Product Overview
This 99.5% pure sodium bicarbonate is a high-grade analytical reagent designed for precise laboratory applications. The fine crystalline powder offers excellent solubility in water (96 g/L at 20°C) and maintains stable pH buffering capacity between 8.0-8.6 in aqueous solutions. Its ACS-equivalent purity ensures minimal impurities (≤0.005% heavy metals, ≤0.01% chloride), making it ideal for sensitive analytical procedures. The product demonstrates consistent performance in neutralization reactions and maintains stability under standard lab storage conditions (15-25°C). Each batch undergoes rigorous quality control to verify the 99.5% NaHCO₃ content and absence of significant contaminants. The uniform particle size distribution (90% passing 100 mesh) facilitates rapid dissolution and homogeneous mixing in solutions. This reagent-grade sodium bicarbonate meets international standards for analytical chemistry applications.
FAQs
1. What is the exact purity level of this sodium bicarbonate?
The product maintains a minimum 99.5% purity level, with heavy metal impurities controlled below 0.005% and chloride content under 0.01%.
2. How does this compare with food-grade sodium bicarbonate?
This analytical grade sodium bicarbonate undergoes additional purification steps to remove trace contaminants, making it suitable for laboratory applications where precision is critical.
3. What is the typical shelf life when stored properly?
When kept in a tightly sealed container at 15-25°C with relative humidity below 60%, the product maintains its specified purity for at least 36 months from the date of manufacture.
4. Can this be used for preparing standard buffer solutions?
Yes, the high purity and consistent composition make it suitable for preparing standard buffer solutions in the pH range of 8.0-8.6 when combined with appropriate acids.
5. What is the recommended storage container material?
Store in the original high-density polyethylene container or transfer to glass/HDPE containers with airtight seals to prevent moisture absorption and contamination.
