Product Name – Boric Acid 99.5% Molecular Biology Quantity/Pack Size – 500 g Form – Crystalline Powder Grade – Molecular Biology Application – DNA/RNA electrophoresis, buffer preparation
Product Overview
Boric Acid 99.5% Molecular Biology is a high-purity crystalline powder designed for precision in molecular biology applications. Its exceptional 99.5% purity ensures minimal interference in sensitive procedures like DNA/RNA electrophoresis, where even trace impurities can compromise results. The compound’s consistent pH buffering capacity makes it ideal for preparing Tris-Borate-EDTA (TBE) and other electrophoresis buffers, providing stable ionic conditions for nucleic acid separation. Unlike lower-grade alternatives, this molecular biology-grade boric acid undergoes rigorous quality control to eliminate contaminants like heavy metals and endonucleases, safeguarding experimental integrity. Its fine, free-flowing powder form dissolves rapidly in aqueous solutions, reducing preparation time while maintaining homogeneity. The product is packaged in a moisture-resistant container to preserve purity during storage, ensuring long-term reliability for repetitive lab use. Whether for routine gel electrophoresis or high-throughput sequencing workflows, this boric acid delivers reproducible performance, eliminating batch-to-batch variability that can plague lower-grade reagents.
FAQs
1. What is the solubility of this boric acid in water at room temperature?
This boric acid dissolves at approximately 5.7 g per 100 mL of water at 25°C, forming a clear, colorless solution when fully dissolved.
2. Can this boric acid be used for making TBE buffer without further purification?
Yes, the 99.5% purity level is sufficient for direct use in TBE buffer preparation without additional purification steps, as it meets molecular biology standards.
3. How does this compare to boric acid labeled as “ACS grade”?
Molecular biology grade boric acid undergoes stricter testing for nucleases and heavy metals compared to ACS grade, which is primarily assessed for general chemical purity.
4. What is the recommended storage condition to maintain its purity?
Store in a tightly sealed container at room temperature, away from moisture and direct sunlight, to prevent caking or degradation.
5. Is this product compatible with agarose gel electrophoresis systems?
Yes, it is fully compatible with agarose gels and commonly used in conjunction with Tris and EDTA for nucleic acid separation.
