Product Overview
Acetic acid potassium salt (99%+) is a high-purity biochemical reagent designed for precision laboratory applications. This crystalline powder offers exceptional solubility in water and organic solvents, making it ideal for buffer preparation, protein precipitation, and molecular biology protocols. The 99%+ purity ensures minimal interference from contaminants, providing reliable and reproducible results in sensitive assays. Its stable chemical structure maintains pH consistency across experiments, while the low moisture content prevents clumping during storage. The biochemistry-grade specification guarantees compliance with stringent lab standards, ensuring compatibility with enzymatic reactions and cell culture systems. The product undergoes rigorous quality control to verify its identity, purity, and performance, with each batch accompanied by a certificate of analysis. Its neutral pH in solution makes it particularly valuable for maintaining physiological conditions in biological experiments. The fine particle size ensures rapid dissolution without residue, while the tightly sealed packaging preserves integrity during transport and storage.
FAQs
1. What is the solubility of this potassium acetate in water?
This 99% pure potassium acetate has a solubility of approximately 250 g/100 mL in water at 20°C, forming a clear, colorless solution.
2. Can this product be used for DNA precipitation?
Yes, the high purity and low ionic contamination make it suitable for DNA precipitation protocols when used at appropriate concentrations.
3. What is the typical shelf life when stored properly?
When stored in a cool, dry place with the container tightly sealed, this potassium acetate maintains its specified purity for at least 3 years from the date of manufacture.
4. Does this product contain any heavy metal contaminants?
The biochemistry grade specification ensures heavy metal content is below 5 ppm, with most batches testing below 1 ppm for critical metals like lead and mercury.
5. What is the pH of a 1M solution prepared from this salt?
A freshly prepared 1M aqueous solution typically has a pH between 7.5-8.5, making it slightly basic due to the acetate ion’s weak basicity.
