Product Overview
Calcium hydroxide (99.995% trace metal basis) is a high-purity reagent designed for demanding laboratory applications where minimal metallic contamination is critical. This fine white powder offers exceptional solubility in water, forming a strongly alkaline solution ideal for pH regulation, precipitation reactions, and as a neutralizing agent in chemical synthesis. The ultra-low trace metal content ensures reliable results in sensitive analytical procedures, including gravimetric analysis and titrations. Its consistent particle size distribution guarantees uniform reactivity, while the absence of significant impurities prevents interference in spectrophotometric or chromatographic techniques. The product is manufactured under stringent quality controls to maintain its high purity, making it suitable for use in research-grade protocols. Its stability under normal storage conditions ensures long shelf life without degradation of its chemical properties. This grade of calcium hydroxide is particularly valued in applications requiring precise stoichiometric calculations, where even minor impurities could compromise experimental outcomes.
FAQs
1. What is the difference between this calcium hydroxide and standard lab-grade?
This product has 99.995% purity with trace metal basis certification, meaning it contains significantly lower levels of metallic impurities compared to standard lab-grade calcium hydroxide, which typically has 95-98% purity.
2. Can this be used for preparing standard solutions?
Yes, the high purity and consistent composition make it suitable for preparing standard solutions where precise concentration is required, though proper drying before use is recommended.
3. What is the typical shelf life of this product?
When stored in a tightly sealed container away from moisture and carbon dioxide, this calcium hydroxide maintains its purity for at least 3 years from the date of manufacture.
4. Does this product contain any binding agents or additives?
No, this is pure calcium hydroxide without any added binding agents, flow agents, or other additives that could introduce contaminants.
5. How should I handle this product to maintain its purity?
Use clean, dry tools and store in a desiccator when not in use. Avoid exposure to atmospheric CO2 which can form calcium carbonate on the surface over time.
