Product Overview
Acetic acid, potassium salt (potassium acetate) at 99%+ purity is a high-grade chemical specifically formulated for molecular biology applications. This crystalline powder is manufactured under stringent quality controls to ensure minimal endotoxin and nuclease contamination, making it suitable for sensitive biochemical processes. Its high solubility in water (up to 250g/100mL at 20°C) allows for precise buffer preparation, while its stable pH buffering capacity (pKa ~4.76) ensures consistent performance in enzymatic reactions. The molecular biology grade designation guarantees compatibility with downstream applications requiring ultra-pure reagents, including DNA/RNA extraction protocols and protein crystallization studies. Each batch undergoes rigorous testing for heavy metals, residual solvents, and microbial contamination to meet international laboratory standards. The product’s hygroscopic nature necessitates proper storage in airtight containers to maintain its chemical integrity over extended periods.
