities like magnesium, iron, and heavy metals, which could interfere with sensitive experiments. Its high surface area enhances reaction efficiency, while the stable chemical composition guarantees reproducible results across multiple batches. The product comes in a 500g pack size, offering an optimal balance between quantity and freshness for regular lab use. The BAKER ANALYZED™ certification ensures each batch meets rigorous analytical standards, providing researchers with confidence in their experimental outcomes. Proper storage in airtight containers preserves the material’s hygroscopic properties and prevents carbonation from atmospheric CO₂ exposure.
FAQs
1. What is the typical shelf life of this calcium oxide powder when stored properly?
When kept in a tightly sealed container away from moisture, this calcium oxide powder maintains its specified purity for up to 24 months from the date of manufacture. The hygroscopic nature of the material makes proper storage essential for preserving its reactive properties over time.
2. How does this reagent-grade calcium oxide differ from technical-grade alternatives?
This BAKER ANALYZED™ reagent-grade calcium oxide undergoes additional purification steps to achieve higher purity levels (96%+ assay) compared to technical-grade versions. It contains significantly lower concentrations of metallic impurities and other contaminants that could affect experimental accuracy or introduce unwanted side reactions.
3. Can this calcium oxide be used for preparing calcium hydroxide solutions?
The powder readily reacts with water to form calcium hydroxide (slaked lime), making it suitable for preparing saturated lime water solutions. The reaction is highly exothermic, so gradual addition of water with proper cooling is recommended to control the heat generated during the process.
4. What precautions should be taken when handling this powder in laboratory settings?
As a strong alkaline substance, calcium oxide requires careful handling. Always wear appropriate PPE including gloves, goggles, and lab coats. Avoid inhalation of dust by working in a fume hood or well-ventilated area. The material can cause severe skin and eye irritation upon contact, so immediate rinsing with water is necessary if exposure occurs.
5. Is this product compatible with standard glass laboratory equipment?
While compatible with most borosilicate glassware, prolonged contact with calcium oxide may cause slight etching of glass surfaces due to its alkaline nature. For extended storage or reactions, consider using polyethylene or polypropylene containers to prevent potential glass degradation over time.
